Cross brand pattern interpretations: Dubied to Brother

Reviewing Brother carriages: I am drawn to published pattern books for different brand machines at different periods of time and enjoy the puzzle of converting their designs to machines I have ready access to.
At this point in time most of my swatches are produced on a 930 using img2track to download files when needed while still making an attempt to share repeats usable on punchcard knitting machines when possible.
I have never been in the same space as a Dubied, but have been researching online trying to gather any information that might help me translate more of the patterns presented in the manual “for developing your hand and machine sampling”. These are my personal notes, not meant as accurate teaching tools, but shared to perhaps serve some use to others when decoding cross-brand pattern instructions.
Close to the completion of this post, I acquired the manual for the Dubied N4 model from a friend, with these images and some variations of the text. The associated tools from an online sale site: Manuals available online for free download 

Another source of inspiration for a different machine, Italian text only available, with many similar stitch structures: The Coppo numbering for settings in a box format My initial attempts to develop an understanding of functions began with an illustration from the Dubied N4 parts manual Some related functions, the term cardigan is used to refer to what many of us know as tuck stitch.   Visualizations of mirrored matching cam lever positions on opposite beds.  These machines do not create patterns via punchcards, instead, cams inside the carriages are controlled by switches that alter stitch formations. They are classified by the inclusion of the following symbols
N: equipped with rib and tube cams
F: equipped with cardigan cams for the execution of all tuck stitch fabrics
H: fitted with high and low butt needles. The raising cams operate either all the needles or high butt needles only. All machines with these needles are equipped with cam-plates allowing all the knit-and-tuck or all-tuck combination fabrics to be formed
4: 4 yarn carriers, which can be placed on either side and allow the manufacture of different pieces at once.
Basic rib structures are modified further by positioning needles in specific needle arrangements.
Functions and settings are often represented in manuals and publications in varied ways. The N4 manual supplement shows an undercarriage numbering system that uses a different sequence than my illustrations. The particular model introduced the addition of auto cams, allowing for alternate function patterning on needles in different positions.  I find it easier to think of settings on each bed separately, especially in cases where bed instructions also need to be reversed.
This is my initial effort at illustrating comparisons between the Dubied and Brother settings for knitting specific swatches.
Any fabrics acting on stitches occurring on selective tuck or slip stitches on one or both beds would need to be programmed in Brother machines for patterning on the top bed. On the ribber, the use of lili buttons will automate card 1 needle selection in the pattern on an even number of needles, but in many instances, in executing the Dubied patterns, hand selection in specific needle arrangements may be required as often as every row.  Information from N4 pub after I had created the above, with additions and some paraphrasing: the numbering system for “keys and levers”  Key positions:
1. closed if turned toward the inside of the carriage, no rows will be knitted ie slip stitch in both directions for a free pass, no knitting, with no yarn using Brother
2. opened if turned toward the outside/ away from the carriage, rows will knit
3. central position for floating threads on the low-heel needles, knit/slip, programming for needle selection in upper work, Brother D, and lower, Brother B, or limited Brother ribber selections using lili buttons
Stitch size dials:
Numbering from 1-20, two on the front carriage, two on the rear carriage, three  lengths can be set using the stitch size dial, indicated by three colors red, black, and green  (Cardigan) Levers: each lever can be positioned separately:   pointing toward the outside of the carriages/ back: the space between them  neutral/middle: if activated will hold the thread on all needles (tuck loops across all needles in work)pointing toward the inside of the carriage/ forward: if activated will hold the thread (form tuck loops) on the low heel (non-selected needles in Brother)Sliding unladen (no yarn) carriage/ free pass: made with keys 1, 2, 3, 4 closed/ Brother carriages set to slip in the direction of knitting
Plain knit or any rib setting: Keys  1, 2, 3, and 4 open the carriages work on selected needles, levers facing outward/ Brother with both beds set for plain knitting

Combining knit carriage needle selection with racking 2017 and
A racking tale: Passap/Brother 3  in 2019 used this repeat as the springboard for textures that did not match the original in stitch and row counts or racking sequences. The racking handle position is referred to as up or down, similar to the Passap system.  The ribber is used as the front bed.
I initially interpreted a round as a single row of knitting and held onto that for a while, and my arrangement for needles in and out of work on either bed was reduced.
Sometimes there are good reasons why our swatches do not match the inspiration one, a bit like changing ingredients in a recipe and wondering why the result is different.
The first test: in practice, I was simply unable to get the ribber to rack by 4 positions after only 3 knit rows, the problem was solved by a change in the needle arrangement and racking by only 3 positions in either direction. Another option would have been to add more all-knit rows between racking sequences as seen in the subsequent Coppo machine pattern adaptation, creating deeper folds.
The tension was adjusted to the tightest possible and remained fixed with no variations on either bed.
The gauge is likely looser than that in the Dubied manual, forming larger stitches and resulting in a softer shape definition.
Brother tension adjustments can only be made on one dial on either carriage, while the Dubied offers multiple settings on both beds.
To knit manually changing ribber settings, cast on with racking position on 7.
After casting on and transferring stitches up to the top bed the needles are arranged as follows, blank cells represent needles placed out of work back to A position: 1. Knit 3 rows on both beds
2. Set the ribber to slip in both directions, knit 3 rows on top bed only, and rack to position 10
3. Set the ribber to knit, knit 3 rows on both beds
4. Set the ribber to slip in both directions, knit 3 rows on top bed only, and rack back to position 7.
Repeat the 4 steps, ending with 3 knit rows before binding off.
Elongated stitches happen on the bed with needles out of work, in this case, the ribber, and the texture will appear on the knit side.
The needed racking positions become easy to identify as the knitting begins to grow. If one wishes to track hand techniques along with their respective row numbers and racking positions a spreadsheet can quickly be created including specifics ie in this case row counts, ribber settings changes, and racking positions:  Automating the selection, and swapping beds make the process easier to track: begin on racking position 7, inverting the needle arrangement in order to keep the same racking sequence.  Cancel end needle selection whenever any needles are out of work on the main bed and the knit carriage is set to slip in both directions. It is not always necessary, but a good habit to develop.  The width of the main bed is programmed using a repeat that has 3 rows of punched holes/black pixels, followed by 3 unpunched rows/white pixels repeated X2, for a total of 12 rows. Emptied needles on the knit bed are pushed back out of work to the A position. All ribber needles are in the work position.
Needle preselection in Brother on the knit bed will not interfere with racking since ribber needles are continuously in the B position.
Cancel end needle selection, KCII, as in any fabric with slip stitch selection on the top bed combined with needles out of work.
After the repeat is programmed and the first preselection row has been made, racking will happen every 6 rows, first to position 10, and then back to 7.
Starting side does not matter unless color changes are intended on every even number of rows.
Elongated stitches happen on the bed with needles out of work, the texture will appear on the reverse side, where all needles are in work (NOOW). The blue is knit with NOOW and with setting changes on the ribber every 3 rows, while the yellow swatch is knit with the main bed programmed with NOOW and a 12-row repeat using the slip stitch setting in both directions. When a round is interpreted as 2 rows of knitting, the carriages leave and return to the same side, color changes can be considered. The out-of-work/in-work needle arrangements now match the published counts, along with the repeat for knitting with the top bed set to slip and knit rather than the ribber. The method is the same as previously described.
Racking is now planned by four positions, and occurs every 12 rows once the needles are all preselected on the top bed, starting at racking position 6, to 10, and back to 6, producing a swatch matching the original.  What about adding color changes? An easy place to change color is when the needle selection changes from slip to knit, with each color knitting for 6 rows, remembering to also rack after every 12 rows.
The brown yarn was hard to see clearly on the needle bed. When off the machine there were interesting unplanned areas of dropped stitch lace where dropped stitches on the top bed had been missed.
Tabling the idea of adding other colors to this particular pattern, at least for now, but never say never in knitting (and baking).  And then there is this related pattern in the manual that involves racking by 4 positions and deliberately dropping stitches With some experience needle setups can be varied to suit, while achieving the same results as published illustrations.
I prefer to start with racking to left, as a result, the shapes in my swatches are mirrored horizontally when compared to those in the manual’s photo.
There are ways to make casting-on quick for testing small swatches when permanent edging starts do not matter.
One method to do so was described in the post: Ribber cast on comb/ open stitch single bed cast-on and was used here.
Ribber cast on combs traditionally came in different colors. I happened to try to use one of my grey ones presumably a Studio 4.5 mm one and found the spaces between its teeth not matching that between my Brother machine needles evenly. There were no issues when using the “silver” Brother comb. Here it is shown in position, with stitches cast only on the top bed,  and picking up loops for stitches on the ribber as the carriages travel to the opposite side. The plan is to move ribber stitches to the left by two positions three times before returning them to their original position.
The ribber carriage is set manually to knit on dark yarn rows and to slip on light yarn rows.
The ribber setting “song”: light/ slip levers up, dark / slip levers down.
The dark forms the dropped stitch lace pattern, it is thinner than the light yarn and the knit steams fairly flat.
Stitches are dropped by disconnecting the ribber carriage and making passes with no yarn, first to drop the stitches, and then to couple it once more with the knit carriage to continue knitting.  Automating the pattern, switching beds: program a 12-row repeat for 2 rows slipped, 2 knitted across all needles in work.
Note to self, when you swap beds and the ribber is forming all the knit stitches, do not use the ribber carriage to drop all the stitches on it!
Both yarns here are thin, and steam/press fairly flat.
If a ribber cast on for every other needle is used, remember to change the pitch from P to H after the transfers between the beds have taken place. A check to confirm that indeed needles will not smash into each other is quick to perform and well worth doing before continuing.
My needle arrangement:

It is interesting that the swatch photographs accompanying directions in the Coppo manual are not “perfect”, some showing pattern adjustments or even sporting holes not part of the design. This texture is very similar to the above

