Ribber trims 3: one trim, four variations

I found this on a random sheet tucked away with references from some seminar or other eons ago, its origin is not known to me
I like to chart out my repeats and plans for executing fabrics, along with ideas for possibly varying them in ways other than suggested, this was my  beginningThe sequence in photos, beginning with the cast on, 2/24 acrylic yarn,  zigzag  row with inserted ribber comb,  halfpitch 1 row is knit across all stitches to complete cast onknit one more row to return to the opposite sidethe setting is changed to full pitch, stitches are transferred between beds to match  diagramsthe center needle in each group of 3 is brought out to hold for one row, knit one row to return to the other side center needles are pushed back to D position in order to be knit on return pass to the opposite side this tool makes that needle selection faster and easier when the 20 rows had been knit in pattern drop stitches on each side of center stitch transfer ribber stitches up to main bed I knit 3 rows rather than 2, to return to right side  for bind off here is the swatch, still on comb for “setting stitches”

I found the above results upon completion disappointingly wimpy, then tried the same steps in tightly twisted and slightly thicker cotton, achieved better results, but was still not happy. That set me thinking about an alternative way to produce a similar fabric with changes in needle arrangements. The full series of swatches is seen below. The yellow is knit in a 2/8 wool, the beige in the same weight cotton as the white on the right. All swatches were knit on the same tension, for the same number of rows.

The adjustments on the original pattern are as follows. At half pitch begin as above with zig zag to left, 2 circular rows, knit back to right. Set pitch to P, transfer between beds

knit back to the opposite side, transfer each of the side stitches on the top bed onto the center needle in each group,

bring those needles out to hold for easier knitting on the next pass knit one row back to the right,  making sure stitches  have  knit off  properly. When you have returned to the right side, set the carriage to tuck from right to left only (left tuck button), RC000loops will be formed on the center needles as they would have been formed over the needles as if holding was in use

when the 20 rows are completed the carriages will once again be on the right,  all stitches will have been knit on the previous rowtransfer all ribber stitches to top bed, knit 2 rows, bind off. None of my swatches were blocked other than by some tugging, particularly along the bottom edge. The spacing between stitches is narrower because ladders created by single needles left out of work are formed by yarn lengths that are shorter than those that happen when stitches are knit and then in turn dropped. The height of the swatch is also affected, and the half fisherman texture in the wool swatch, in particular, is more evident.

More variations to try in a multiple of 3+1: using either method or a DIY cast on, dropping (yellow) stitches marked with a * at the end, or transferring them to right or left and setting the main bed to tuck in one direction only.When the work is removed from the machine, stretch cast on outwards, then give each “scallop” a really good pull downwards. Steam lightly over the scallops to set them. Variations of the double bed trims may be worked on the single bed as well.

Ribber trims/edgings 1

An example of a common ruffle/ frill is produced with variations using both beds: cast on for every needle rib, knit X rows at full fisherman rib, followed by X rows at half fisherman, and then possibly by plain rib for X rows, EON rib or even following with transfer to single bed for X rows, bind off. The yarn used in this swatch is a wool-rayonExaggerated frilled starts: no cast on needed, working on every other needle patterning on both beds.  A few rows will produce a curly edge, more rows a ruffle proportionate in depth to the number of rows.  

Passap KM: AX/AX or AX/KX 4-10 rows, continue in plain rib N/N
AX/KX 4-10 rows, knit 1 row N/N, transfer to 1X1rib, continue to knit in plain rib
racking cast on
BX/KX 6-10 rows, continue in plain rib
Pushers in upper work position (UWP) will make the needle knit while those in the lower nonworking position (NWP) will respond to lock patterning settings. E6000 either program front bed for the pattern (1000), or bring every other pusher completely out of work to avoid having them return to work position after the first pass. The motif repeat for 8 stitches/rows usable on any machine

Working it on Brother becomes a bit fiddly. Whether working on a punchcard or electronic KM, it is possible to introduce patterning on either or both beds as seen below.  I preferred the look obtained with the racked cast on at the start. Setting up the Brother machine: program the repeat, half pitch for every needle rib, air knit to place the pattern on the bed so that the first needle on the left (or right if you prefer) is preselected forward and will produce a knit stitch on the first row knit.  The yarn used is a 2/24 acrylic Both beds are set to knit, lili buttons will be in use. On the ribber bed, the second needle from each side will knit, so starting on the left side on the ribber the first needle to the right of the first needle in work on the main bed is brought into work. It will need to be the second needle in work when the carriage moves from left to right in pattern knittingnow another needle on the ribber is brought in to work on the far left, it will tuck with lili selection when moving from left to right remember the ribber rule with lili buttons: an even number of needles must be in work, this shows the start and end of selection on the ribber on alternate needle tape markings, as required It is sufficient to continue with no circular rows after the first zigzag one. The start will be “loopy”, but will improve when the bottom row is stretched vigorously. In this Brother version, the first row of the pattern needs to be selected toward the carriage and yarn after the first pass by the paired carriages. Beginning COR, a row is knit to the left side. The knit carriage is removed from the bed and brought back to the right. COR: a “free pass” can be made with the machine set to tuck in both directions as well as to slip. Using tuck avoids errors in recalling to switch cam button functions.  Using KCI (or II) the carriage with no yarn makes the free pass preselection row to the left, where the carriages are coupled again. I used KCI for my swatch. Before continuing to knit make certain lili buttons are engaged, that both carriages are set to tuck in both directions, and continue in pattern for X rows. Switch both carriages to N/N and continue in every needle rib (or knit 1 row N/N, transfer and continue in EON rib or single bed). If stitches are transferred for EON rib or stocking stitch knit on a single bed, the yarn tension will need to be adjusted.
To review: lili buttons on ribber, checking needle selections on both beds. Cast on with no circular rows, zigzag only, option 1: tuck <– –>, tuck <– –> loops will build upon every other needle for single rows, so the frill can be continued for any desired height
option 2: tuck <– –>, tuck <– –> to desired # of rows, knit 1 row N/N, transfer for 1X1 rib
option 3: combination slip/tuck
With no circular rows after zigzag note the edge, and the amount of stretch

Using a racking cast on followed by same carriage settings as above
COR zigzag row right to left
COL rack 1 to left (increase 1 number on racking lever), KCI (pattern pre-select), program row 1 of pattern, knit one row to the right
COR rack to right (decreasing number) set both beds to tuck, knit X rows (I chose 10).  After completing the desired number of rows continue in every needle rib or knit one row with carriages set to N/N, transfer for every other needle rib, and continue on EON rib.Both pieces compared for width and rippling

I was plagued with random dropped stitches after my transfer to EON rib, one seen above left.
I finally sorted out that I had been using a ribber arm from an older model punchcard machine. When I replaced it with the later model arm shown at the top in the photo below, etched by the factory with #2 (outlined in magenta), I no longer had any problem.

