A bit of holding 5: intarsia and more 2

So you have some shapes you love and know: wanting to go large, mixing them up, requires thinking things through. Testing on small swatches will help determine holding sequences and whether the results are predictable or even liked. I no longer have access to Adobe Photoshop or Illustrator, so some of my image editing is now achieved in Gimp. Labeling below is with Skitch, and charting is with Excel.

A starting freehand swatch experiment and some observations: shape variations in red areas occur by altering sequence for knitting first and last 2 shapes in the holding position

Planning possible sequences out in charting can be confusing. The image direction will be reversed on the knit side. Approaching the technique like intarsia with individual yarns or bobbins eliminates the need for some of the concerns where 2-row sequences or specific starting sides are necessary to keep yarns continuous or for the execution of the desired shape. Trying to imagine the shapes that create the larger one together in a simple 2D drawing can get one started, but then shapes need to be rearranged. I usually began by “playing”, trying to figure out steps needed, and follow that by trying to produce an executable chart. Making the process as easy as possible to track is always a consideration.

In the chart below the design is worked with 2 needles brought out to work or pushed back into work at any one time, making tracking changing numbers in hold unnecessary. Pink rows indicate starting and ending knit rows, orange “stitches” are cast on and bound off in turn, creating a shape extending out from the edge of the knit. Arrows indicate where shapes meet to create forms.knittable_marked

The red line indicates changing angles. Blue and green lines below indicate increasing rows knit at the center of shapes as a result. extededKnitting and cast on sequences flow around left purl edge, straight or diagonal edges on a chart such as above may become foundation rows that are later seamed. Sort out your sequence and preferences on smaller swatches, keeping notes as you go. Additional shaping can happen along the edges of any plain knit rows between shapes by increasing or decreasing on either or both sides to create crescent shapes or triangle variants.

Now a quandary if gauge matters: knit stitches are not square. One option is to generate a grid appropriate graph paper. In holding sequences happen in 2-row sequences. Graph paper cells may be created at twice the height desired. Each rectangle will represent a single stitch, 2-row sequence. To create your own knitting graph paper in excel please see post as a place to start. A common knit ratio is 4W X 6H. An editable workbook in 2W X 6H ratio that takes into account the following outline in 2 row holding sequences: landscape2X6. Links for designing knit graph papers online:

Using the 4X6 model reduced to 2X3 this is a sample generated using excel, with borders in a 2X6 ratio, so in execution, every single cell represents one stitch and 2 rows knit. The shape is one from the shape menu in the program, easily resized. The yellow bars show the gradations in holding. These cells are too small for adding text within the program itself. The math can be double-checked: there are 70 stitches, 34 rows in the rectangle at the center of the shape. Holding happens over 5 chart units (10 rows actual knitting) at the top and bottom of the center shape; 70/5 = 14 X5, matching the drawing shape on gridThe accompanying, editable workbook Excel 2008  landscape2X6

So the goal is a shawl or garment, graph paper is becoming impractical to follow? Time to pull out your knit leader. Draw out each wedge or piece full size, number segments breaking sections into knitting sequences, and let the KL guide you. For consistency, if the same shape is to be repeated many times and accuracy matters, it may be worth “air knitting” it while noting shaping as you go, keeping a row by row flow chart. An editable workbook to help track holding patterns, increases, decreases, etc. as a starting point for your own preferences: tracking knit.

Gauge or shape does not matter? time to scrumble it all and be surprised!

 

 

A bit of holding 4: intarsia and more

Picture knitting/intarsia may at times be achieved using holding techniques. As in any such knitting, supplies include extras such as bobbins, clothespins, or weighted clips, but no separate carriage. If the ribber is in use and one is working on a large piece, ribber covers allow the yarns to hang in front of the ribber bed.