I initially interpreted 4 rounds as meaning 4 rows of knitting.
The resulting adaptation: cast on with the racking indicator on 6. The red numbers illustrate the guide provided in the publication and the bold black count adjustments in the actual knitting of the pattern. if attempting to match the original the 6 rows knit on the top bed should actually be 8 prior to racking.
The racking handle is set to 6
1. Knit 4 rows on both beds
2. Knit 4 6 rows on the top bed only
Rack by 4 positions, no direction given, I chose left to 10
3. Knit 4 rows on both beds
4. Knit 4 6 rows on the top bed only
Rack by 4 positions, I chose right to 6
Repeat steps 1-4
The elongated, slipped stitches are formed on the ribber, the bed with needles out of work, and the texture will appear on the knit side.
In any racking, the ribber bed may move beyond the stitches on the knit bed as the carriages move past the needles originally cast on and past the end stitch on one side or the other. This can help create some interesting side edgings.
That said, the first test swatch is knit changing ribber settings from knit to slip. If all needles are in work and the slip stitch setting is used, a float will be formed on the ribber if it has moved beyond the last needles in work on the opposite bed until the yarn reaches the stitches on the main bed as well.
It will not be an issue if stitches on that side are transferred up to the main bed. Automating the process, the beds are reversed, the repeat is now 20 rows high, and the knit carriage will be set to slip in both directions. The needle setup matches that given by the manufacturer.  Empty needles are pushed back to the A position after transfers.
Racking happens every 10 rows, just after every needle in work preselection on the main bed. This pattern utilizes the cardigan/tuck function and requires thicker yarn. The wool used here is a 2/8 weight, knit at as tight tension on the ribber as possible, in this case, 6. Here the instructions for knitting include references to specific numbers of rows rather than rounds. I was unable to reproduce anything like this sample in the manual with the illustrated needle arrangement, revised it.
The revised needle arrangement allowed for forming a vertical single-stitch column as in the swatch, and the racked patterns occurred at the center of a purl ground.
The swatches are knit in different wool weights. Racking happened by 2 positions after each round/ pair of knit rows, starting side did not matter.  The above were knit using the slip stitch setting.
Reviewing the manual once more, it was noted that the sample was in the center of a page with the heading: racked fabrics in the cardigan/ tuck stitch. The stitch formations using tuck stitch on alternating Brother and Passap beds are reviewed in the post on Fisherman and English rib.
No specific lever or key instructions were provided. The general advice given to knit the cardigan aka fisherman’s rib is to start with the Dubied carriage on the right, all keys open, and push lever 8 (front left) and lever 6 (rear right) to a neutral position (9). In the outward direction, the carriage knits along the rear needle bed and holds the thread on all the needles of the front needle bed; on the return, it alternates the processes, a tubular tuck.
On Brother, it would be done by selecting opposite tuck buttons, making either the selections on the left or on the right That is simply not happening with the pattern needle arrangement on a Brother machine, there are not enough stitches on opposing beds to anchor down tuck loops.
Half fisherman, aka English rib, tucks on every needle in work on one pass and knits every needle on the same bed on the return pass.
The new swatch is knitted using the same modified needle arrangement as added to the photo from the manual, starting from the right, with the ribber carriage set to tuck to left, knit to right, and the main bed set to knit every needle.  The swatch is shown in progress on the machine with needle placement as it would appear in the starting setup prior to knitting 2 rows.
The first row tucks on ribber needles when traveling to the left, the second knits on them when returning to the right, followed by racking 2 positions to the left.
Two more tuck/knit rows are followed by racking by two positions back to the right, in the starting needle arrangement.
The manual image is shown on the left, and the Brother swatch, mirrored horizontally, is shown on the right.  The following Dubied knit was particularly interesting to me and reminded me of this sample knit single bed in a previous post. Autocams are drum pattern devices that attach in pairs to the Dubied carriage that modify the stitches much like a punchcard would. It is a drum with pegs of different sizes and positions which rotates with a pass to the opposite side. The cams are selected by fingers.  The description is evocative of the Passap needle pattern selection in response to its pusher placements.
To execute this swatch, the top bed was programmed with a repeat suitable for punch card machines.
Guilloche fabrics are made with rows of stitches where tuck and knit stitches are combined and alternated for multiple fixed needle selection rows.
The working theory on converting the published instructions:  While the program eliminates having to change cam buttons manually on the top bed, the ribber settings need to be changed with each color change.
The tucks happen on both beds for 6 rows, so it is a necessity that any Brother sampling is knit using thin yarns. Here the dark is a 2/20 wool, and the light is a 2/28 unknown fiber, possibly acrylic, knit at tension 4 on both beds.
End needle selection is on, KCI.
The repeat is 12 rows in height.
Color changes and carriage settings happen every 6 rows.
The first preselection row is toward the color changer, the design will begin with a tuck pattern on the top bed and the ribber set to knit. On completion of the first 6 rows, COL, every needle on the top bed will have been preselected to the D position, the warning that a color carriage setting changes are due before continuing to knit. The top bed remains set to tuck but will subsequently knit every needle. The ribber needs to be manually set to tuck in both directions.  Upon completion of the 12-row repeat, with COL once more, the top bed will have been preselected in the tuck pattern, the warning that color and carriage setting changes are due before continuing to knit.
The ribber is set to knit once more, and the process is repeated.
Two views of the needle setup:  A small proof of concept One from the Italian language supplement:  For this fabric, the ribber needles need to be manually selected for every other pair of rows. Needle selections on the top bed provide clues as to what the settings should be on the ribber as in the previous swatch.
The top bed is programmed with a repeat suitable for punchcard machines The needle arrangement was set up as given. The end needle selection is on,  set to KCI.
The main bed remains set to tuck in both directions.
The colors and settings on the ribber are both changed after each 2-row sequence.
The ribber needles need to be manually selected with 1 needle up to the E position for knit stitches followed by 2 needles in the B position for tuck stitches repeating across the knitting width.
The ribber settings also need to be changed and set to tuck in both directions so that the needle selection will knit on the “high”, and tuck on the “low” needles as in the Dubied.
When the two ribber tuck rows have been completed, with the next color change, COL, the ribber carriage is set to knit in both directions once more and patterning reverses beds. 

A simple plaid idea using the slip setting: the 32-row repeat shown on the far right was programmed, and color changes happen after altered preselection on the top bed.
The dominant color (white cells) knits on all needles, while the contrast (dark cells) knits on the ribber only while stitches skipped on the top bed become elongated as they are skipped. Things to consider:
A. when first changing colors, the yarn may drop the first few stitches or for other reasons even drop a whole row. If the knitting is started on waste yarn prior to any permanent cast-on for the piece, one can insure that color changes happen properly and asses the proper tensions for the yarn used on the specific needle arrangements.
B. the ground color in this instance is changed after 16 rows, the contrast at far shorter intervals. Lengths will form on the color changer side of each contrasting color. They can be intentionally lengthened further so that at the completion of the piece they may in turn be cut, resulting in yarn ends long enough to be woven into the rib. If doing so, make certain those first few stitches after the color change form properly. There are other ways to handle yarn loops and ends like these, test any favorite on long enough swatches first.
C: all rib areas will be slightly wider than those where only a single bed knits
D: in the areas where only a single bed knits there will be some narrowing. Revisiting Large eyelet lace, hand transferred (or not) 2013
It would appear the original cast-on for this is performed on the double bed with transfer to the front of all rear stitches.
To duplicate in Brother, cast on every other needle, and transfer all stitches to the knit, top bed, or cast on the top bed. The fabric benefits from the use of even weight.
This sample uses 2/8 wool, tension 8. The setup was changed slightly, resulting in empty needles at alternating side edges.
Planning out the repeats on a multiple of 4+2
The edge stitch is moved as well. As recommended in the instructions, all empty needles are left in work position B or pushed to E prior to knitting the next row. Knit one round translates to knit 2 rows, which happens after each row of transfers, the carriage will move from and return to the same side.
The swatch in progress, watch for any loop formation on either side: As with any time in knitting when there are 2 side-by-side empty needles, the loops on those needles will not form stitches, but rather, ladders with each carriage pass. The transferred stitches have been knit for 2 rows, so the transfers are made again of single stitches onto the loops on either side of them, securing the loops before knitting continues. Here there is an empty needle on the far left, and here on the far right The resulting swatch, with a dropped stitch I missed on a row shortly after casting on Before binding off, after a single row is knit, drop one of the double loops, insert a single eye tool back to front, turn it clockwise, and lift the result onto the now empty needle, essentially creating an e-wrap. Work across the row, knit at least 2 rows, and bind off loosely.

Another racking tale: Passap/Brother 5

I taught in a design school in a lab with Brother Punchcard models, four 910s, and 2 bulky machines. My previous experience had been using Passap and Studio electronics, and a crash course in Brother models followed my being hired.
My E 6000 was purchased from a sewing machine center at a time when the owner decided knitting was not for her.
The 560 Studio model was later upgraded with a change in their box in exchange for my publishing some patterns for the Studio Design Magazine but was sold years ago.
There were years the Passap was my production machine for garments and accessories knit double-bed. Single-bed knits for the same end use were easier to knit on Brother, with a clear view of stitch formations vs the issues with seeing the fabric or correcting errors when working with the ribber in place.
The immediacy of easy testing with img2track on the 930 results in nearly all of my recent blog swatches.
There are still days I admit I do love the E6. The console commands along with the lock setting and pusher options on the back bed make a range of fabrics possible that are far harder to achieve in Japanese model KMs.