The latch opening plate use and installation

Here the latch opening plate has been secured into place in the connecting arm without the #2 mark. The change in height is noticeable, brings the unit closer to needles when on the machine during knitting

A reminder: if the needle presser bar on the ribber (all plastic) is to be removed, it is reinserted back in with ridges facing, and flat side down

More on Brother DBJ, including KR 260 bulky KM options

Any repeat suitable for a 2 color 24 stitch DBJ separation published or self-drawn for a 4.5mm machine is suitable for DBJ on the bulky. At times yarns ie 2/8 to 3/8 wools that knit stocking stitch at tension 8-10 on the main bed and are too thick for every needle rib on the standard may produce a fabric that is not too dense, and still has some drape at lower settings for tension on both beds on the bulky. Electronic standard knitters can double the size of the repeat prior to separating the 2 colors and then work on every other needle both beds, proceeding as usual for DBJ. Thicker yarns begin to make too thick a fabric for wearables, may work well for other uses. If some drape is required, the ladder back method becomes the preferred one in bulky KM DBJ. I no longer have available the bulky dbj samples from my teaching days, my 260 KM is not set up, so, for now, this post will not include swatch photos. As always swatching is a necessity to determine whether the resulting knit is one that meets our expectation, preferences, and often, patience.

To review: the 260 KH carriage will be familiar to Brother punchcard 4.5 mm machine users and has the option for creating thread lace (“split” cam button in center position), which is not commonly available in Brother models.

The Brother 270 electronic knit carriage offerssimilarsettings

There is no automatic method for eliminating end needle selection ie KCII, rather, adjustments for it are made on the underside of the carriage, as in other punchcard machines terms of DBJ, the electronics allow for the familiar KRC 2 color separationKR 260 parts as described in the ribber manual, followed by possible settings for cam levers are illustrated below. The absence of lili buttons is immediately noticeable. There is no automatic every other needle selection on the bulky ribber carriage shown, as opposed to that choice being available on the standard KM.

hand selection tools for either bed, 4.5mm on top,  sometimes interchangeableevery needle selector for standard, operates similar to Jac 40, EON here for use bulky, adjustable 17.5 inch workshop cut model in a plastic for 2X2 selection on bulky nowadays 3D printed custom options are also beginning to be available

The DBJ setting that requires the least intervention on either standard or bulky machines is the one produced with the separated motif being knit with the ribber set to slip all needles in one direction, and to knit every needle in the other. Reproducing the lili effect is done on the KR 260 is achieved with hand needle selection. For birds eye, where every needle is in use on an even number of needles in work on the ribber, select every other needle on the ribber beginning with the second needle on the right for preselection row, push up to holding position. The ribber carriage is set to slip both ways, will knit hand selected needles as it makes its way to the opposite side. Now select every other needle on the ribber beginning with the first needle on right, bringing those needles up to hold. Stitches on those needles will knit on the ribber as the carriage makes its way back to the left and to the color changer. Colors continue to be changed every 2 rows as in any standard 2 color birdseye fabric. 

Ladderback or modified Jacquard is at times used on standard machines specifically for the effect created on the fabric reverse side, and most often used with bulkier yarns in order to be able to make a garment with more drape than it may have in regular jacquard, or to knit large designs with no long floats. This technique on the KR 260 ribber involves hand manipulation of the ribber stitches to reduce the number of stitches created on the ribber as well. Ribbing is often set up in order to produce a band that is not hugely different in stretch and width than the body of a garment, with further transfers for the ladder back configuration when it is completed. No more than one needle is usually in work on the main bed beyond needles in work on the ribber bed. If an additional needle on the main bed is required, it should be on the left-hand side. The rib is knit as tightly as possible, tension is loosened as one progresses into the jacquard portion of the piece. Common arrangements are 1X1, 1X3, 2X2, etc.  When needles are arranged in “even groups” ie 2X2, 2X4, 4X2, etc, the lili setting or manual needle selection to emulate it on the 260 may be used. Tuck settings may be experimented with as well, but tend to create a more noticeable vertical line between ribbed repeats on the knit face. The larger the number of needles in work on the main bed between ribber needles in work, the more the main bed tension needs to approach that used for the yarn when it is knit single bed. 

In EON ladder back an increase on the ribber is usually necessary after 4 increases on the main bed. On the bulky, this may be needed as often as in every 2 rows. The hand needle selection must remain constant throughout the piece to maintain the birdseye backing or any of its variants, which are based on pairs of needles alternating functions every 2 rows. Striper backing is achieved by selection of the same needle for each of the 2 colors used, slipping the opposite color needle locations. First needle selection on right is easier to track by marking the location of the first needle used on that side on the needle tape or needle bed as a guide for subsequent rows. 

The row counter will show double the number of rows than if the fabric were produced in Fair Isle. Four passes of the carriages complete one design row. The motif will appear elongated to a degree depending on the yarn and techniques used. Ladder back and vertical stripe backings may produce vertical separation lines in the fabric that may be quite noticeable depending on color, tension, and yarn used. Watch closely for dropped stitches or split ones. Splices and knots in yarn may tend to break due to use of added weights and tension. Plan on adding new yarn at sides and use ends to seam up, or use Russian join before the point at which a new yarn end is required, and continue knitting. The latter has become my favorite even in lace knitting on the standard machine. A recent tutorial on the technique may be found here <https://www.mybluprint.com/article/this-method-of-joining-yarn-ends-is-pure-magic>

Check alignment and oiling requirement of machine frequently. 

Other backings: one color backing. The main bed is set as normal for DBJ, but the ribber is set to knit for 2 rows of one color, and to slip for 2 rows with the other color. This means on any machine (unless using 2 electronic carriages as described in another post) the operator has to change ribber settings every 2 rows. It will now take 4 carriage passes to complete 2 rows of knitting. Floats will be formed in the non-backing color, may be caught on the ribber on slip rows, so check frequently, begin with small repeats, always test new yarns or even a different color or dye lot in same yarn on swatches prior to committing to larger pieces. 