Some of the rules for accomplishing this using short rows: it is helpful to work from a chart.
Two-row sequences are required, so having the working chart double-length makes the process easier to visualize. “Follow” knitting directions with any tool to determine that the pattern is executable, with no long floats or slits.
The bottom of any diagonal line is always knit first.
Needles are brought out to hold on the carriage side and pushed back into work opposite the carriage; one exception to this rule is if “automatic wrapping” is used. In the latter one, fewer needles are brought into hold than needed opposite the carriage, the row is knit, then with the carriage on the alternate side, the first needle in hold next to stitches just knit is brought out to hold, resulting in a “wrap” and correcting the count to the desired number. Any number of needles may be pushed back into work at any time. More than single stitches brought to hold on the carriage side will produce floats.
When knitting shapes, the only needles in work are those being worked to create that shape.
Base rows of knitting, whether in waste yarn or as part of the pattern, are needed before working in the holding position.
Remember that you are working on the purl side, so any image will be flipped horizontally on the knit side. Reverse the chart horizontally before working on it if direction matters.
Begin with a simple shape. Letters indicate the knitting sequence for short-rowed sections. Patterning in these charts begins with COR. Bold lines separate areas of plain knitting, and letters indicate the order for executing short row segments. The fabric produced lies flat, with no noticeable 3D protrusions.

I find it helpful to use familiar yarn and to work variations of a familiar shape before taking on more complex patterns. Below is a cousin of the first shape illustrated in this post, with a pattern worked beginning COL, repeated across the row, increments in the number of stitches worked in short rows but mirrored on both shape sides (shown in the first swatch segment).screenshot_01filling in to produce a flat fabric, with straight sides: the bottom segment  screenshot_02the top segment  screenshot_04the amended chart
Some of the same shapes may be placed on a shaped edge. The repeat will likely need some editing; arrows indicate the direction of knitting for that row. If the background color is used for casting on and binding off, then the isolated shape floats on the ground, and the horizontal line of contrast color is eliminated.

The yarn used is acrylic, so pressing helps to make the shapes lie flat. Once again, using wool or any other yarn with “memory” will result in considerable curl at the side and at the top and bottom of the knit piece, so that is a consideration in putting in the effort. The more striping, the more yarn ends to weave in and row counts to watch. Using space-dyed or sock yarns may produce pleasing though unplanned stripe patterns in any of the shapes. My samples are not resolved final fabrics. There are many inspiring patterns available for purchase or at times free on the internet for hand knitting, usually in garter stitch as well as holding, resulting in a nearly square gauge, flat-lying knit.
Taking it to garments: accessories are easiest, since the gauge may not be significant.
Shawl shapes in HK are often knit on circular needles, without the constraint of the fixed number of needles on any particular model KM. Sometimes, with adjustments, the same shapes may be rotated sideways on the KM.
Segment sizes may differ due to the resulting change in gauge.
Sampling techniques and shapes in smaller versions help work out the kinks.

A bit of holding 3: shape variations and more

Hand-knit spiraling shawls and shawlettes often involve shaping on every row. Increasing essentially requires casting on one or more stitches. Below are cast-on illustrations from varied sources I used in handouts in my intro to knitting classesscreenshot_19 (1)

screenshot_20

A simple decrease occurs when the last stitch on either side is transferred, moving away from the carriage, the empty needle is placed out of work, and the row is knit.

edge increaseThis illustration shows a fully fashioned version, which gives an edge that makes seaming easier and more attractive, and eliminates the small bumps usually seen along decreased edges. The process adds to the knitting time involved in finishing the piece. Decreases may be made on every row.ff_decrease2

Simple increases: a factor that is often first noticed when approaching seaming is that the carriage side creates loops, while opposite the carriage one gets what looks like a knot, both alternate as the starting position of the carriage swaps sides. To speed things up for single increases, one alternative is to bring an empty needle into work on the carriage side. This creates an elongated loop rather than a full stitch. Unless intended as a design feature, the edge is not the best one for seaming. A better-looking increase is created by putting a needle into work opposite the carriage. For a “good edge,” a minimum of two rows of knitting needs to occur prior to the next increase. Continuing on the thread begun in the last 2 posts, I experimented with every row increase and came up with what I consider a reasonable compromise. The method for increasing on the right edge:
*COR: bring an empty needle into work on the carriage side, knit a row. Insert the transfer tool into the loop created as shown, turn toward the carriage (in this case, clockwise), essentially creating an e-wrap, and hang on the adjacent empty needle hook.