FB shares have led me down rabbit holes I may not otherwise have entered.
In the machine knitting group, someone recently shared a series of scarves knit using the E6, providing the Duo80 diagram and the E6 technique number.  The setup is for a 2/2 rib, reverses the pusher positions, but produces the same knitDuo 80 symbols AX = Tuck, setting is the same in both the Duo and the Passap back locks
AX  serves the same function in the Duo, and is replaced by KX on the E6 front lock
The arrow keys on the back lock work the same on both machines.
Passap preselects and works on pushers initially placed in work or rest on both beds, whether manually or by console selections in the E6.
Brother preselects needles in the planned pattern on the knit bed subject to punched holes or programmed pixels, but not on the ribber, other when using lili buttons, and that comes with rules and the sole automatic repeat ie the that the number of needles in use on the ribber must be even. On the Passaps there are no such rules on the back bed.
With no arrow keys selected the same action is repeated until the lock setting is changed, so in the above, the change is made by manually setting the back lock to N for 2 rows, then back to AX for tuck on both Passap models.
The front bed in the Duo also has a fixed pattern selection, requiring the lock change to N there as well. The E6 built-in pattern selects the all-knit rows, so its lock remains in the KX setting.
The initial pusher setup is manual on both models but not location-dependent in this particular design.
The E 6 console will select the proper pattern based on the pushers in the work position. A look at pusher positions from the E6 manual. Each machine brand has its own specific vocabulary for parts and techniques. Things get a little more complicated on Brother, it is helpful to have an understanding of stitch formation on both beds before tackling more complex knits.
In Brother the needle placement on the main bed matters as it does in tuck lace, so it needs to be verified before any knitting. “Air knitting” is one easy way to do that. Rows 5 or 6 would provide the necessary preselection.
In any punchcard model or Japanese electronic machine, the knitter is usually in charge of keeping track of racking. The E6 provides console prompts for racking positions in this design, facilitating the process.
An attempt to visualize what actions need to happen on the Brother models: the needle setup will match the Duo or the rotated E6 version Considering the required patterning for each bed, empty columns in my charts represent needles that need to be pushed back to A and left out of work on both beds. Textured ladder spaces will not be formed on either bed as is seen when using similar repeats on the single bed. Adding the ribber position and configuration  The top bed can be programmed, this 24-stitch version is suitable for use in punchcard machines. The main bed will knit all needles programmed with punched holes or black pixels and will tuck unpunched squares or white pixels.
The ribber requires setting changes after the initial four and after the last 2 rows of each 6-row repeat.
In addition, there are racking changes after each repeating segment.
In this setup, there will be a knit stitch beside each tuck one up to the all knit rows, helping to anchor the tuck loops. Ribber carriage settings are noted.  Anytime there are needles out of work, cancel the end needle selection. Depending on the machine model being used the repeat may need to be mirrored horizontally to match my in-process photos, true in my 930.
Using design row 5 or 6, air knit a row to find needles that need to be in work on the knit bed. Push non-selected needles out of work, and back to the A position. After doing so, reset the pattern to design row one.
The setting for the racking indicator does not specifically matter. It is often best to consider this before casting on. Here racking is only by one position, avoid 1 or 10. Starting at 5 centers stitches in relationship to each other stitches. As knitting progresses, where the ribber needle positions become obvious and less reliant on checking numbers. Cast on bringing appropriate needles into work on the ribber.
The original needle setup.  Use any favorite cast-on method.
Starting side does not matter unless one is planning on using a color changer, in which case the first preselection row needs to happen from right to left.
Since needles will be manually pushed up to the hold position, make certain that the ribber carriage is not set to hold. In a test swatch, knit several all-knit rows before beginning the pattern. If planning a piece, start with waste yarn and ravel cord prior to casting on with “garment” yarn.
A tool that aids in selecting every third needle is extremely helpful The initial carriage setups used for rows 1-4 The placement of the first needle on the ribber with respect to that of the first on the main bed The first needle in each pair of rows on the ribber needs to be brought up to the E position in every row for the first 4 rows of the 6-row repeat, I began with the first ribber needle on the left. The needles brought up to E will knit, and help anchor down the knit bed tuck stitch on their left, and the needles on their right will tuck. In turn, the main bed selected needles will anchor loops formed on the ribber, the nonselected will tuck.
The appearance after the tuck loops have all been formed and the needles holding them up to that point are preselected forward just prior to the 2 all knit rows. The knit carriage is left on tuck in both directions, while the ribber is set to knit for 2 rows. It is not necessary to change the P lever to R, with the other buttons set to N, knit is king.  Time to rack so that the first needle on the ribber will now be to the left of the first on the main bed. Push down lightly on the first 2 ribber needles on the left before racking in case those first stitches are a bit snug, to avoid starting needles crashing into each other as you move needle positions.  Knit 2 rows.
Rack again to the initial position,  change ribber settings again, and repeat the process as described. The proof of concept: the error shows what happens when one misses changing the ribber settings back to tuck.  If that is not challenging enough, add a color change, knitting the first 4 rows using color one, and the 2 all-knit rows with color 2.  I used to tell my students to develop a sort of tune that could be sung (mentally) as a reminder of the steps in complex fabrics ie bring up 1, 2, 3, 4, rack, change color, change settings, knit 2, rack, change color, change settings, bring up, etc. but my advice if you really want to knit this fabric in a full piece is to borrow and E6 or pay someone else to knit it for you 😉

Double bed embossed patterns

Some of the previous blog posts containing applicable samples:
Ribber fabrics with stitch transfers between beds 1Slip stitch patterns with hand transferred stitches, double bedBrother shadow lace, rib transfer carriage Combining knit carriage needle selection with racking   Racked patterns 5: Passap/Brother 2
directions and samples from manuals including racking on tuck stitch and other ground variations, this on a tucked ground, in a thin yarn 

Embossed, raised textures are familiar in single bed work using stitch structures such as tuck, slip, weaving, gathered and ruched hand techniques, and in double bed as pile, blister, lace, and ripple patterns.
When embossing is done double bed, the background fabric is knitted in purl stitches on one bed, and the raised design or panel in knit stitches on the other. The first method produces double knit patterns where all needles are working on the back bed, coupled with selected needles for the pattern on the opposite be. The raised, embossed portion is a double knit, showing relief on a purl ground. The second method is to use knit/ purl combinations, easiest to execute with a G carriage.
The striped ground occurs in areas where there are no needles in work and selected for patterning on the main bed. A cabled pattern to try: color changes in these instances are every 2 rows.
Because there are needles completely out of work on the main bed along with pattern selection, this is an instance where end needle selection must be canceled.
The first preselection row is from right to left toward the color changer.
Any transfers or stitch manipulations between or on either bed are made before the first pass to the right with the next color.
The knit carriage is set to slip both ways on the first pass in pattern from the left and stays there, the ribber is set to knit in both directions throughout. Depending on the yarn and the pattern distribution the all striped areas will be longer than those gathered by slipped rows. As usual, begin with a plan. After the first preselection row, transfers are made down to the ribber as indicated at the top of the chart. Cable transfers are made after every 14 knit rows, with stitches crossed on rows 15 and 31. After the cable cables are twisted, the stitches in the color that is going to knit in the next pass are brought out to E so they will knit in that color before the pass to the right, and again before the pass to the left, rows 16 and 32, Y.If the intent is to have solid vertical columns of color, those areas as in column marked A, need to be adjusted for using alternating colors as well. Using the repeat on the left of the chart After the first preselection row to left, transfers are made down to the ribber, stitches that will compose cables are selected in the pattern,
colors are changed after return to the left, and every 2 rows, stitches in the color that does not knit become elongated. Because column A was not color separated for alternating colors, each color in the corresponding needles will knit with every two carriage passes, and the result will be a striped vertical column Cable twists should be planned to retain the correct movent, can alternate each time or repeat in series, charts for location and direction of twists are helpful to avoid errors. The solid vertical columns here are planned in only one color, could be programmed to alternate as well. The repeat used in my swatch includes a solid column on each side of the finished piece, the color swap in the twist at the top can be an unplanned error or serve as a deliberate design change

Analyzing the stitch structures involved for planning 2 color DIY:
two-color ribs on a striped ground require cards or electronic repeats that select each color alternately. Fabric where the backing on the ribber or back bed in machines such as Passap knits all stitches every row is often referred to as half or full Milano. The backing may be also be knit using slip/ tuck settings.
Working in a single color, in half Milano and every needle rib course is followed by a plain knit row on the opposite bed, it is a 2-row repeat. In full Milano fabric, a row of every needle rib is followed by a plain knit row on one side of the fabric, and then by a plain knit course on the other. The repeat is three rows high. On every third row, the ribber carriage must be set to slip for one row, in the direction in which the carriage will be moving, prior to knitting a row with every needle preselection on the top bed. The setting is changed back to knit for 2 rows when the carriages reach the opposite side. The required cam change will happen on alternate sides. Both sides of the fabric have small stitches alternating with longer ones formed by slipped rows. half Milano full MilanoOften an all slip setting is used on the top or front bed, the result has less elasticity than a full needle rib, and the knit will have a tendency to curl toward the side which shows fewer knit rows, so in a finished piece side borders in the same stitch type should be considered.
Adding color changes in the ground requires altering the repeats.
Hand techniques may be used to modify ribs by cabling, racking, transferring stitches to the backing. When knitting again on empty needles, if you want eyelets, simply keep knitting. If not, hang the pull loop from the adjacent stitches on the opposite bed before resuming knitting.
Cable color placement must be reversed at the cable crossing.
Racked sequences are made along with stitch transfers.
To emboss other than vertical ribs the needle selection needs to be changed every 2 rows. This can be done manually, following a chart, or with programmed patterning whether with punchcard or electronic options.
Plaiting can produce 2 color variations without color separations.
When increasing stitches, moving the adjacent stitch onto the new needle, leaving it empty, will change the eyelet location a stitch away from the edge.
When moving stitches for decreases, lateral transfers may be made with multiple stitch transfer tools for different effects.
Transfer carriages can speed up the process.
To start the pattern one can begin with a cast on only on the ribber or back bed, or transfer non-selected stitches after the first preselection row on Brother as seen in most of my previous swatches, with 2 rows knitting on the backing alone, and 2 rows of the main color knitting on both beds. With either cast on, the preselection row is made toward the color changer with needles in work position on the main bed, so the knit carriage needs to be set to slip so as not to pick up unwanted loops on the top bed as it moves toward the color changer, and will remain set to slip both ways throughout the pieces.
As mentioned, the term Milano refers to ribs composing weft knit structures where one side of the fabric knits more rows than the other.
In half Milano, a single long stitch is created in the pattern color, in full Milano small stitches alternate with a row of longer stitches created when traveling back to the color changer.
The preselection start is determined by the type of long stitch, and how the repeat is programmed. I prefer to start my repeats with knit rows.
A half Milano swatch is begun with all stitches on the ribber bed, COR: the needle actions for each design row if patterning were on every needle are shown below. Designing may be easier to plan or chart on a template, followed by actions for each pattern design row with the second color. Half Milano on left, full Milano on right for use in 2- color-work 
Half Milano stitch formation on the left, full on the right Planning for a half Milano shape design outlined with added borders and with vertical columns at intervals in the alternate color: every 4th row is marked in yellow as the underlying template. A simple shape is charted out, marked with black cells, the pattern starts with a knit row. Preselection in slip stitch is made toward color changer, black pixels will pick up stitches moving to the right, slip top row moving to the left. Decreasing to maintain the dominant color shape is not necessary, while the border, in this case, is shaped by decreases made by transferring non-selected needles to the ribber before knitting with that color from left to right. Border cells are added immediately up and to the side of those planned for knitting on the previous row, their respective cells are outlined in green. Software programs make it easy to alter the repeats and add borders  if wanted
Actual knitting will indicate whether adjustments are needed in making the repeat continuous vertically or with some added striped ground only rows in between. I had not noticed a stitch hung up on a gatepeg, explaining the distortion in the row marked by yellow arrows, where the yarn was caught and pulled up. 