Patterned backing: selection of ribber needles in blocks of alternate colors, or selecting ribber needles in between those selected on the main bed applies here as well. Yarn thickness and end product serve as guides as to whether the fabric serves one’s purpose or preference.

In large areas of solid color on garment face, if bleed through is noticeable, a pattern of 2 black rows alternating 2 white ones may need to be programmed, with color changes continuing as in pattern areas. If the goal is simply to match density or drape, then continue in settings used for design area without color changing. Most punchcard double jacquard separations and “rules” apply to both standard and bulky machines.

Later posts: ribber bind offs at first, and casting on. I was never quite content with ribbed edgings on my bulky knits. There are always several options for achieving a look that pleases us more, or a technique that will alter the unwanted results. In this instance, one is to knit a row on the main bed after several rows of waste yarn, continue with the body of the garment piece, rehang that first knit row, knit the rib upside down, and bind off. The latter can happen on the machine, by hand off on waste yarn with a “sewing” needle, or removing the work onto hand knitting needles and going that route. The 260 ribber manual recommends the following method. 

Having the waste yarn U style with an opening on right with the bind off beginning on that side, or finding a way to mark the first needle on the ribber in the sequence may make finding that needle position easier when the knit is off the machine.

This illustration, also from a Brother manual, slightly edited, shows the sequence for how the yarn is threaded through the stitches in numbered sequence according to stitch configuration for the ribbed fabric

Geometric shapes on ribber fabrics with tuck stitches 2; knitting with 4 carriages

When switching between N/N and tuck/ tuck on the ribber it is not necessary to switch the tucking lever from its up position to the lower one. The ribber will knit every row when used in either of these settingsIt is possible to knit this type of fabric using color separations such as those seen for one type of DBJ where color one for each design row knits 2 rows, followed by color 2 for corresponding design row also knitting for 2 rows. Each color may be drawn and programmed once, followed in turn with elongation X2 on both punchcard and electronic machines. I prefer to work with the elongated images, believing it makes it easier for me to correct errors or knitting problems, should they occur. This color separation is the default on Passap. In Brother electronics it would need to be hand done and programmed. It is best to start with simple shapes. This triangle series has been used in several of my previous posts. The chart shows the transitions in the process

Brother DBJ settings using tuck on either bed, not addressing hand needle selection on the ribber for production of reversible fabrics. The yellow color highlights cam settings that require changing by hand for every other pair of knit rows, and making the changes with each color change. With the exception of the bottom 2 the same settings were used in some of my brioche variation experiments. The resulting fabric, knit in reverse order from chart (top setting down to first). The dropped stitches happened when I did not notice the ribber weight was resting on the floor, with no resulting weight on the fabric. There are single repeats of each motif. Two more possible DBJ variations

A full range of DBJ variations of the same repeat, including ones using slip stitch and shared in a previous post, executed in both one and 2 colorsPassap knitters have the option of arrow keys and stitch type on the back bed that make fabrics possible with ease that are daunting to reproduce on Brother machines. There is a category search on my blog that will lead to a collection of posts on the topic of knitting with 2 carriages selecting patterns.

I have often considered the possibility of using 2 coupled knit and rib carriages for some of my patterns but found it limited knit width because of carriage stops on the ribber bed, the unwillingness to have my ribber carriages fly off the bed, and the added limitation imposed when both carriages are selecting needles. Now that setting changes were required every 2 rows on the ribber I found a solution of sorts. It is one of those try at your own risk tips, but for me it made several of the last swatches in brioche achievable far more quickly and accurately.

As in any knitting with pairs of carriages, when needle selection is happening from opposing sides, the turn marks need to be cleared on each side of the machine as the opposing carriage begins to move across the needle bed to avoid breaking the belt.

I happen to be knitting present swatches on my orphaned 930, which still knits producing interesting sounds. It came with no carriages. I am actually using a knit carriage from a 910 and one from my 892E punchcard machine, with a magnet glued to the proper location facing the rear rail. I removed the stopper pins from either side of the ribber bed, placed lace lace extension rails on both sides as well as the color changer with all change buttons released as seen in this illustration. On the left, as the carriages move beyond the end of the needle bed, the return signal lever is tripped, making a characteristic noise. A that point the turn mark on the left has been cleared, and it is safe to operate the carriages from the right toward the left
The right side of the machine is more problematic. The extension rail will store the knit carriage safely, but the ribber carriage has to move out enough so without its stop it would fall to the floor. My solution was to jerri rig an extension the appropriate height so the ribber carriage could slide out as much as needed while being supported. I was able to knit the hundreds of rows required for many swatches with no problem other than operator errors. Here the pair of carriages on the right are seen resting far enough off the machine to clear the belt, at an adequate height for them to slide off and on easily. At first I secured the connecting arm to the connecting pin with an elastic “just in case”, but that proved unnecessary. 

I have been asked lately about the lili setting used in all my ribber carriage illustrations (center position). I tend to use that as a default to prevent errors and for consistent quality in my ribbed fabrics, especially if matching gauge ie in garment pieces or bands is needed. That said, for the carriage to travel far enough on the right in this set up, the slide lever had to be used on I. The plastic tray helped reach the appropriate height, and made for easy slide off and on. There are a few minutes of maneuvering when setting up first selection row. As always it is good to begin with familiar yarn and previous experience with double bed fabrics.

Some of my own operator errors are due to the fact that I still am not used to the fact that the 930 appears to revert to factory defaults with each new design entered, that I have to remember to switch from isolation to all over, that the image is reversed on the knit side like on punchcard machines unless the reverse key is used. I spent decades using the 910, where once the selections were made and once the pattern variation buttons were set, that became the default until buttons were changed for specific applications.

The 2 pairs of carriages may also be used for vertical striper backing using lili buttons on Brother machines, and for both slip and tuck variations of same. I will add information in a separate post. More “patterns” are possible as well, emulating some of the Passap possibilities for its back bed settings.

Lace transfers meet fisherman rib, 2 color ribbed brioche on Brother machines 2

Over the years I have avoided ribber fabrics that involve hand manipulation of stitches in addition to patterning. Runaway stitches are hard to see and repair.