increase every row

COL knit to right*, repeat *  *
In the previous 2 posts’ samples, I did not wrap any needles. Wrapping in both directions can create an interesting line along the center of the “leaf” or “other” shapes, seen in the photo below

experiment smallInterpreting hand-knit patterns for use on the machine requires translations of some of the vocabulary, and directions are given. If an edge stitch is made in garter or slip stitch variations, disregard and simply add it to the total number of stitches on the segment of the needle bed that is being worked on. Wrap and turn is executed by wrapping the yarn around the adjacent needle in hold before knitting back to the opposite side

2: knit <-                  1: wrap COR            1: wrap COL                2: knit -> both

pw2: picking up wraps and knitting them together happens when needles with a wrapped loop and stitch behind it are brought back into work.
The terminology may vary in self-published patterns; some are accompanied by very good tutorials. Ravelry HK searches can inspire many holding technique variations. Other terms to look for in image and pattern searches include swing knitting and, on occasion, tapestry knitting.

 

Charting shapes for automating short row knitting and programming

In machine knitting, stitches are usually brought out to hold opposite the carriage. If multiple stitches are brought out to hold on the carriage side, floats are created. Triangles stacked vertically as seen in the previous post will create a spiral curve along the line where stitches are held. The carriage needs to get to the opposite side and back after each ‘decrease’ or ‘increase’, so pairs of rows are used to execute and reverse angles in short row shaping. When multiple rows are knit independently from the rest of the knit, slits are created. In two-row sequences, these are generally similar to holes created in lace, in longer sequences much larger slits are produced. The latter are often used as planned design elements. The small holes being visible may not pose a problem for the knitter. If they do, wrapping the adjacent needles can help eliminate them, but the doubled yarn in the wrapped needle may create small, sometimes visible bumps on the knit side of the finished piece, creating a secondary pattern.

Reducing eyelet size: in traditional wrapping  required needle(s) are brought out to hold, and the yarn is wrapped under and around the last needle in the hold position on the carriage side before knitting the next carriage pass

                        COR                                                              COL                                both

The “automatic method” for wrapping

Decreasing: if COR (COL), 1 stitch to the hold position at a time, set the machine for holding. Bring one needle on the same side as the carriage into the hold position. Pass the carriage to the opposite side. COL (COR) repeat if shaping is 2-sided, or if shaping is only on the starting side, knit back to it, and with COR (COL) repeat process. Increasing single stitch: bring 1 needle always opposite the carriage into the work position.

Decreasing:  more than 1 needle or stitch at a time: if COR (COL), place 1 fewer needle than required into hold on the opposite side as the carriage, knit 1 row to left (right), toward the needle in hold. When COL (COR), bring into hold the last, additional needle. COL (COR) repeat the directions if shaping is 2-sided, or if shaping is only on the starting side, knit back to it, and with COR (COL) continue decreases on the single, opposite side.

Increasing:  to remove stitches from holding, COR (COL) place the desired number of needles into the working position on the side opposite the carriage, knit one row, repeat with COL (COR) if shaping is on both sides, or knit back to starting position COR (COL) and continue increases on the single, opposite side.

Charting out shapes knitting or programming stacked equal triangles/spirals: the wedge illustrated in the previous post single spiral wedge“Air knitting” is often used to think out fabric issues before swatching using yarn. Drawing lines to follow the carriage movement direction required to keep the knitting continuous, whether on graph paper or within software programs can help sort out shapes that will work in short rowing. Holding needs to happen in 2-row sequences. Below, black lines and arrows indicate the direction of knitting for each row, in this instance beginning with COR. Blue = knit stitches, yellow = all knit rows at the completion of each wedge (2 or multiple of 2, depending on planned design). This repeat is suitable for knitting a continuous strip with ruffling/spiraling at various degrees, not for ‘pie’ shapes.

offset

Working out the repeat: the red line represents the starting, selection (KC), knit row, the numbers at the bottom the width of the repeat, the numbers to the side its height. The first repeat A results in the fewest punched holes, drawn squares, or programmed pixels, requiring being knit double length. The remaining repeats (B, C) are drawn double length, standard card rotation is used. Eyelets form at the held edge. C takes automatic wrapping to decrease eyelet size at the held edge into account. When any sequences are programmed for knitting using slip stitch, the end needle selection is always canceled by using KCII or turning non-needle selection cams in punchcard models.