These techniques share some features with the category of double bed appliqué, where one bed knits the main fabric while the other creates the shapes, which are attached to the fabric as you knit. In the finished fabric the purl side is the right side, the ground may be created in a solid color or striped. Both shapes are knit at the same time, as opposed to performing the technique on a single bed. As usual, the color changers should be threaded so that yarns feed smoothly and do not cross. With simple shapes as in shadow lace, no punchcard may be necessary, while cards or electronic repeats simplify the steps and help prevent mistakes.
In Japanese machines, for each row in the charts 2 rows are knit in the background first on the ribber, followed by 2 rows in the shape color on the alternate bed.
Smooth yarns and contrasting colors that still allow identifying knit structures easily are best. There is a limit to the number of colors that may be knit at once. Beginning with hand techniques: it is good to chart out the design before tackling it, and with color changers limited to holding 4 colors, if planning several shapes, the sequences in the color changes may need to be plotted out ahead of knitting as well.
Purl loops are the tops of the stitches in the row immediately below the stitches on the needle on the opposite bed, marked in green, while sinker loops consist of the yarn that is between the stitches on the needles, marked in red. Hanging the purl loops will help to eliminate or reduce the size of the eyelets. Take care not to use the sinker loops between the stitches, marked in red.  In executing the fabric as a hand technique, the main bed is still set to slip in both directions, the ribber to knit every row
1. Knit 2 rows on the ribber alone
2. Bring needles to be worked in the pattern at the upper working position D or E, hang loops from ribber if there are increases if preferred, knit a row
3. Bring needles in pattern manually to D or E again, knit the second row of the appliqué
Repeat steps one and 2
In published directions color 1 usually refers to the ground color, which knits on the ribber only. Color 2 generally knits on the patterning bed as well. When most needles are in work on either bed, the tension for the yarn on that bed approaches the one used for that same yarn if it were being used single bed.
Punching all squares in 2 consecutive rows, or programming 2 all-pixel rows filled in completely across followed by two unpunched blank or all white pixel rows makes the process quicker. Punching or filling in single rows may be done as well, but requires elongation X2. Increases or decreases may be done on more than single stitches, and less frequently than with every pattern pass.
Fully fashioned shaping alters the edge of the appliques and places the eyelets in pattern, at or away from the edges. In Brother machines preselection of needles needs to be retained after any stitch manipulations.
Adding shapes with additional eyelets: practice shaping, keep notes, fully fashioned=FF  Begin with simple shapes, examining the quality of increases and decreases, whether single or multiple, eyelet formation.  Picking up from the row below before the next pass with the contrast color eliminates eyelets
picking up from row below at any point during knitting decreases in the number of stitches, in contrast, may be made by transferring down to the ribber prior to changing back to the ground color Simple increases or decreases are made by moving stitches laterally in either or both directions.  Increases may be made by moving contrast color stitches laterally, followed by the choice as to whether to fill in the empty needle or allow it to create an eyelet.   Fully fashioned increases or decreases are made by moving a stitch or a group of them to the adjacent needle/s to the left or the right and then taking the double stitches back to the original position, leaving a single empty needle for the planned eyelet formation. There should not be multiple needles with no stitches on them unless the goal is to expose a stripe of ground typically, in these exercises, there should be single empty needles after transfers, making certain proper needle selection for the pattern group is maintained Combining eyelets with lateral increases When transferring stitches, watch for any loops getting caught on gate pegs, as seen on the left below, increases and decreases may be pre-formed on more than single stitches

Planning a medallion: cyan cells represent transfers to the left, the magenta to the right. At the top of the single medallion, the stitches were transferred to the ribber prior to knitting with the same color once there was no needle preselection for it on the top bed.
Programming repeats to help track needle transfers as well: it is possible to start with a published repeat, though once the principle is understood, required markings for DIY become easier. Electronic machines leave one free in planning repeat width. In this test, a repeat from the Stitchworld pattern was used. In its built-in memory format, it will not work, the repeat needs to be altered. Each sequence of passes with the LC consists of 4 passes, followed by two rows knit with the KC. Two rows are added to each lace passes sequence, which will knit on the ribber only, in the contrasting color. Transfers to left and right are marked in cyan and magenta. The specific software used or machine model may require that the repeat be flipped horizontally prior to being knit, true on my 930. Markings on the left are for ribber actions and settings, those on the right for the main bed. K indicates that that bed will be slipping, K that it will knit. The first preselection row after the chosen cast on is from right to left with end needle selection canceled and the knit carriage already set to slip in both directions, with all required needles on the top bed in the B position.
Transfers are made prior to carriage passes made with the pattern color, in this case, white. If a transfer patterning row follows a white row on the ribber, extra white rows will appear on the striped ground seen in this test, where the ribber remained set to knit every row in both colors  To eliminate the extra white rows, the main bed stays set to slip every row, the ribber settings alternate. It is set to slip for two rows immediately after knitting with the red yarn, then will be reset and knits for 4 consecutive rows.  Transfers to create eyelets are made on selected needles on each of those two rows, always toward the carriage, even as the transfers themselves change directions as the angles of the shape decrease toward its center on the top half of the design. After the first transfer and the carriages travel to the right, a long float will be evident, will “disappear” on the return to the left. Patterning selection will reappear as the carriages return to the left. The color is not changed. The ribber is set to knit in both directions again, forming stitches on both beds for the first two rows, followed by a color change and knitting in the red, on the ribber only for 2 rows, completing a sequence of 4 knit rows before the ribber being set once more to slip.  For consistency, I changed the settings on it to slip before picking up the white, changed it again after preselection of lots of needles meant the top bed stitches needed to be knit on both beds again. The first proof of concept, observing choices: as with other samples, the first patterning row after all stitches are transferred to the ribber requires a choice as to whether to pick up from the row below or simply allow empty needles to pick up loops on the next pass, the choice throughout here, marked A. Reducing stitches may be done by transferring down to ribber, B, or lateral transfers, C. D marks the spot for a possible shape design shape. Arrows on the purl side point to the direction of transfers, cyan to left, magenta to the right  As with single bed lace, the first pass after transfers creates loops on empty needles, which here need to be kept in upper work, D position after transfers. For non Brother knitters, Brother positions are A, B, D, E, skipping C. Knitting over the loops on the next pass on that bed completes the stitch. This design is knit as continuous, the striping at the bottom is wrong because the red was not picked up after the first 2 rows knit in pattern with white,  most sequences for the remaining fabric are 4 passes with white in the feeder, followed by 2 in the red.  All eyelets here are reduced in size by picking up from the row below, all transfers for decreases are made laterally, the border is set to a width of 4 stitches, the pivot point for the repeat has been narrowed the differences at the edges of the shapes.  Many of the same principles may be applied to designs using tuck stitch settings, where the striping will appear vertically rather than horizontally

Origami inspired 2: more pleats and folds using ribber

Periodically I search out previous drafts, this post was started in September 2019. Drawn to folds in a variety of ways again, I am publishing it in progress with the intent of adding more information and related swatches.

Some previous posts with related topics and technique swatches:
origami-inspired pleats1, racked patterns Passap/Brother 2, ribber pleated fabrics, and some possible needle arrangements 3.
There are many considerations if long panels or wide ones are required when setting up repeats in addition to what happens at the edges of patterns in racking as one bed moves near or past the needles in work on the opposite bed. If something like a skirt is planned, the choice must be made as to which side of the knit is preferred, and the end stitches of each panel should be on the underside of the piece unless the join is a deliberate design feature. To achieve that, some panels may need to be wider than others. If the pleats are bulky and involve deep foldovers, panels may be attached to yokes to reduce bulk at the hips. If working from illustrations for pleats for another brand, the needle setups shown may need to be reversed, or, since many such fabrics are reversible if manually set up with no additional patterning on the Japanese machines knit bed or European true double bed they can be knit as illustrated. Lock settings for the Passap are given with the back lock first (ribber settings on Brother), then for the front bed lock (top, knit bed on Brother). Cast ons must be fairly tight so there is no flare at the bottom of the pleats. They usually start on a standard needle setting. Needle transfers are usually made after the cast-on is completed, sealing the stitches with one row of all knit stitches. Swatches should be a minimum of 100 stitches wide by 100 rows if the end goal is a gauge significant garment. All fabrics with texture may change in both appearance and gauge after a period of rest. Some shaping if needed may be obtained by tension changes, OOW needle arrangements on either or both beds, or stitch type within folds (ie adding fisherman, half fisherman, EON patterning, etc.)
Pleat formation on the double bed is “easy” because the pleats are formed “automatically” according to the needle arrangement on each bed. That is true if the resulting folds are created by stocking stitches in vertical bands. My goal is not to provide patterns. There are many well-written ones easily available.