In these fabrics transfers are made by hand with multiple transfer tools. As stitches are moved, the last of the stitches transferred on the purl side (in this illustration 4 stitches), one will lie directly behind one of the stitches on the main bed (marked in red), sharing the same needle hook space. As the next row is knit, the needle emptied by the transfers picks up a loop. The following knit carriage pass will complete the stitch on the needle holding the loop, and the eyelet.

My recent posts reminded me of a repeat from an older Brother punchcard pattern book that combined lace transfers and fisherman rib. The original repeat is shown on the left, designed for use on punchcard machines.Stitch and tuck loop combination transfers are made every 4 rows, prior to knitting that row in the opposite direction. The machine is set for half fisherman rib. Tucking happens on top bed on all needles in one direction only, the ribber remains set to knit both ways throughout.If all transfers originate on the same spot, a vertical line of eyelets is producedCan plaiting give me 2 colors the “easy” way?
If transfers move to the right or the left, an arc will be createdAiming for the punchcard pattern book inspiration I began at first by marking up the needle tape with water soluble pen to help track repeat segmentsAfter a short trial swatch I sought to automate needle selection to serve as a guide for moving stitches across the needle bedThe main bed is set to tuck in both directions. White cells tuck, black cells knit. Rows in Brother preselect for the next row with each pass of the carriage, so on even number design rows as the carriage moves to the opposite side, all needles will form tuck loops on the main bed. The next row will be preselected, with some needles now back in B rather than D position. With an appropriate transfer tool, move the stitches on the non selected needles to the adjacent selected needle to their right after pushing it back to B position. After each transfer push all worked needles and their stitches as well as he now empty needle to E position. As the carriage returns to the opposite side an all knit row will be completed. Several tension adjustments may be needed to insure loops do not get hung up on gate pegs as stitches move across the bed, while still being loose enough to knit off properly.

The charts below reveal planning for a 2 color repeat with mirroring of the original above. Seeking new geometry, the repeat “inspiration” is mirrored horizontally. The final repeat is on far right. The knit carriage is set to tuck in both directions throughout. On white cell design rows the main bed tucks, the ribber is set to knit. On mostly or all black cell rows the main bed will be knitting, the ribber is set to tuck. In this fabric the transfers are made on knit stitches created on the previous row prior to moving the carriage back to the opposite side. All transferred stitches and the empty needle are brought out to E position prior to moving the carriage to the opposite side, will be creating the second all knit main bed row. Transfers are made every 8 rows, with pairs of transfers being made toward each other, no longer all in the same direction as in the single color sampleThe central repeat is color reversed to achieve the final repeat on the above right in order to produce those transfers on knit rows. Final row count needs to be a multiple of 4 rows in height. Here is a 2 widths 36 stitch X 32 row repeat chart The extra line seen occurs when one forgets to reset the ribber to tuck, and stitches are all knit on a “wrong row”. It is by coincidence that they seem to occur in the same spot in the repeat

more accurate knitting

On the bottom half of the swatch below the difference is the result from when one carriage knits every row on both beds, requiring a change on the knit carriage as well, canceling its tuck setting with every other color changeThe last repeat may be flipped vertically as well. It then needs to be edited so those white squares land on the row after an all knit row, not below it. The final repeat on the right is 36 stitches wide by 64 high. There are still 8 rows between transfers. On the left is the first resulting chart, on the right the amended chart so selection for transfers occurs on the proper row.the germ of one last idea, the repeat 14 stitches wide by 96 high, max transfer seven stitches (odd #)playing with ideas a bit more, max transfer six stitches (even#)

This was my attempt to shoot for a recurring shape and planning on having transfers land on a like color, the repeat is 8 stitches in width, 112 rows height. Six stitches are the max number transferred. More would give a wider curve, the final repeat would be exponentially longerits reverse side :
When the main bed tucks in both directions with one color, knits in both directions with the other:I did try to eliminate those lace holes. On the right of the swatch as shown below I threaded a needle and attempted to close the eyelets with stitches, getting closer to the line one might get in a hand knit. On the left I hooked up loops to fill the empty needles. The latter changes the intersecting lines completely.

Geometric shapes on ribber fabrics with tuck stitches 1

The previous post elicited a facebook query as to whether it might be possible to create solid shapes within the field of brioche vertical stripes. The inspiration for the query was a hand knit pattern published in ravelry 

https://www.ravelry.com/patterns/library/pariss-brioche-scarf

Many terms are used in instruction manuals and published directions. In my notes I will refer to fabric with tucking on both beds as full fisherman rib, tucking on one bed only as half fisherman. These were my first attempts at exploring the inspiration idea, the fabric has inherent differences as it requires both slip and tuck stitch settings, so technically it is neither fisherman. Knitting happened on a random drop stitch day, which explains the patterning interruption errors.When attempting to knit isolated geometric areas on a field of frequently tucking stitches, automating the task when possible makes the process easier and faster. This was my first “diamond” pattern repeat, suitable for a punchcard machine as well. The design is illustrated on the left, converted to punched holes/black squares/pixels on the rightThe knit carriage is set to tuck throughout. The programmed repeat will alternate the knit/ tuck functions across the bed based on black squares, punched holes, or pixels.For full fisherman rib (top swatch) the ribber needs to tuck in one direction only, opposite to the action taking place on the main bed. A choice needs to be made on either of these 2 setting directions based on needle selection on the main bed and stays fixed throughout knitting. The ribber is set to knit on even numbered design rows on the card, to tuck on odd. Row count numbers may be different than design row ones depending on row counter settings by the operator or built KM ones. Below are tuck settings for to the right on top, to the left on the bottom.

For half fisherman rib (middle swatch), the ribber is set to knit with every pass.

Note the half fisherman fabric is narrower than the full. Also, I am not used to my 930, overlooked that the machine was set for isolation, so its bottom diamond shaped repeats are incomplete.

In the bottom swatch, I tried to produce a more distinct shape on tubular tuck created with only knit stitches on both sides of the fabric. Hand selection on the alternate beds on all tuck rows produced knit stitches in the desired area. A needle out of work made it easy for me to find a proper location on the needle bed.

Getting back to automating at least part of the process for such shapes: the repeat needs to be altered main bed will be knitting the black squares in the chart on the right on every row, tucking the white ones. When the ribber carriage is on the side appropriate for it to tuck the following row and no needles are selected in design segments on the top bed (odd numbered design rows, ones with majority of black squares, tuck may not be used in those locations because then the resulting stitches would be tucking on both beds with nothing holding the tuck loops down.

bring all needles between selected main bed needles up to hold on the ribber so that they will knit while the remaining needles tuck on the next pass of the carriages.