Going 3D: in many designs, the original repeat may simply be mirrored to be executed. If this is done here, one can see there is no longer a continuous knitting line, directional arrows are moving in opposite directions or toward each other from the center point

Not just for electronics: some punch card repeats to try (also suitable for any machine). End needle selection is canceled.  Selection rows are always toward the first pair of rows knit in a holding pattern, so for the first 2 cards, they would be from right to left. Single rows are punched but 2-row sequences are needed, so cards must be elongated X 2; miter shaping repeat is shown on the left, spiral on the right. Narrower shapes may be created and knit on the appropriate segment of the 24-stitch repeat needle positions. Use needle tape markings as guides for placement. The preselection row is from right to left, the pattern repeat begins with COL. All punched, extra series of pairs of rows of knitting may be added at the top. Note: just a few rows may not be added with a small segment of an additional card with clips, the whole repeat may have to be split into sections to allow for the extra rows and their smooth passage through the card reader. As an alternative, more rows of all holes could be added to the original card when first punched, tested, and then trimmed if not needed. It is useful to try out the repeat as a hand technique first in any of these instances, to determine personal preference.

miter_spiral1

Going 3D: punch only actual holes (black pencil marks were originally used to mark squares that needed to be unpunched for the auto wrap on right, not the best choice for B/W scans). Two-row sequences are punched, so no elongation is needed for either repeat. Miter shaping is shown on the left, spiral on right; mem <– indicates the direction for KC row; decreasing angles are auto-wrapped, increasing angles need not be as seen in the top of miter on left, where needles are returned back to work to create the reverse shape.3Dmiter_spiral corrected

Some ruffle possibilities: all knit rows were added to the card on left with snaps, and are composed of all punched holes. The number of all knit rows between held segments determines the spacing between wedges and the degree of spiraling of the final fabric. KC row needs to be R to L for A, left to right B. Holding sequences are now staggered, changing the angle of the resulting curves. A short float is created where 2 stitches are brought to hold on the carriage side.

The recommended minimum for punchcard length is generally stipulated to be 36 rows. Card A without the added rows is 28 rows high (the last 2 rows are for card overlap when adding snaps), so the repeat below, with the extra segment removed, would need to be punched twice

Vertical racking 3: automating half fisherman in pattern (2)

Working with the half fisherman racking discussed in the last post, here is an approach to interpreting the fabric seen below for knitting on a Brother model knitting machine.  500_557For the sample chart, I chose a 12 stitch repeat, making it executable on any knitting machine. The ribber is set to half-pitch. An often-overlooked clue as to what is happening or is about to be found in the arrows just below the racking position indicator. With the latter at 5, the red triangle appears pointing to L. As the bed is racked to position 4, the red arrow now points to the letter R. This is a simple racking pattern involving only the 2 positions, either to R or L

pitch_rack

Once on position 4, the red arrow indicates the direction in which the bed was racked on the last move (R), the “empty” arrow the direction for the next move (L), bringing the position back to 5. More complex patterns require a bit more planning and tracking to avoid errors.

rack2

Racking patterns in books often recommend beginning the fabric with the setting on 5, or the center position for the machine in question.  Doing so allows for balanced edges in patterns that swing by multiple positions in both directions. In this instance, for the sake of avoiding mistakes in as many ways as possible, I would start the pattern on racking position 10. Racking cannot go any further to the right, so no chance for example of racking to 6 rather than 4 in the knitting because of inattention. Having a “cheat sheet” with row numbers where no racking occurs, and the position of the carriage to R or L at their start and or after the knitting is also helpful. I had to lower the tension on both beds considerably to avoid forming loops that in turn got hung up on gate pegs. Especially at the start make certain that the comb and weights drop properly. Using KCI will ensure that the first and last stitch on the main bed always knit. In the patterning used on the Passap back bed (previous post), the groups of needles in each half of the repeat will change to the alternate position with each pass of the lock. On the rows where the back lock is changed to N, selection continues in pattern, but no tucking occurs. In this chart, the pattern is maintained continuously throughout, while blank “remaining” squares are filled in on rows where no tucking or racking occurs = N, every needle knits. In Brother machines, both tuck buttons are pushed in. Selected needles knit, non selected tuck across the row. new program 2symbols