How small can one go? A tiny pleat: It is easier to transfer stitches when the ribber is set to P (Passap handle up). Remember to return the setting to half-pitch before continuing. The pleat is reversible, shown on both sides, reminds me of shadow pleats racking by one position X3 at first, and then X 5 in each direction did not produce results worth the effort IMO, the result is subtle, the reverse side of the fabric is slightly stretched in the bottom photo. Here the fold is created by 2 stitches tucking for 2 consecutive, then knitting on the same needles for 2 rows on regularly spaced pairs of needles on either bed. Most knitting is on a single bed. A lacey series of eyelets begin to appear, and in some random racking at the top of the swatch, the possibility of developing a secondary pattern due to the combination of racking and tucking begins to show. The middle image is of the fabric slightly stretched.  Passap Brother: the ribber can do the stocking stitch background, every needle in work, carriage set to knit. The setup is the same as the Passap diagram. A repeat with 2 black rows of squares followed by 2 white can be programmed on the top bed. On every needle selected rows, pairs of needles will knit, on the white, no selection rows the same pairs of needles will tuck for 2 rows. Moving away from vertical ribs becomes significantly easier if one has a G carriage. The alternative option is to create geometric folds that require transferring between beds. Any of these fabrics are best knit in a yarn that has memory and can spring back. Yarns such as acrylic can be permanently flattened by pressing, resulting in loss of texture. A quick experiment: black cells represent knit stitches, blue purl ones The needle setups: after casting on, transfer for a stitch configuration based in this case, of blocks that are 5 stitches wide. A single needle on the opposite bed is used on each outside edge of all needles in work.  When there are no groups of stitches in work on both beds the pitch can be set to and remain on P, which also will make transfers easier, as needles will be point-to-point. The ratio used in the test was in multiples of 5. The groups were 5 stitches wide, 15 rows high, with all knit 10 rows in between the repeats. The fabric is shown first relaxed as immediately off the machine, then lightly steamed and stretched. The yarn is a 2/18 wool, far too thin for this use, and likely to flatten considerably with pressing. The close-up of the purl side offers a better view of the resulting folds The repeat, 10 stitches by 40 rows. More on Knit and purl blocks to create folding fabric_ “pleats”  Pleated, plaited shadow lace Pleated one color “shadow lace” in Slip stitch patterns with hand transferred stitches, double bed

A quick review of plaiting on Brother machines

Over time plying yarns and the resulting color distribution come into question, which often leads to discussions on plaiting.
The plaited knit can be reversible, traditionally the main color will dominate the knit side, the contrast the purl.
The two yarns are threaded in separate yarn masts, with the thicker yarn on the right.
Plaiting is sometimes used in bringing scratchy yarns such as lurex can be plaited with softer yarns so that the latter is worn closer to the body in the final garment.
One of my ancient swatches shows some variations in using 2 different colored fibers in three ways. It was tagged for display with myriad other assorted swatches on corkboards in my classroom, which were usually covered with a variety of illustrations of stitches and techniques covered in weekly classes and in response to recent trends. As always, effects vary dramatically depending on the choice of yarn color, fiber content, and thickness. Here the 2 yarns were fed through separate tension masts, and knit together plaiting with yarns swapped in feeders for reversible striped effect yarns wound together with yarn twister and used as a “single strand”  Striping created by reversing yarn positions in plaiting feeder Using the thread lace setting and plaiting feeder working in every needle rib screenshot_23A mock plaiting effect may also be obtained without a special feeder by locking the pattern on any all blank row, the standard yarn feeder with A and B yarn placement, and the fair isle setting. Results are not as consistent in color distribution.
True plaiting usually requires a special feeder unless the specific model km has a built-in option. Two yarns are used in the plaiting feeder. They pass by the needles in sequence. One yarn always passes first, and the other follows. The standard feeder that normally carries the 2 colors when knitting fair isle is replaced, so this technique may be used in fabrics using cam button combinations other than fair isle and thread lace. Looking into the plaiting feeder from above you will see a central hole that traditionally carries the “main yarn”, and a crescent-shaped opening that carries the second yarn, which will trail behind as the carriage moves across the knitting bed. The second yarn appears on the purl side of the fabric.
On days when lurex combination scratchy yarns, and in any situation where the fiber used is unpleasant if touching the skin, a softer yarn may be used and brought to the interior side of the piece for comfort. I once made a chenille sweater with traditional cap sleeves that refused to knit to gauge. Adding matching wooly nylon and knitting it with the chenille solved the problem permanently and stabilized the knit.
The contrasting color can provide a pleasant effect when fold-over collars, cuffs, etc. are part of the garment, and so on.
Brother plaiting feeders: The central hole holds the main yarn and the crescent-shaped hole behind it holds the second yarn. As the carriage moves across the row, the yarn in the crescent-shaped hole trails behind the other yarn and is always the second yarn picked up by the needles, showing on the purl side of your knit.
Be aware if considering purchasing one that other parts appear on eBay and other sale sites under this name, but are not the specific accessory. The following illustrations and directions are from Brother pubs easily found for free download.
For use on the main bed, images from the KnitKing 893 manual: If your sinker plate has rubber wheels, check them and move them to the proper position if needed. Canceling end needle selection applies in any situation and is used in tuck or slip stitch settings if there are needles out of work on the main bed for any reason to maintain proper patterning in needles in work. Electronic knitters have the KCII option in the change knob.
For use on the ribber:
More random, ancient swatches: stocking stitch using equal-weight yarns in a single bed tuck stitch

double bed every needle rib tuck stitch using the same pattern repeat a racked sample Shadow lace Pleated pattern When working on large pieces, the yarn in the front feeder may slip out.
This is one option to prevent that when the ribber is in use At one point, I produced several circular sweaters using equal-weight yarns to obtain the reversible 2-color look. I had more than one feeder, so I used a dab of glue in the slit below the yellow arrow The drawback to doing that is that the yarn cannot then be easily slid in and out of its position but rather has to be dropped through the remaining hole using a double eye needle.

These illustrations are from a Brother manual for the 860 punchcard machine, an idea for working intarsia.

Racking on EON rib: some considerations

Manuals can sometimes make my head hurt, and as a result, I often rely on previous experience which in turn can lead to assumptions that may require clarification, even in my own mind.
A question came up on Ravelry about racked ribs on every other needle. My instinctive answer was that racking would need to happen by 2 full numbers at a time for the proper swing to occur. Here is an attempt to explain some of what happens, and why that is not always true.
To start with, manuals usually have the knitter start with the carriages on the right-hand side of the machine, perhaps to prepare them for fabrics that will need to travel to and from the left if the color changer is in use (“Japanese” machines). If the latter is not, there is no reason not to begin knitting from whichever side you prefer. Then we get to 3 circular rows. The third row is not needed, it gives floats on one side of the rib that may or may not be noticeable depending on which side of the knit is the public side. If 2 circular rows or a racked cast-on is used, that may set off the start of patterning in the wrong direction from that published.
The usual depiction of the zig-zag row with the cast-on-comb in place on the machine is this The intent when knitting ribbing is not to have needles point to point, smashing into each other as one travels from side to side. On every needle rib, the Pitch lever on P will set just that up, H for half-pitch will place needles so they move smoothly halfway between those on the opposite bed. On every other needle rib, the P position will set up needles in the center of the spot left empty by a needle out of work on the alternate knitting bed. In racking, as the ribber moves, its stitches will align (usually) to the right or left in turn of stitches on the main bed creating a sort of crossed texture. If the needle setup remains as above, and racking is performed one step to right or left followed by another in the opposite direction to the starting position, the stitches on the main bed remain in the same space, and there may be movement between the purl columns, but not across them. For a single-position racking to occur the needles on the ribber need to be brought closer to the stitches on the opposite bed. One way to achieve that is to set the ribber for half-pitch. That will bring its stitches off-center and more to one side than the other of the space on the opposite bed. The zig-zag will lean slightly to one side The next step is to ensure that as racking begins, you are not moving stitches back into the same empty space on the opposite bed, but rather crossing into an adjacent one If that is understood then one can make the choice of moving left or right and be off and running in the pattern, aside from the starting side or some of the other directions given in patterns or manuals. Cam buttons and patterning may be introduced as well. This is how a row of knitting might appear after racking. The difference between the top and bottom of my test swatch is that the bottom was knit in half-pitch, using 2 single alternating number positions (ie. 5,4,5,4),  the top was knit in P setting, racking by 2 number positions (ie. 5,7,5,7) in each direction. One row was knit between movements. Both carriages were set to simply knit. This page from the Ribber Techniques book shows fabrics knit on EON, adding tuck cam buttons into the mix and slightly different needle arrangements, varying the look of the finished knitting. Most Brother racking patterns are accompanied by diagrams such as the one included above. They are shorthand for what is happening on both beds. If the knit starting side is different than the one recommended, as long the necessary movement directed against the fixed stitches on the main bed is recognized, the starting point can be chosen to be on either side of the main bed needles (ie. starting on row 3 on left, above blue line of the chart as opposed to row 1). If multiple side-by-side stitches are in work on the ribber, the half-pitch setting applies as well. When tucking is added, for increased stretch, it may be necessary to compensate for the width of the resulting fabric by casting-on on every needle and then transferring in the desired configuration between the beds. Transferring is easier done in full pitch with a return to half-pitch prior to continuing to knit. The bind-off is likely to require considerations for an added stretch as well. Slip stitch narrows the fabric. Such adjustments are usually worked out in test swatches.
Using the half-pitch in EON brings the needles on the ribber closer to those on the main bed, which in turn may have an effect on yarn weight use when building up loops in hooks ie in fisherman or half-fisherman rib variations. Sequential racking ie. 5, 6, 7, 6, 5, 4, 3, etc will not produce crossed stitches with single position shifts on EON. This attempts to imagine where actual crossings would occur, every 2-position shifts in either direction. The starting point for cast-on may also require a change in position, based on the number of positions available; for example, Brother has 10, and Passap has 6. By the way, the racking position indicators are slightly different in the Brother standard vs. the Brother bulky machines

Racking mechanical problem and possible repair saga

I enjoy the technical aspects and structures of knit fabric, learned to do simple, common minor repairs in a studio where there were not technicians during lab hours or even studio hours. That said, I had a broken knit carriage that was going to be my source for learning to work with its inner guts that never made it to any useful reassembly in spite of the passage of a couple of decades. I have a lot of hesitation in taking equipment apart, though out of necessity and with the help of online videos and information I have been able to go increasingly further with more confidence. Still saving carriages full of springs and “things” for someone else 😉

Over the years I have not used my KR850 ribber frequently. Last year at some point I produced a collection of racked, ribbed 3D effect scarves, giving it a major work out. I traditionally kept my ribber off my Brother machines, used my Passap for double bed and DBJ, and my line of accessories for sale was often knit single bed on my standard or bulky machines. As a result, I rarely needed to adjust the ribber bed position relative to pitch. I had purchased the ribber used.
As I have returned to knitting more frequently of late and wanted to expand posts that included racking I found suddenly the first movement upon reversing racking direction failed, requiring 2 full turns of the handle before advancing to the next position. Not too long after the pitch lever was not moving properly as well. The operation and service manuals for the ribber had not provided much advice, nor could I find any helpful information online. I highlighted pertinent areas with color in the images below. From the service manual: I asked on Ravelry for advice or shared experiences. A possible culprit was suggested to me, and I was pointed toward the parts manual, where I was faced with this, which at first seemed pretty daunting

When I tried to turn the screws marked in red I found they were loose. After I  took apart the racking handle, braving far more disassembly than turned out to be needed, housing little screws and washers in separate small plastic containers along with their comrade larger parts, I found perhaps I could have reduced the effort considerably. I did not take photos during the process, as I was not brimming with confidence in the result. Enlarging a portion of the above helped me understand how parts related to each other a bit better.