In my sampling, the ribber was set to tuck when moving from right to left. Below is the resulting swatch, shown on both sides. Part of one diamond shape is missing due to the fact I was concentrating on moving needles around and missed the change in selection on one side of the machine.Back to the original the method used in the previous post where ribber settings are changed from knit to tuck <– –> every 2 rows along with color changes. I chose a design that would make it easy to identify the location of non selected needles on the main bed on rows where ribber will be set to tuck in both directions. The result is interesting, but the solid areas, narrower than the remaining knit, are in the opposite color to the dominant one on each side, the reverse of the inspiration fabric.
When needles are not selected on the main bed, interrupting the every needle selection bring all needles on the ribber between selected needles up to hold on each of the 2 passes from left to right, and right to left. Stitches on those needles will knit rather than tuckresulting in this fabric The first swatch at the top of this post was achieved going a very different route. Two knit carriages were used to select and knit from opposite sides of the machine. Each carried one of the two colors. When working with the first color and coupled carriages the main bed is set to tuck <– –>, the ribber to knit <– –>. The second color is knit using the main bed knit carriage only, set to slip <– –>. A knit sinker plate may be altered and used so as to knit on main bed only rows, adjustments to it are shown in post http://alessandrina.com/2018/04/15/ribber-fabrics-produced-with-2-knit-carriages-selecting-needles/. The chart for my working repeat with a multiple of 4 rows in each pattern segment, color changes every 2 rows indicated on right trying to produce a diamond shape using this technique, my first repeat had arbitrarily placed pixels:the cam settings on the right of the swatch images correspond to those used in each swatch segment. Colors were changed every 2 rows throughout. First 2 rows in the pattern were knit in tuck setting, followed by 2 rows knit in slip. In segment B when no needles were selected on the top bed, all those needles were brought out to hold before knitting to the opposite side. Because every row is now knitting in the corresponding color changes the result is a striped pattern. Segment C is knit with both carriages set for 2 rows as in C1 alternating with knit carriage only set as in C2. At that point the color being carried knits only on the ribber, skipping non selected needles on the top bed, avoiding the striped result. A float is created between the beds in areas where no needles are selected that will be “hidden” as one returns to knitting in rib with 2 carriages. The arrow in the chart points to an area where two colors were picked up with the color swap rather than one. The resulting swatch samples

Analyzing the result in section C: the diamond is the same color on both sides, whereas the initial rectangular shape experiment reverses the colors. Reworking the diamond repeat in segments that are each a multiple of 4 rows:Other considerations in DIY designs. The background-repeat for this pattern is actually composed of units 2 wide by 4 rows high. If the pattern is intended to be repeated across a larger number of stitches on the machine bed than that in the chart, it is always worth tiling the image to pick up any errors (sometimes happy design features). Tiling in width readily shows an errortiling in height as well proofs row intersections as welltiling the corrected width repeat, now 42 stitches wide by 72 rows high sometimes tend not to keep immediate notes when I test ideas, which often comes with a price. I knit my first swatch using this repeat beginning the pattern with 2 rows of tuck, resulting in this fabric (and some randomly dropped stitches once more) with the same color diamond on both sides:Beginning the pattern with 2 rows of slip stitch on the main bed only mirrors the swatch at the start of this post. Where no needles are selected on the main bed, with passes of the combined carriages, two rows of tuck will now be produced, resulting in the wider geometric shapes and the increased bleed throughThe tuck loops created by the white in this instance have the elongated slip stitches in the alternate color (blue) partially covering them, creating the darker geometric shape in the top detail photo. The blue is thinner than the white, the effect will vary depending on yarn weight and tension used for the main bed yarn. One can begin to observe the change in width in areas with more stitches tucking. 

If the aim is to have a tighter, more clearly defined diamond, after the swatches rested, the swatch that began in slip stitch setting appeared to “work” better to my eye, even with the single color geometric shape on both sides taken into account. Ultimately the choice is a personal one. The wider vertical stripes created in the white yarn in the slip combination fabric happen because of the 2 stitch wide repeat on the top bed as opposed to a single needle one in a true fisherman knit. Because of the slip setting the results will be narrower in width from it as well.

Ayab knitters will need to program any repeat across the width of the intended number of stitches, and use the single setting. Electronic knitters can enlarge the background pattern field easily, or create brickwork, extended repeats.

Arah-paint offers a free program that allows drawing repeats in different orientations with a few mouse clicks. Shifting this pattern must also be in pairs of pixels/black squares in this instance because of the 2X4 stitch background unit. The 21 (half) pixel shift shows an error in its continuity 22 stitch shift results in a “correct” all over repeat

Quite some time ago I experimented with shadow knits including in posts

2013: DIY design2017 crochet

It occurred to me the same design might work in a tuck rib version. The original repeat was 24 stitches wide, 28 rows highscaled to double length, 24 stitches wide by 56 rows higha tile test of new pattern Knit tests: the red yarn was a very strong cotton, hard to knit smoothly, the blue encountered some stitches not being picked up on the main bed as well, but the concept may be worth exploring further. The main bed is set to tuck in both directions, the ribber to knit throughout. The red and white fabric is considerably wider because of the tension required to get the red cotton to knit. Better stitch formation results with the different yarn used for the second color

And lastly, a first quick adaptation of a design previously used for drop stitch lace, which requires some further clean up the yellow squares indicate loops tucking on both beds at the same time, the repeat on the far right is the one tested after eliminating those problem areas. It is 14 stitches wide by 80 rows highan “improved” version, the choice remaining as to whether to make all the blue shapes pointed at top and bottom or “flat” this is my repeat, tiled. It is 14 stitches by 84 rows

2 color ribbed brioche stitch on Brother knitting machine 1

After a complicated nearly 3 months I am returning to some knitting, and am sharing some of my results once again.

I have always found 2 or more color patterned brioche stitches executed in hand knitting as inspiring and complex challenges to admire, but am not tempted to actually attempt to execute them in any way.