I tested the pattern approach on my 910, with a 38 row, 20 stitch repeat in a random acrylic. I had some issue with some needles not selecting properly, for whatever reason. The repeat was not planned so a full 10 stitches were at each side of the knit, resulting in the difference on the right side of the swatch photo from its left.

back to scales and knitting them

Overall,  wider repeats and thicker yarns gave me harder to knit fabric, with less noticeable pockets and lack of stretch and “bounce”;  ultimately I went back to a 6X6, 12 stitch 2-row sequences illustrated in the chart above. The thinner yarn needs to be with a bit of stretch, and enough strength not to break when ribbed and racked at the tightest possible tension. This is a fabric that requires concentration, having as many clues as possible to help stay on track is useful. If errors are made close enough to the all knit row, it is possible to unravel carefully to that point and continue on. Mylars or punchcards may be marked to reflect racking position. Here the mark on the right = 10, the one on the left = 9. Marks take into consideration that the card reader’ design row and knitter’s eye level row views are not the same.

A row cheat sheet can help track carriage location for all knit rows. Pictured below is part of mine. Wording for clues or description of sequences should make sense to the person knitting, not necessarily follow a specific formula.

Tuck and garter stitch: from hand knit to machine knit hand tech pattern

A Ravelry question on the possibility of executing a particular fabric on the machine has led to the experiments in this post.
The pattern that led to the discussion is a free hand-knit one,  shared and published on the Purl SOHO website and on Ravelry.
The gauge for their project is 4.75 stitches = 4 inches in stitch pattern; it includes garter rows. Such rows may be executed on home knitting machines by transferring from the ribber (Passap front bed) to the main bed, alternating with reversing the process at a predetermined frequency, depending on stitch type.
K1b is the hand-knit equivalent of tuck for that stitch on that row, adding to the mix.  Not practical for G carriage use, as the latter does not form tuck loops, and hand retooling would be required for all k1b stitches.
Using holding to create tuck stitches in non-auto patterning days was commonly used, and I chose to do so here.
As machine knitters, we are conditioned to believe that single color rows are impractical to execute and that the yarn would need to be cut on each side after the row.
Color changers are on one side or the other, making striping with frequent color changes practical if executed in even multiples of rows.
Transfer carriages are available that will help move stitches from one bed to another. I personally have never had the patience to work with them enough to get good at using them without dropping stitches, so I went back to even lower tech than usual, using the garter bar on the bulky, and beginning pattern row 1 with COR.
Before attempting nearly every row turn, it is helpful to have some practice with turning work over using a garter bar, develop a sequence of repetitive actions, keep careful notes as to what works for you, and use clearly visible contrasting color yarns in tests to better understand stitch structure.
In my sample, the white yarn was thicker than the blue; reversing colors or balancing yarn thickness would change the visual look of the fabric.
Beginning with small samples helps work out issues and the making of the decision to try on a larger project or simply as a border.

Thread lace double bed, and punchcard knit carriage use on Brother 910_2

A short while ago, there was a Ravelry thread discussing reversible, double-bed knits. I recalled a demo from eons ago that I saw at a machine-knitting seminar and decided to explore my memories and share them. The result approaches a “reversible” fabric, with imperfect results depending on the yarns used and other factors. There is a group of knitters that are presently experimenting with “glitch knits”, where the intent is to purposely create patterns with what some people might consider “mistakes” as purposeful parts of the design. For one example, see a video of the technique. The “imperfections” in the fabric below may be seen as a positive by some. It is not the result of any aberrations in the programmed pattern, but rather a result of the way the threads get pulled through each other as the carriage moves across each row knit.

My samples were knit using equal-weight yarns. The fabric may be better served by using different weights, approaching the usual recommendation for plaiting. See the manufacturer’s directions for plaiting feeder use.

Cancel the end needle selection on your knit carriage.
Cast on for full needle rib with both yarns in place.
Hang the comb.
Knit 2 circular rows followed by one more all-knit row.
Change to a rib tension that has been tested for the yarn combination.
Several rows may be knit for a “solid” color edging.