The rectangular piece (red) was loose inside the machine. Removing # 57 is a necessity in order to get at the location for reinsertion of #10 in the slot under #9, to be held in turn by the screws #11. I marked critical areas with colored arrows in sequential photos It really may not have been necessary to even remove the bracket lever. The #10 piece of metal was loose inside the machine, might simply have fallen out if I had turned the bed on its side and given it a mild shake after removing #57. This is with the piece in question in its housing where it belongs (white arrow), shown in relation to the needle retainer bar (black arrow) and screws marked with red arrows that hold it in place. The piece is obviously thinner than the space it lives in, so for screws to anchor it properly, a flathead screwdriver or other improvised tool needs to be inserted under it, lifting it into position and holding it in place with its holes lined up with outside of bed so screws can grip it and be tightened properly. My racking handle and pitch lever seem to be working properly once more. I had hours of intimacy with my ribber, it has now been thoroughly cleaned and oiled and has all its screws no longer off or loose, we are far better acquainted. No regrets, but the “repair” as illustrated above would have taken a matter of minutes.

A racking tale: Passap/Brother 3

While browsing through  E6 Passap model magazines I was intrigued by the pattern in this edition with models for children shown below on the right The instructions for the stitch pattern include a knitting technique to be programmed via a card reader. The results of entering it would be altering the pattern internally with the goal of providing racking directions on the console with each pass of the locks. The Duo has a 40 stitch wide punchcard capacity while the black and white squares repeat is 14 stitches wide, so not for use on it. DIY techniques for the E6 are a whole other topic, so let us analyze the Duo instructions. Keep in mind that in Passap the front bed moves when racking, it is the patterning bed. In Brother the “front bed” is actually the ribber, while patterning occurs on the top bed, so needle arrangements will be reversed. Brother has only needles, so pusher selection is not pertinent in diagrams. The out-of-work needle positions on the back bed need to be matched in the same arrangement and location on the Brother ribber. Transfers are made more easily be made to the knit bed after completing the cast on and the first KC preselection row is knit. Be sure to return any preselected needles to their original position. If the needle pitch on the ribber is changed to P to make the transfers easier, remember to change it back to H before proceeding, this is a fabric with every needle configuration on both beds. Translating Duo directions to black and white squares in order to develop a repeat for use on Brother: N/N is easy. The Duo is using buttons on the front bed and selection in response to their arrow setting to alter and progress through the pattern. The setup is with 7 needles up, 7 down, creating a 14 stitch repeat. BX on Duo (LX with patterning on front bed E6) is the equivalent of slip setting on Brother. No arrow keys, Passap on N, everything knits. Brother equivalent is a row of black squares (or punched holes if applicable) for each row on the N/N knit setting. BX <– will reverse the needle selection from whatever it was immediately before the previous rows of N/N, and remain there for the full racking sequence. After the first 32-row repeat is completed, at the end of the 12 racked rows, there will then be 4 all knit rows between racking sequences, two knit rows at the top would match 2 rows knit at the start. Once again, the BX<-for one row sets up the alternate blocks of racking. I chose to start my repeat with the 930 with a cast on in racking position 10. The chart shows racking positions on each row, reversing direction after having reached #4. E6 knitters may use the same repeat, matching the Duo racking starting on 3 left to 3 right and back

The repeat viewed tiled:  My samples actually produced a mirror image of the repeat, this is how that would have appeared flipped horizontally in the magazine
I first used a blue Italian import 2/14 wool, which knit well, but I had a hard time seeing the stitches being formed on each bed and missed a couple of dropped ones. The 2/24 acrylic to its right knit resulted in occasionally dropped stitches that were actually solved by swapping out the needle retaining bar. A sample in the yellow 2/13 wool used in previous posts simply would not stay on the ribber well for the number of rows in this pattern.
After swapping out the needle retainer bar,  knitting went smoothly. On the right in the photos below, the same racking sequences and needles out of work on the ribber are used, but the knit carriage was not set to slip, so essentially, every stitch on every row on the top bed was being knit. In addition to needle preselection, one should also check the type of stitches actually being formed. One of the disadvantages to knitting ribber fabrics is that several inches may be produced before one can actually evaluate the pattern being knit by peeking between the beds. I will have to revisit a previous post with some interesting racked textures that now appear to me to be related to this one,  beginning with this one, from a publication for the dubied machine this case the back bed knits every stitch, every row, a single function on all needles. If produced in the illustrated orientation, the racking bed (ribber) switches from knitting to slipping stitches. In Japanese machines, the ribber carriage cams must be switched manually from slip to knit to reproduce the pattern. To begin with, the repeat is rotated so it is the knit bed that will have the needle out of work selection was hesitant to rack four positions after only 3 rows of all knit, so I began with 4 rows knit, 4 rows slipped, with needles set up as shown above. The racking happens after every 8 rows by 4 positions, and the first all needle preselection row at the top of each repeat is an easy marker for moving the ribber. Pitch is in H, the top bed can be moved even though all needles are selected because the ribber needles are in B position, and there are no potential jams. I chose to start at 10 and move from that to 6 and back. Solid black and white lines can be used, since the needle selection on the top bed is fixed and altered by movements of the beds in relation to each other, not the programmed pattern itself. The repeat with main bed set to slip <– –>, the ribber set  to N/N, and the resulting swatch:

Using the same yarn, reducing the tension a bit, and knitting 3 rows, slipping 3 rows, racking 10 to 6, and back to 10. A partial view of my needle bed: All needles used in my swatch, I began the stitch transfers down onto the ribber needles on the far left, continuing across the knit bed. As end stitches knit on the ribber alone, a small edge weight may be required on that side. As stitches on the main bed are not worked in the slip stitch rows, they become elongated. Racking by 4 positions is not possible unless there is enough fabric so as not to pull so much that stitches will not knit off. If the yarn does not have some “give” that can make the changes in position harder, some yarns may break easily. The long stitches: After the needles are preselected for the next row of all knit, rack to the next position; the long stitches will then lean to one side or the other The resulting swatch, shown on both sides: The texture becomes more pronounced after the swatch rests. If acrylic is used, remember not to press the knit. An attempt to identify stitch actions: This is the swatch knit changing ribber settings to and from slip <– –> to N/N on appropriate rows.  I found the method above far simpler Coincidentally this morning a Duo pattern using a different setup was shown in Ravelry, and I was asked whether producing the same on Brother might have any advantages.  The Duo results, shown on a project page, are very similar to the above. The advantage in my opinion of using this method on Brother machines is that there is no need to change lock or carriage settings, and racking when the preselection for the next knit row first appears creates an easy marker for when to move from the previous racking position to the next. The Brother repeat (KCI on electronics is OK even though there are needles out of work on the knit bed) Racking is from position 10 to 6 and back just as in the previous blue swatch, after the first preselection row at the start of  the following repeat sequence. I began the stitch transfers down onto the ribber needles on the far left, continuing across the knit bed. The final look will vary with the choice of yarn and its color. Both swatch sides.If for some reason horizontal direction matters simply cast on with racking position on 6, and continue to and from there to 10 and back. Below is a horizontal flip of the same swatch image, a way to quickly decide whether doing so might be preferred.

Racked patterns 5: Passap/Brother 2

I have been asked whether this particular fabric discussed in the post could be produced on the Passap. The only way to find out is to try it. The lesson already learned: use a yarn that is crisp or capable of retaining memory for maximum effect. Here the swatch is knit in a 3/14 cotton. To start with, racking was from position 0 to 6 and back. Racking every 2 rows at the bottom of the sample, every row at its topNow adding needles out of work with the expectation of folds at approximate center of each foldThis was my set up, after planning the repeat and transferring a couple of stitches on each end to the back bed for better side edges Racking started in center position 0, then swung to 3 left, to 3 right, ending on 0. I long ago got frustrated with the Passap numbering, marked the racking positions with a permanent marker from 0 on the right to 6 on the left. The knit result is definitely a rolling fabric, though a bit less so than the Brother sample which was able to move across more racking positions Reviewing some racking facts: several posts previously written that include information for racking designs on both brands

Brother racking controls: the handle, racking indicator, and pitch lever There are ample illustrations including from Brother Ribber Techniques Book in previous posts on procedural steps. Passap: racking handle is up for full pitch (point to point), down for half-pitch. It is turned one full rotation for each unit/ number change in ranking positions. Partial rotations may be suggested when some of its accessories ie their transfer carriage are used. As stated, Brother has 10 positions, Passap only 6. Passap E6 manual shows racking patterns possible with console built-in designs on pp. 118, 119, 120, 121, techniques used in racking patterns number 257-272. The console gives prompts for the direction in racking sequences. Self-programmed designs would need a separate knitting technique entered into the console as an additional “design”. This can be done with a card reader combined with a pattern download from a computer. Programs that automated the function to any degree are no longer on the market. Typically, in published patterns for either brand, if the starting point for the racking sequence is important, it will be given along with the frequency of movements such as in this design from the Duo 80 bookProgramming the front bed on Passap or main bed on Brother with tuck or slip selections begins to enter far greater common ground. Decades ago my advanced knitting curriculum included Passap weekend workshops in addition to Brother course classroom and studio hours. I spent a lot of time exploring techniques, often my manual includes scribbled notes. Manual guidelines for E6 patterning, beginning with advice for knitting them 