I have not knit on a Studio KM in more than a decade. I have been asked whether this fabric is possible to produce on Studio/Knitmaster. The most crucial difference imo between the 2 brands (Passap has its own universe) is the fact that Studio selects and knits with each pass. Needle pre selection for clues is not an option. I have gathered some information from manuals on tuck knitting including “English rib and Double English rib” as clues to anyone who wants to work out the technique sorting out their own Studio settings tuck on studio km

This was my first Brother machine knit swatch result:

Each of the 2 colors tucks for 2 rows and in turn knits for 2 rows alternately. Settings are changed manually as shown below after every 2 rows knit, following each color change on the left. Making things a little easier: the top bed may be programmed on any machine, including punchcard models to avoid cam button changes in the knit carriage every 2 rows. With the main bed set to tuck <– —> throughout, black squares will knit for 2 rows, white squares will tuck. First preselection row is toward the color changer. When no needles are selected on the top bed (white squares), ribber is set to knit. Top bed will tuck every needle.

When needles are selected on the top bed (black squares), the ribber is set to tuck in both directions. The ribber will tuck on every needle.

Proof of concept: blue yarn is used on rows where main bed needles are selected (black squares). The crossed stitches at the top right begin to represent an effort to create surface shapes or designs on the fabric. They are created by cabling 1X1, making certain the stitch creating the “shape” is carried to the front side of the fabric, the opposite stitch crossed so it is facing the knitter.I used KCI in this instance, first needle on left in work on ribber bed, last needle on right in work on top bed. A border is created on the knit’s edges on the far right and left. The reverse side of the fabric:

Using a blank square on a knit row to help track 1X1 transfer patternsWorking the 24 stitch repeat using KCI; both first and last needles in work on the ribber bed. Due to operator error and forgetting to change ribber settings after transfer row, I chose to stop knitting rather than attempt a pattern correction

Another attempt at cabling, 1X1 and 2X2. That white line in the bottom image on the right was caused by the color changer picking up and knitting both colors for part of the row before my noticing it. I got rid of the “wrong” color from the feeder and continued on. The wider 2X2 cables require “special handling” and eyelets are formed on columns aside them after transfers are made. Before attempting to knit crossed stitches such as the above in an every needle rib, it is worth exploring cables crossed in vertical stripe color patterns single bed. This is a hand knit inspiration series of patterns, better left to hand knitting

one of my ancient machine knit demo swatches:

On any knitting machine with every other punched hole, black squares or pixels locked on a single row, id the pattern is knit in FI, continuous columns of  vertical color are created. 

If the the goal in creating the continuous an unbroken vertical stripe 2 color pattern, one must place like color on like color. Because FI is essentially a slip stitch the fabric will be tighter, narrower and shorter than that produced knitting either yarn in stocking stitch. Cables on the machine need to be transferred across fixed widths between needles, so there are distinct limits as to how far stitches will allow their movement in groups in either direction. Loosening the tension can often help. Sometimes it is possible to create extra slack by a variety of means, making moving the stitches easier. I have found my own limit for this fabric was working with a 2X2 cross (it is possible to work moving single needles as well). Adding to the complexity single bed: proper needle selection for the next row knit needs to be restored prior to knitting it when using the FI setting, movement of stitches is mirrored on the knit side in the opposite direction of that viewed on the purl. Visualizing some possibilities as worked on the purl sideto consider the knit side appearance mirroring is not enough the direction and appearance of the crossed stitches on the knit surface is reversed from that on the purl as well 

When working every needle rib it will take 4 rows of knitting with 2 color changes to produce the striping. R represents stitches on the ribber, K the stitches on the knit bed

Tuck stitches widen the fabric. As a result, the tucked knitting in this chart on the ribber (represented by the color yellow), forces the space between the knit stitches produced on the main bed (represented by the color green) apart, while stitches tucked on the ribber will create the gap between the stitches knit on the ribber, appearing on the reverse side of the fabric. The combinations create the appearance of single stitch vertical stripes.

This is an illustration of one possibility for programming reminders for tracking location of cable crossings 

Every needle ribs are generally knit at tighter tensions than when the same yarn is knit single bed. Too loose a tension in any tuck fabric causes problems with loops forming or knitting off properly, too tight will produce stitches that do not knit off properly. One limitation of crossing stitches here is the actual stitch size, which needs to be constrained to produce the fabric. Tiny stitches need to travel across fixed space. One by one crossing is manageable, 2 by 2 requires extra slack to make the transfers possible.

Adding some “give” to crossed stitches
1: the carriage has moved from left to right after the color change. All needles except for the four white squares in my design were preselected prior to the next row of knit. The carriage now stays on the right
2: take note of the white tuck loops formed on the ribber on the previous pass from left to right
3: white tuck loops ( I chose center 3) are lifted up and off their respective needles and allowed to drop between the beds. This will allow the 4 white cable crossing stitches to have more slack. 
4: cross your cable in the intended direction
5: push cable stitch needles out to E
Knit from right to left, change color, continue in pattern 

With some planning on longer pattern repeats it is possible to plan added clues to tracking rows on which the cables occur, and their location on the needle bed. Repeats with very few marked areas merit testing in tile as any other repeat. The repeat on the left when tiled shows the area of a patterning error, on the right with the missing blank rows added the problem is shown to be resolved.A proof of concept swatch:Planning for all over brick layout of corrected repeat: More detailed charts of the 2 repeats, suitable for punchcard machines, editable further for use in electronics. Ayab knitters need to repeat the final motif across the width of the download to match the number of pixels to the number of stitches in use across the needle bed, use single setting.

 

Fisherman/ English tuck stitch rib 1/ checks patterns/ Brother, Passap

WORK IN PROGRESS

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 with no patterning or rackingfor fisherman rib recommended Brother ribber “needle rule” 