When the first pattern row is selected, one need not set the KC carriage to slip. N is king in Brother, regardless of pattern/ needle selection, as long as no cam buttons or levers are pushed in/ selected, everything knits, whether single or double bed.
After the first row of the pattern is preselected on the main bed, use a tool to push both buttons in as seen below, and proceed with the pattern. Even though end needle selection has been canceled, if the end needles on the main bed are selected, they need to be pushed back to the B position, or those stitches will be dropped.
Plenty of weight is required.

When testing motifs, it is always good to begin to do so using a simple pattern, making needle pre-selection easy to view and check. I began with “checkers”. They can be viewed at the bottom of the image below with the machine set for double length, at the top as drawn on the mylar; most such fabrics are well served by double-length on any machine, electronic machines could easily vary the repeat size or color reverse at the flip of a button, using lili buttons on ribber may add to the mix of results as well.

Thread lace and punchcard knit carriage use on Brother 910_1

Yes, the 910 has no thread lace setting. I happen to also own a punchcard machine model # 892E (no idea why Brother chose to add the E to a punchcard model name). I remembered eons ago reading about someone on an Australian list actually getting a punchcard model carriage to work on an electronic machine. It is good to beware that not all carriages may be interchanged between different models, especially if the latter were manufactured several years apart.

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.

I used two cotton yarns, with a slight difference in weight. With the exception of when knitting transfer lace, the first instinct may be to use the color reverse option when the mylar repeats show lots of “white squares”. However, in this type of fabric blank squares knit both yarns; black squares or punched holes knit only the thinner yarn, while the heavier one floats behind it. The KC tension used needs to accommodate both yarns easily knitting together. When only the thin yarn knits on selected needles, the stitches formed will actually be larger in size than those where both yarns knit together, giving the “illusion” of holes.

This fabric was also at times referred to as punch lace. It is only possible in Brother machines that have 2 cam buttons in the center position, both center buttons under the MC/L mark are depressed. The punched holes/ black squares in mylar select needles that will knit in the fine yarn only. If you are using a very fine yarn for the second yarn, you may have to wrap it twice around the dial on the mast tension unit to control its feeding. Better edges are produced by canceling end needle selection or manually pushing any selected end needles back to B. If KCII is an option on later electronic models, some of the work is done for you. End needle selection may also happen as part of the design repeat, so in those instances, unless you are happy with the thin yarn only knitting on the very edge of the fabric, those needles need pushing back to B by hand as well.

end needle camsset camsBTW: end needle selection must also be canceled whenever patterning with needles out of work is used, or needles on both sides of out of work ones will produce knit stitches regardless of programmed pattern.

If a contrasting color is used as the thin yarn in the B feeder, the results may be seen below. Note: the colors appear reversed to their position in feeders, so A (thick) color is seen more on the purl side, the B (thin) is more evident on the knit side of the fabric. The top of the swatch shows the result when blank rows are programmed into the reader. Sometimes this setting is used as an alternative to replacing the standard A/B feeder with the machine’s plating feeder (if available for your model km). Reversing yarn position can produce some interesting stripes

I have always found the extra B gate on left more a nuisance than a necessity, particularly if the B yarn needs frequent changing.

Another unconventional use for this setting to produce “pretend cables”

thread_lace

It is possible to knit thread lace with the plaiting feeder in place on the single bed as well. The effect approaches glitched versions of the pattern, Stitchworld #407. This is a quick hack to keep the front yarn from slipping out of the yarn feeder The blue and white yarns are equal in weight, the orange replaced it and  is thinner

Picot cast on for every needle rib

Depending on the sort of rib, the beds need to be aligned in most instances so that the needles on opposing beds line up between each other. For this ribber cast on the beds start at full pitch, as you would for EON knitting. Every other needle is brought in to work. A first “zigzag” row is created at the tightest tension possible. On the second row, the alternative needles need to be worked. On Passap E6000 BX, LX with pushers under new needles only will help do the job. On Japanese machines: bring the new needles out to hold, set both carriages to slip. This will result in only those “new” needles knitting on the next pass. The outcome will be one zigzag crossing over the other (red over blue in the photo). Prior to the third knit row, reset the carriages or locks for circular settings (CX/CX, opposite part buttons). Because all stitches will be knitting on each bed, loosen the tension to about three-quarters of the rib stitch size, knit two rows, change racking handle/lever and needle positions to half pitch at their completion. Adjust tension to desired rib stitch size, knit a closing “zigzag” all knit row at tension used for the remaining knit, and proceed in rib
The method may be used both for every needle and for every other needle rib.