I have to admit I cannot always now decipher some of my note-taking or my own handwriting. The additional confusion that comes into work in cross-brand translations is the fact that some E6 techniques may only be used as programmed by the factory, others may be “combined with stitch patterns”. Getting it down to black and white squares when stitch patterns in E6 and are to be translated for other KM brands is a bit more complex, easier done from the Duo 80 instructions when an E 6 is not available for test knitting. The Duo manual is low on swatch and pattern assortment, but a small book, available online can provide inspiration for many textures, the Passap system’s particular strength. Some Duo symbols and their meaning
Many designs are based on one or both beds having needles out of work. Transferring stitches from one bed to the other can be done from needle diagrams on the Duo 80 and punchcard machines after the cast on row is closed. If the specific technique in the E6 offers a pusher selection after the first SX/GX row (262,264, 265, 269, 270, 282) transfer stitches then with locks on left, otherwise, transfer after the second SX/GX pass to the right (257,258,259). After the pattern is set up in E6 place all the pushers in rest position completely out of work.
Pushers corresponding to needles out of work on the back bed need to be in the back rail so as not to cause mispatterning if arrow keys are used. In Japanese electronics, transfers can be made after the first KC pass, making certain emptied needles are placed completely out of work. Set up the knit bed first, so alignment relationships are correct for out of work selections on both beds.
As in any ribber pattern, if the major part of the piece is being knit single bed, the tension will need to be adjusted to closer to that used in stocking stitch for the same yarn. Passap knitters have the added option of changing stripper in use to another color.
When designing your own patterns and starting the movements on either side of the machine, it will take some sorting out as to what arrangement of needles in work is best on the Passap back bed or Brother ribber is best for side edges as one bed moves beyond the last stitch in work on the knit bed. There should be no stitches on it without stitches behind them as the racked stitches travel from each side to the other if the goal is pieces that will be seamed ie. front and back of a sweater.
The E6 console may not always give the proper selection for needle set up for the front bed as seen in one of my swatches. There are never instructions for the back bed needle or pusher positions. Those need to be hand selected based on diagrams after the front bed is set up, and following the diagrams provided with each technique to produce the specific fabric illustrated. That can be disregarded in one’s experiments with needle arrangement and lock settings and how they relate to the movement in the racked stitches.
If one needs to stop the process at any point it is a good idea to devise a method of keeping track of where the stop occurred and whether a racking movement has taken place yet or not. Forming personal, consistent habits is also useful, ie. I find when racking with color changes I rack before I change the color consistently. Racking when using multiple colors often happens at the end of the color change sequence ie. 2 colors, rack after 4 rows. A bit more attention needs to happen when racking is for only a few positions. I tend to start mine on the far right at 0, so I can move the one or 2 steps and am stopped by the machine on my return, giving me an error margin on only one side.
A few Duo/Passap comparisons

Swatches: this E6 design introduces needles out of work. The E6 swatch in color below on the far left has a slightly different needle arrangement than the DUO one to its right. Technique #257 has a * beside it, which usually indicates the repeat must be altered to produce the fabric. 120 is the page on which the swatch photo appears Altered designs are listed on pp. 129-131of the E6 pattern book for all stitch types. 

The original on the left is mirrored, the selection is fixed, the height is multiplied X 6. The lengthening does not influence the design, it tells the console how many swings in each direction are planned. The console, in turn, gives visual and sound prompts for each racking movement, in this instance,  by one full turn clockwise. The prompts often start the pattern in the center 0, and begin and end with half a sequence.  The front bed is set to slip stitch, so black squares knit. Both beds will knit every needle/pusher in work throughout. After first preselection row on either brand needles and pushers in non selected areas need to be put out of work, accomplished by transferring them to the opposite bed. The design process is the same as having a fixed row on a punchcard machine, with a single selection being repeated over and over. The racking position indicator on the duo shows the start of the pattern at 0 position, Brother equivalent = 10. In the duomatic the carriage is set for plain knitting, no patterning is required. The needle out of work selection is different than the E6 sample, but the racking sequence is the same. Brother options: fixed needle selection if the fabric is created fully as a hand technique does not require any programming. Electronics could be used with the repeat drawn X6 in height so that the racking direction is reversed after the first sequence is completed and the return to row 1 of the repeat is preselected. Machines that allow for it can have info added to memo windows or even on mylars to help accuracy in long pieces. Punchcard machines could punch a single row on #1 for accurate needle selection if it falls within the 24 stitch limits or hand-select them, mark racking numbers in repeat, and go on from there.  My sample was knit in a tightly twisted cotton, and when off the machine had an interesting and unexpected fold 3Dquality

The setup is essentially the same, with white squares representing needles and pushers that need to be out of work. Tech 258 uses LX (slip) on the front bed, back bed si set to N. The duomatic pattern has a different OOW needle arrangement, the front lock is also set to tuck =  FX (E6=KX), adding another layer of texture and complexity. Needles are also out of work on the back bed.

E6000 264* is used both as a pattern and a technique number uses the X6 as well for accompanying prompts. Needle/pusher selection is for 3 in work and 9 out of work for 2 rows, then reversing it for to 9 in work, 2 out of work for 2 rows, thus accommodating the alternating color change. The Duo on the front bed performs a similar selection with the BX <– arrow key, racking is every 4 rows in both. It takes 24 rows to reach the full racking position reversal. These were the pusher selections, each repeated X 2, creating the wrong fabricWhat is knitting in terms of black and white squares if one continues:this repeat is what is required to match the technique diagramAfter the first row of pusher selection transfer 3 stitches on either side of the center 3 in each group of 9 to the back bed. This shows the proper selection, each is repeated twiceI continued to knit with plain knitting on the back bed for proof of concept, every other needle selection, and slip (BX) stitch <– –> there would compress the “wave” since half as many rows would then be knit on that bed in each color. As always, forgetting to set the lock/carriage to slip will result in knit stripes as seen on the right of my sideways swatchBelow the pattern alternates blocks of 5 black squares, 5 white, color changing every 2 rows and reversing racking direction after every 24 rows. The full repeat is 48 rows. If rows knit in the zig-zag are counted, they amount to 12 because each color slips it is not knitting for 2 rows. Note that to achieve the color reversal at the halfway point of the repeat the same color (2) knits for 4 rows, at the top of the repeat color 1 does the same.

Below tuck patterning is introduced in both beds. The front bed is knitting tuck on every other needle for 2 rows each,  easy to reproduce on Brother AX<– on the back bed will knit when pushers are up for 2 rows, tuck on the same needles when they are selected down, also for 2 rows. Brother knitters could try to set the ribber carriage to tuck in one direction only, or simply set it to knit every row

Though tech 264 states it may not be combined with a stitch pattern, I programmed built-in # 1002 X 6 in height, back bed set to slip (BX<–) every 2 rows. Racking occurs every 4.  Full repeat is 48 rows. Back bed pushers should be in work so they stay inside the edge from knit stitches on the front bed. This was a quick test. The knit side is unremarkable, the mess on the left edge on the upper right of the top photo is because I began with 2 needles in work on the back bed like in the illustration above. As I racked counterclockwise the stitches on them kept pulling away from the side edge (back bed, left). The technique continues to give racking prompts as written by the factory, so none would exist for the rows with no racking in the pattern
Back to acrylic yarn, light color for more visibility creative yarn snag on the left midway, full swing movement is shown, each is 48 rows in height. As always it helps to check whether stitches are obliging by staying on the needle bed. The top half of the swatch is shown.
In turn, I programmed # 1000 X 6 in height but pusher selection was all up for one row, one down. I left it alone, and lastly, worked with pusher selection on the back bed, BX <–. Patterning advances a fixed repeat every row or every other, determined by original hand-selected up for selection and down above rail for out of selection. The front lock is left on N (disregard front for setting it to LX) there is a whole other world of possibilities, while the console racking sequences can be used from built-in techniques.  Any ribber needle selection on Brother other than the use of lili buttons would have to be done manually.

The range of fabrics with programming additional patterns in tuck, slip, or combinations thereof along with needles in and out of work on the either or both beds increases the possibilities for fabrics with texture and dimension exponentially. 

Fisherman_ English tuck stitch rib 1_ checks patterns_ Brother, Passap

More than 6 years ago I produced a series of scarves that were double-sided, reversible, and were considered “manly” by some of the customers at my shows. Some were one color, some in 2. I found an early post with no clear instructions for them, but with this image and that of a punchcard marked for a racking pattern (given below). Coincidentally the question of checkerboard rib knit patterns came to light in a forum, and I found myself reviewing the technique, with part of the intent to reproduce this fabric. I have, over the years, been terrible at keeping good notes (if any). At times what I was working on was so “obvious” I had confidence I could rely on my memory. At others my attitude once the problems were worked out and a limited one of a kind series was produced, was that I was “done” with that particular fabric. Now here I am, years later, with a mystery pattern on my hands and a time-consuming quest, wishing I had documentation for how on earth I achieved it

Definitely not “there” yet:

Early translations from the Japanese or German manuals did not always communicate clearly the meaning of symbols or actions required to be taken by the knitter. A bit clearer meaning may be gleaned from these instructions in Brother Punchcard Pattern Volume 5. The hatch marks on the racking symbol indicate the number of pitches the ribber is moved in either direction. The number of stitches moved corresponds to the number of needles in work on the ribber. Recommended settings for English rib also known as half-cardigan, royal rib, or pearl-stitch, with no patterning or racking, the beds may be reversed. It is a 2-row repeat. One row is tucking on the main bed on every needle in one direction,  knitting on every needle in the same bed upon return to the starting side. The opposite bed knits every row. There is one textured round followed by one of 1X1 ribbing. It is not a balanced structure, looks different on each side. Variure denotes fabrics wherein the same bed is tucked for 2, 3, or even 4 rows followed by one or 2 rows of rib knitting every needle on both beds. The tucking bed may also be set up with needles out of work and with added racking as well.
In fisherman’s rib, the settings are for a tubular tuck, with opposite tuck buttons set in the carriages. While a bed tucks on every needle, the opposite bed knits every needle, reversing the process on the return row. It is also a two-row repeat and referred to as full-cardigan stitch or polka rib.
It has the same appearance on both sides and does not contain any rows in all rib. An additional illustration of both The recommended Brother ribber’s “needle rule”.More tuck rib variations may be found in posts on interlock 1, and 2.
Adjustments to the needle rule may be needed depending on the fabric. If only one bed is knitting while the other is tucking, having the first and the last needle in work on the knitting bed. In English (aka half fisherman’s rib) only one (either) bed tucks.  Directions marked with green #6 on left are from the Brother Ribber techniques. The remaining images are for the single-color racked checkerboard pattern from Brother Punchcard Pattern book #5. No pattern card is involved, every other needle arrangement suggested on the right accommodates slightly thicker yarns. A half-pitch setting is used.