Adjustments to needle rule may be needed depending on fabric. If only one bed is knitting while the other is tucking, having first and last needle in work on knitting bed. In English (aka half fisherman rib) only one (either) bed tucks.  Directions marked with green #6 on left are from the Brother Ribber techniques. The remaining images are for single color racked checkerboard pattern from Brother Punchcard Pattern book #5. No pattern card is involved, the every other needle arrangement suggested on the right accommodates slightly thicker yarns. 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 work. On a punchcard 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 for 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 check patterns

here again for a 16 row sequence

On fabrics with racking enlarge stitch size by1/2 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 knit for two rows, and tuck 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 proper position on every row. 
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 same functions in same locations on 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 racking pitch number beginning with design row number 1, 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 distortedChanging color every 2 rows shows the same leans in 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 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 row) 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 on 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, the last on the back bed. This is also variable depending on fabric being knitted. Using the repeat

tech 129: (black square tuck for single row) on front bed. Set up back bed after prep rows, making sure pushers are 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 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 with bottom 3 blocks using 6X6  on back lock, N in front. The back bed pusher set up is doing the patterning. The top 3 blocks are set to pattern selection on both beds, using AX, arrow keys, and KX on 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 tuck needles on 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  . The needles on ribber immediately below the ones tucked on the main bed are brought to 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 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 set up is different than when one is planning textures in varied patternsIt 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 lock set to AX and key for an even multiple rows divisible by 4. I used 24-32 to get a sense of scale. The arrow key was cancelled for the next 2 rows AX 0 to switch the pushers.  The working repeat became *32 rows 6X6 ,  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 rowsAfter 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 left. After 12 rows, the arrow key was cancelled for the next 2 rows to AX 0 to switch the pushers. The working repeat became *12 rows AX,  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 the 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 operator and 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 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, 260. Some techniques adding back lock settings: 106, 114,145, 158, 167, 168, 190. Techniques 259, 260, 269, 270 use racking; 200, 212 require manual changing of arrow keys; 284 uses the U100 transfer carriage in combination with fisherman rib for an embossed effect.
Using FX setting 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 back bed in pattern after first row of pattern, make certain they are in the opposite arrangement of work/rest positions on front bed. EX knits  on all needles from left to right. Black squares represent knit stitches, 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 how to and a repeat in a different number of stitches and rows. Technique 180: disregard console directions. Set up with1 extra needle and pusher on back bed at each side. Pusher selection on back bed as described below matching half the number of stitches in the full repeat  starting on the right side of the back bed. End with single pusher on far left in the opposite work/rest position of pushers in 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 top and bottom of the piece 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 of 4 blocks 12 stitches wide by 12 rows high. The AX setting changes pusher selection every 2 rows, the AX 0 rows reverse pusher selection, resulting in the shift in patterning on the back bed. Knit the first 24 rows (full repeat #) with no lock change, I found it easier to reset arrow key at the start of the repeat on RC 1 and 2, rather than RC 23-24. The single BW building units are units are 6 stitches wide by 6 high with blocks 4 producing the 12W X12H repeat segmentsA working chart for the full repeat: Black dots = pushers in their work/rest positions, numbers on right = full repeat in rows

Parts and accessories “hacks” / adaptations

WORK IN PROGRESS

There were back rail and carriage/ parts modifications from year to year. Any of these carriage swaps may not work across model years, and should be tested with caution. I happened to have magnetic ” rectangular pin backs” from some of my previous projects, was able to remove the magnets fairly easily and to obtain consistent results using them

Using punchcard knit carriage on an electronic knitting machine
The magnet on the back of the electronic carriage is what trips the reader in the 910. With the 892 and 910 carriages side by side, I marked the approximate spot I wished the magnet to be. It is presently in place with cellophane tape for my tests. I believe it to be a rare earth magnet, 12 mm in diameter, part of a jewelry piece from days gone by, with a deep attraction to all KM metal parts.

the first location was too high, pattern did not read properlyplace40what turned out to be a much better spot 

Punchcard lace carriage on electronic, adapted from video; it took a bit of fiddling with getting the magnet positioned properly. A resulting test swatch knit on my 930 using a built in pattern on the right

Ribber fabrics produced with 2 knit carriages selecting needles

Altering the KC sinker plates and arm: remove 6 small screws from the sinker plates, leaving only their arm

The carriage with the altered sinker plate in place in turn will then be used to replace rows that were to be knit with the ribber set to slip in both directions <– –> . In my sample it operated from the right, with the combined carriages (KC2), from left. 

I have random parts, some never used. When trying to familiarize myself with a 930 I came across the ID for one such part I had never used. It turns out it was intended for older ribber connecting arms on newer model beds

There now is a 3d printed device for the Passaphttps://vimeo.com/101599762. It as well as the earlier mercer plating device http://www.knittingparadise.com/t-396061-1.html require gluing or drilling to affix parts to locks, are not easily available. At one point in time I tested a far “simpler” version of a yarn feeder for a second, thinner yarn aiming for a plated effect, using a thin plastic tubing taped securely on a passap yarn feeder. The goal is to keep the tubing clear of any needles as the locks move across the knitting beds.Samples were knit on Brother machine (left) and on Passap (right): on Brother needles were set up 2 in work, 2 out of work. On the ribber an even number of needles were in work, with lili buttons in use, and the ribber carriage was set to tuck in both directions while the main bed remained set to knit throughout. Passap had the 2 in work 2 out of on work needle arrangement on the front bed set to N, with pushers one up, one down, both arrow keys in AX (tuck setting) on the back bed, fabric is not “blocked” in any way. 

Reversible DBJ, Brother knitting machines

I am including notes on my working through the process and some of my stumbles at the start of this post. More specific how tos are found toward the bottom of it.

Such fabrics may be created with both the KRC built in function, or with the color separations that knit each color for each design row for 2 consecutive, identical rows. Punchcard knitters are not excluded. The starting side is on the left for the KRC setting (B in this illustration), on the right side for the alternate color separation (C, double length or drawn with each row repeating X 2). I am still testing my 930, for my samples I began by using the built in pattern #16 in the Stitchworld Pattern Book I.In the absence of a jac40 the fabrics are knit by manually selecting stitches to upper working position (E on Brother) on the ribber bed every row. Preselection for the next row to be knit on the main bed makes the process far easier.