Racked ribber cast on and rib configuration tips

This cast-on (on any ribber) is capable of giving a softer, looser start and is good for fabrics that stretch. It is described in most machine knitting manuals.
When experimenting, check the alignment of needles physically before proceeding for knitting ribs on all needles. In Brother machines, the racking grip handle is used in creating “racking patterns”. By turning the grip handle the ribber bed is moved to the right or to the left. The racking position is indicated on the racking indicator. Usually casting on is begun with the indicator in the center position, #5. As indicator numbers rise the ribber moves to the left, and as they decrease the ribber moves to the right. The two cursors can be moved and set to use as an index of the racking range. I prefer to track racking positions in other ways ie. with punchcard markings when possible. The arrows L and R indicate the racking movement and will change position after each handle turn reversing direction is completed. The pitch is set to accommodate rib configurations. In the P position needles on each bed “plain and purl” are directly opposite each other and in a collision course. If EON (every other needle) on each bed is in use, then this position is used to center needles on opposite beds between each other. In position H the ribber needles are centered between two main bed needles.
If observing a suggested needle rule, set up needles using it.
Rack one full number to put the needles out of the rule, and knit one row at about 2 numbers tighter than the final setting.
Hang the comb and wights, and rack again to the original position. Add any edge stitches that may be needed for the specific knit fabric. Knit one row across stitches using the final tension setting.
For every needle rib cast on in my sample I began with the racking indicator on 6, COR, knit zigzag row to Left. Note: at the start of the process, on the left side,  the first needle is in work on the top bed.  The ribber is then racked to position 7. The first needle on the left is now in work on the ribber.  A row is knit from left to the right. The ribber is then racked back to its original position (6). The first needle on the left will once again be on the top bed, and the first needle on the ribber to its right Continue in the planned rib.
Often manuals give suggestions as to the “needle rule” for each type of rib. The sequence below is knit on a Passap. It, in theory, would produce a 2X1 “industrial rib that could transition to every needle or main bed knitting without any holes at the transition point. Note here there is a needle in work between each pair of needles on the opposing bed.

The other recommendation made by many after any ribber cast-on is for 3 circular rows. There is no need for the third circular row. It will actually create a visible line across one side of the rib, that is noticeable, and may not be wanted if it is on the “public” side of the finished garment.
To fill in potential holes produced when empty needles are brought back into work, bring all empty needles into work, and tuck one row across both beds, making certain loops are formed on each needle IMG_2391knit 2 rows circular slowly, some needles hold 3 loops of yarn, switch to ENR rib

tension adjustments may make a big difference, my samples have been knit at the same tension throughout, and single-ply throughout

Some experimenting is required to achieve cast-on rows in the rib that is not too loose or too tight. In this instance there has to be enough slack in the loops so that there is room for racking one full turn, too much will leave loops. Loops created by cast-ons with deliberately large stitch sizes may, in turn, be chained off with a latch tool. The stretch factor and weight of the resulting rib also need to be in balance with the remaining knit fabric. If “improvising” it is always advisable to keep good notes. Most publications and how-tos are really guidelines, starting points for investigating what may be the best method to use in any one piece.

A variation: a racking cast on at a large stitch size can be chained with a latch tool after the work is off the machine to make an edge that nearly matches a chained-off bind-off. It is useful, especially in rib tuck fabrics.
Set up needles in the needle rule and rack out of the needle rule.
Knit one row at a large stitch size, moving slowly to the opposite side. Testing will determine the tension the specific machine will tolerate with the yarn being used.
Check that all needles have picked up loops.
Hang the comb and weights and rack back to the needle rule.
When off the machine, use the method described in the post Ribber cast ons: breaking the “rules”