In the above instance, the main bed is not performing any patterning function, it is knitting on every needle in the work position. On a punch card machine, a card may be used to track racking positions. With the carriage set as usual for patterning and needle selection but with no cam buttons pushed in, the main bed will continue to knit stocking stitch. No rows are punched, and the numbers on the card in the colored columns indicate the racking position for corresponding rows. The “card” on the left is designed to match racking positions and carriage travel directions (colored arrows) to mirror those in the publications. Since a 36-row minimum is recommended for continuous punchcard use, the “card” on the right has added a 4-row segment for each segment of racking directions. The full repeat is now 40 rows rather than 32 in height. The numbered columns on the far right are as they would appear on standard blank Brother punchcards. The number one is at the level of the first visible row while the card reader drum is actually selecting the first design row. End needle selection is canceled (KCII on electronics). The first move as indicated by arrows is to the right, so the first row is preselected from right to left. The card is then set to advance normally and released. If any errors are made treat card adjustments as you would in any other fabric.

Adding main bed needle selection for selective patterning: the actual punchcard here includes annotated changes in racking sequences from 5/4 pitch positions at its start to 5/6 racking positions for the top half of the completed repeat on its left side. It may be used as-is or set to double length either for use with a single color or combined with color changes every 2 rows.

The card as punched may be used in many ways. In past experiments, I have shown that not changing the racking pitch for a single row while keeping the two alternating pitches constant created scale-like textures rather than checkerboard patterns

here again for a 16-row sequence

On fabrics with racking enlarge the stitch size by 1/2 to one full number to accommodate the stretch needed in racking the stitches.
Color changes: fabrics made in full fisherman rib are reversible, while those in half fisherman are not. In full fisherman rib in order to knit a specific color, that color must be knit for two rows and tucked for 2 rows alternately. In Passap AX with pushers and arrow keys must be used, in Brother, ribber needles would need to be hand-selected to the proper position on every row. 
The yarns used should be soft and have some stretch. Every other needle patterning may be used with slightly thicker yarns.
Racking in the same pairs of pitches ie. 4-5, 4-5 with no added actions taken, produces vertical columns, akin to results in any fabric that repeats the same functions in the same locations on the needle bed

I knit my first “checks” sample on a 930 electronic programming a single repeat to match the card used double length. The goal: the check sample pictured in punchcard pattern book 5 

In programs or machines that allow for memos that correspond to design rows for each repeat, enter the racking pitch number beginning with design row number 1, and continue to 32 or more as needed. The racking sequence is changed at the halfway point of the full repeat.

Added experiments: using the same electronic repeat above, here I worked *20 rows racking every row between positions 4 and 5. One row was then knit on all stitches on the top bed** (I pushed needles out manually rather than changing cam settings), repeated * to**. The fabric reminds me of racked herringbone, the “checkers” are distorted Changing color every 2 rows shows the same lean in the fabric. I have had intermittent problems with my ribber, stitches begin to simply not be picked up by the main bed and are dropped for no apparent reason A very different fabric is created using the repeat and instructions below*Knit 2 rows, rack 1 pitch to left; knit 2 rows, rack 1 pitch to right to RC 20 (or preferred row count); knit 1 row continuing in pattern to the opposite side without racking**. Repeat * to**. One repeat of the 2 sequences is 42 rows in height. At row 1 of each new (here 21 rows) sequence, the carriage starts on the opposite side Changing colors every 2 rows is possible. The racking will begin with the carriages on alternate sides of the machine after the single-row knit without racking. In segment 1 racking occurs on the left, color changer side, and in segment 2 racking occurs on the right, opposite the color changer. 

“Full” fisherman rib with patterning on both beds: on Passap the back bed is capable of many more patterning choices than in Japanese machines, and strippers help hold loops in place on the needle beds. The Passap “needle rule” places the first needle in work on the front bed, and the last on the back bed. This is also variable depending on the fabric being knitted. Using the repeat

tech 129: (black square tuck for single row) on the front bed. Set up back bed after prep rows, making sure pushers are in the same work/rest position as on the front bed *Knit 2 rows, rack to left, knit 2 rows, rack to right to preferred row count ie RC 20; knit 1 row still in the pattern, without racking**. Repeat * to**. One repeat of the 2 sequences is 42 rows in height. The resulting pattern is reversible.” This swatch was knit with the bottom 3 blocks using 6X6, both arrow keys on the back lock, and N in front. The back bed pusher setup is doing the patterning. The top 3 blocks are set to pattern selection on both beds, using AX, arrow keys, and KX on the front lock. Using technique 130 will double the height of the repeat, working each row twice.

On Brother, the second bed selected needles will face tucking needles on the main bed. This creates a knit stitch on one bed, holding down the tuck loops on the other, allowing for side-by-side tuck loops on opposing beds. Such selections would need to be made on the ribber manually. Both beds are set to tuck, both arrow keys. The needles on the ribber immediately below the ones tucked on the main bed are brought to the E position and face the tuck needles on the main bed, while its non-selected needles will tuck. Rack before pushing those needles (black dots) that will be knit up to the E position. The Brother settings for full fisherman suggested in their Ribber Techniques Book and manuals produce a “circular” tuck stitch, with each bed tucking and alternately knitting on all stitches in opposite directions, so the cam button setup is different than when one is planning textures in varied patterns It is also possible to produce “checks” without any racking at all. On the Passap, this sample was produced eliminating racking completely. The front lock was set to knit throughout / N, the back lock alone did the work. Pushers were selected 6 up, 6 down, the back lock set to AX with left arrow key for even multiple rows divisible by 4. I used 24-32 to get a sense of scale. The arrow key was canceled for the next 2 rows AX 0 to switch the pushers.  The working repeat became *32 rows 6X6, left arrow key, 2 rows AX 0*with the front bed programmed

Here the front bed is programmed for the repeat below, technique 130 (black squares tuck for 2 rows After the initial prep on the front of the bed, prior to knitting the first pattern row, pushers were manually selected on the back bed to match the pusher work/rest position selection on the front bed. Their position will change as the back lock moves to the left. After 12 rows, the arrow key was canceled for the next 2 rows to AX 0 to switch the pushers. The working repeat became *12 rows AX, left arrow key,  2 rows AX 0* with the front bed programmed, and its lock set to KX. The back bed produces a “checkerboard”, the front bed produces checks as well, but in a vertical alignment

A similar half-fisherman (only one-bed tucking) fabric may be produced on Brother machines by automating patterning and switching “beds”. The main bed is set to tuck in both directions, the ribber is set to knit throughout. My sample was pretty much a disaster at the start. After trying different carriages, switching out needle retainer bars on the main bed, checking alignment, and every trick I could think of I was rewarded with stitches simply not being picked up at intervals by the main bed. Time for a break for both the operator and the machine.  

a bit more success:

Below is my electronic repeat, 12 stitches by 56 rows in height. It is intended to mimic the work done by the pushers on the Passap. Alternate groups of 6 stitches will knit (black squares) or tuck (white squares) for 2 consecutive rows. At the center and the top of the full repeat, the two extra rows of squares result in alternate groups of stitches tucking or knitting for 4 rows, contributing to the shift in the color and texture of the checks.
Passap specials: the idea of hand-selecting needles every row while watching multiple loops tucking on both beds and even adding racking is far too daunting to my mind. Highly textured patterns are far more easily produced in machines that allow for a greater range of patterning on both beds.  To review, E6000 tuck settings:
N, EX: same on both locks, may be used without pushers or console
KX and AX: tuck in both directions
OX and DX: tubular tuck. FB: tucks right to left, free pass left to right, BB is opposite
The FX setting is incorporated into several techniques used with KX, 104, 105, 112, 113, 167, 259, and 260. Some techniques for adding back lock settings are 106, 114,145, 158, 167, 168, and 190. Techniques 259, 260, 269, and 270 use racking; 200, and 212 require manual changing of arrow keys; 284 uses the U100 transfer carriage in combination with fisherman rib for an embossed effect.
Using FX settings with pushers full fisherman rib can be combined with full needle rib or half fisherman rib on the opposite bed.

Technique 167: use FX/KX

Front bed pushers are always selected up from right to left by the console independent of pattern, so they will knit. Set up pushers on the back bed in the pattern after the first row of the pattern, and make certain they are in the opposite arrangement of work/rest positions on the front bed. EX knits on all needles from left to right. Black squares represent knit stitches and white tuck ones. Making lock changes at the start of the repeat: knit 14 rows,* Knit 2 rows FX <–/KX, followed by 12 rows FX 0/KX** Repeat* to ** One full repeat of the 2 sequences is 28 rows. The original BW building block is 6 stitches wide, 7 rows high, pairs of each form the unit used to form the larger repeat blocks

My chart for my full working repeat test sample: dots represent pushers, green highlights rows with lock changes for pusher reversal. The latter are made here on RC13 and 14 rather than RC 1 and 2

Getting back to that scarf and reversible checks, I finally sorted out the how-to and a repeat in a different number of stitches and rows. Technique 180: disregard console directions. Set up with 1 extra needle and pusher on the back bed at each side. Pusher selection on the back bed as described below matches half the number of stitches in the full repeat starting on the right side of the back bed. End with a single pusher on the far left in the opposite work/rest position of pushers in the group to its immediate right. Reset the front lock row counter manually at the end of each full repeat (24 for mine) back to 000. As an option one may choose to knit half a repeat at the top and bottom of the piece. My first swatch is testing one full repeat + a few rows. My full checkerboard repeat is 24 stitches wide by 24 rows high, composed in turn of a set of 4 blocks 12 stitches wide by 12 rows high. The AX setting changes pusher selection every 2 rows, and the AX 0 rows reverse pusher selection, resulting in the shift in the patterning on the back bed. Knit the first 24 rows (full repeat #) with no lock change, I found it easier to reset the arrow key at the start of the repeat on RC 1 and 2, rather than RC 23-24. The single BW building units are 6 stitches wide by 6 high with blocks 4 producing the 12W X12H repeat segments A working chart for the full repeat: Black dots = pushers in their work/rest positions, numbers on right = full repeat in rows