In my first sample, the colors are the same on each face. Since the same number of needles are selected for both design and ground, both sides of the fabric will be exactly alike. There will be floats, enclosed by knit stitches of the opposite color. Beds are set at half pitch. Consistency makes any process easier and more predictable. My ribber set up was also with an extra needle on the ribber at either end of those in work on the main bed. I found I had less issue with the long floats in my design when I made certain the needle selection began with needles to the left of those in work on the opposite bed rather than to the right, allowing for the color in use to knit first on the ribber, then in turn on the main bed. It may not matter with patterns with shorter spans worked between the 2 colors. The dropped stitch issues below were resolved by using different yarns, no other changes. 
The needle set up in colored squares and on my needle beds showing matching selections on both beds (different design rows). Some of the floats may be seen created by the blue yarn in the bottom photo. If first and last needle on each side were not selected on the main bed, the needles at each end on the ribber were added to hand selections for next row (blue squares)


better results with the different yarn choice

For DBJ that reverses ground and pattern colors, opposite needles are selected on each bed. Color 1 knits the design on one bed and the background on the other at the same time, while color 2 knits the reverse. There are no floats. I knit this fabric as well at half pitch. The ground color created pockets (white squares), with the pattern color (black squares) locking the layers of fabric together. Here again, first and last needles on the ribber were worked on each row. I began pushing needles up on the ribber beginning to the right of each needle in work on the main bed. Needle selection on ribber matches unselected needles on main bed (pink). All needle positions each bed are mirrored.

needles actually selected on both beds (pink), different design rowOne design row, 2 different angles

Since ribber fabrics are not visible for a large number of rows, I frequently scrap off after short distances to proof technique before committing to longer pieces as well as to asses whether the effort is worth it in order to produce the fabric in that particular technique or yarn.

Moving on to a self drawn pattern, the technique proved to be sound. On inspection however, I saw I was actually missing a pixel in the .bmp I downloaded, and on the reverse the green arrow is most likely operator error in needle selection. The orange dots highlight the missing pixel/contrast color stitch, and on the color changer side I had a really sloppy edge that needs sorting out (red dots). A possible added factor: I knit the motif using KCI, and later recalled end needle selection does not always work with the carriage I am using.Here I filled in the missing pixel, and drew a single pixel black line along each side, testing a “border”. The first and last needles on each side were now cast on and in work on the main bed.

That single stitch solid color line does not add to the design in my opinion, so back to the drawing board: side “border” pixels are eliminated. The first and last stitch are now in work on the ribber. This fabric is the best by far, at the very start I forgot to cancel end needle selection (KCI), then switched to canceling it, KCII on electronic.The how to in summary: first and last needle are on the ribber. On the electronic choose KRC for the built in color separation for the fabric to be worked in DBJ. KCII (no end needle selection). With free pass to right, both carriages set to slip <– –>, select for first row of knitting to be worked in color represented by white squares in the design chart. Both carriages remain set to slip in both directions throughout. On the ribber bed, bring up to E/hold position first needle on the right of any needle selected on the top bed, then continue to push needles up into work to match the number of not selected needles on the knit bed. As needles are arranged, there will be a space between the last hand selected needle on the ribber, and the next needle in work on the main bed Now that there is that extra needle in work on the ribber on the color changer side, to match selection as seen above, needles are hand selected to E beginning on the far left, still keeping that space just before the next needle selected by the pattern reader. Remaining selections began to right of needles on main bed as described above.when selection begins on the main bed on the leftGetting back to working the same pattern on both sides of the knit: first needle on the left is on the ribber, the one on the far right on the main bed. On the electronic select KRC for the fabric to be worked in DBJ. KCII. With free pass to right, both carriages set to slip <– –>, select for first row of knitting to be worked in color represented by white squares in the design chart. Both carriages remain set to slip in both directions throughout. On the ribber bed, bring up to E/hold position first needle on the left of any needle selected on the top bed, then continue to push needles up into work to match the number of selected needles on the knit bed. Small selection errors are seen on left image, ie on the second row on its right, may be easily repaired by duplicate stitching. The stitching yarn may be fed easily through layers of double knit for short distances before and after the “mistake”. With all settings and yarn being equal, there is a difference in size between this fabric (larger of the 2) and the one with color reverse on its other side 

A similar set up, working in full pitch. Here needles line up directly below each other. If wrong needle is selected it will be point to point with the needle immediately above it, and is an added clue the wrong needle is being pushed up into hold/ E position. My first swatch had distinctly different side / vertical edges. Cast on was for every needle, half pitch (top image), first needle on left on main bed, last needle on right on ribber. When completed, it was followed by change to full pitch prior to pattern knitting, lining up needles point to point, directly below each other (bottom image). I prefer the edge obtained on the half pitch throughout, seen in previous  sample 

Still pondering those edges, and what about repeats with large areas of solid color? The image on the left is 25X26 rows in height, the one on the right adjusted for an even number of solid color rows, and a total row repeat divisible by 4, 25X28. The single black line at the top is a marker for returning the carriage to all knit when the top of the repeat is reached. When using full pitch, solid areas remained open at both edges with carriage set to KCII. A wooden tool handle is actually inserted through from one side to the other in the bottom of the swatch. Because the needles are point to point, no extra needles could be brought to work on both ends as a work around. KCI will select end needles on main bed. I tried that as the first work around to seal the edges. I paid no attention to whether needles were selected at each end every row, and got another creative pair of edges.

Returning to half pitch I brought up to work the first needle on the left every row (too many rows at seen at R top edge compared to other side) and pushed the last needle on right up to work if it was not part of the group to be brought up to E.Analyzing the fabric structure in those areas of solid colors on alternating beds: at first full pitch makes sense if one has knit tubular stripes or solids which have closed edges, with the yarn making a single pass on each bed, traveling back to the color changer, with the option to stripe every X, even number of rows. Such stripes occur evenly spaced and identical on both fabric sides. Here the goal is to knit the fabric with large blocks of solid, alternate colors on each side. The main bed knits color 1 on selected needles on the top bed only, the alternate color is knit with the ribber needles being hand selected up to E while the main bed is slipping, with none of its needles selected. Other than that first set up row with preselection from the left, 2 rows are knit in color A, followed by 2 rows in color B. There are no stitches traveling between the beds to seal the fabric together in those areas, creating open sides, so if the goal is to have the edges seal. other steps need to be taken. A single pixel solid line along either edge of the repeat did not create a good edge. Full pitch is easier than half pitch to manage. One possible solution to both issues is to alter the side edges of the design repeat so there will be alternating needle selection along those side edges, thus sealing the fabric.

I decided to cast on with white, and to continue with white as the first color used in pattern (white squares in chart). This swatch was knit in full pitch. Edges are sealed throughout. The only hitch was when the top was reached and that all black squares row was reached. I was on the right at that point, with my dark color in the feeder. The row toward the left would have knit in the dark color instead of the white on the top bed. I cut the dark yarn, made a free pass to the left, continued in plain knit in white to right, and then transferred stitches and bound off. Top and bottom edges /borders in terms of number of rows, whether to add pattern there as well, are all subject to personal preferences and taste.
