Ladder back double jacquard: backing variations

Periodically questions come up with regards to how to manage float control other than using familiar DBJ settings, or the best way to proceed to achieve it when one prefers to work in thicker yarns.  In this technique, all main bed needles are in use for patterning and in working position, the ribber needles can be arranged in nearly any configuration in groups with 1 needle in work, and one or more needles out of work. The main bed tension is close to what would normally be used for a single bed fair isle, while the ribber is set at least one or two whole tension numbers tighter, thus reducing bleed through or vertical separation lines on the “outside” of the knit. The fabric uses less yarn than every needle rib DBJ, is lighter in weight, has more stretch, but will not lie as flat. In Brother, if needles are arranged in groups of 2 (pairs of lines and spaces on the needle tape with even spacing between them (i.e. 2 X2, 4X4, 2X4, etc) then lili buttons can be used. The latter method has less chance of the backing showing as a vertical line/ separation on the pattern surface. Sometimes the ribber needle arrangement may result in a secondary, interesting pattern on the purl side. It is still a good idea to have floats that are limited in width, generally less than 5 stitches. For the purposes of illustration, I knit 2-row stripes on the main bed, while altering settings on the ribber.
This was my initial setup. The ribber needle tape is marked in what I think of as dashes and blanks, in continuous pairs. When using single ribber needles for the ladderback, the number of out of work needles may be even or odd between the ones in work

As each row is knit the ribber will pick up yarn, or not, depending on carriage settings, creating a knit stitch vertical chain on the purl side of the knit 
If empty needles are simply brought in to work above plain knit rows, eyelets will be created. One way to reduce their size would be to pick up loops between stitches on the main/ opposite bed and use them to œcast on your ribber needles. With ribber carriage set to knit in both directions, each color will knit with each pass of the carriages (2).
With it set to knit in one direction, slip in the other, each color will knit on the ribber for a single pass, slipped in the opposite direction, and the slipped stitch becomes elongated (3). Having a needle in work on the ribber close to the edge of the knit may help reduce the roll along that edge (4). A slight separation may appear on the knit side in the location of the vertical columns created by the ribber stitches, it is less apparent when ribber knits on every other row  It is possible to only have one of the 2 colors knitting on the purl side. In my case, it was white knits, blue slips. Here the ribber carriage settings need to be changed with each color change, so for white I used

for the blue

Setting up for using lili buttons: needles need to be in pairs, each with a matching “dash and a blank”, even number of out of work needles in between them. My previous set up required a bit of moving stitches around
 ribber is set to slip both ways, lili buttons engaged With the above settings, the needle on the right of each pair will catch the yarn on the pass to the right, the needle on the left of each pair will pick up the yarn on the way back to the color changer. Stitches are elongated because they are slipping alternately for one row, and are slightly offset from each other with a bit of a “jog”  because they are not knitting on the same pass. This is noticeable in lili backed full DBJ as well. The color change from blue to pink is simply because I ran out of blue yarn. My ribber stitches should have been tighter throughout, but even in this tension situation, the knit side has the least noticeable vertical separation along vertical column edges in the series of tests The technique may be used on any machine. This sample was knit on a Passap, using one of the patterns built into the console, pushers 2 up, 2 down for long stitch alternating color vertical lines, fixed distances between them, BX <–/LX, Tech 179.Similar backing may be produced on the Brother machine, but now a hand technique is involved. The ribber remains set to slip <– –> throughout, no lili buttons. The spacing may be chosen on the basis of the interaction with the main bed motif, or in a different configuration for each color, making the hand technique easier to track. Needles are brought to E position on the ribber for each row to be knit in that color. Here the different colors are easily identified

the ribber settings

There are 2 options: one is for bringing appropriate needles to the E position for each color only once. I chose to do so immediately after each color change, with carriages on the left (below dots). The other is to bring them to E for the second pass of the carriages on their way back to the color changer as well (above dots). There is elongation in stitches in both options, less so when each color knits on the ribber for 2 consecutive rows, where one short and one longer stitch for each color may be observed. The first option also caused a bit of puckering on the knit side, which disappeared with pressing.

the reverse side 

Similar ideas, playing with the configuration of color blocks on either or both beds, can result in applique, embossed jacquard including pleats, and a whole range of other double bed knit fabric variations. A quick sample with transfers between beds

Lastly, here is a tiny swatch in an arrangement beginning to explore the odd number of needles in work on the ribber in conjunction with the use of  lili buttons and adding needles to “fool the machine” as described in the post

 

Drop stitch lace using Ayab software

Some notes on how tubular software color separations such as the one automated in the ayab circular setting may be found in the previous post

In an effort to respond to a request I have had via my blog, I am sharing information on this topic as I have time to explore it. My first attempt when up and running with the Ayab software, was to reproduce an earlier sample I had created as a color separation originally intended for a hand-knit shadow knit experiment.

a chart from that blog post  try_drop_stitchthe resulting hand knit, on the purl side
IMG_0823the color-separated sample knit pre ayab the sample knit using the Ayab circular setting

Patterns predawn for shadow knitting, appear to be one published source for interesting 2 color drop stitch variations. What about geometric shapes or developing your own designs? Designs created using this technique lengthen considerably when off the machine. Both color sets of stitches become elongated as they are dropped, and that should be a consideration in planning your design. If your goal is a circle, the actual shape programmed may have to be closer to an egg laid horizontally rather than that of a “true” circle. The fabric also widens considerably when blocked and off the machine, making the cast on and bind off methods considerations another necessity. Design repeats may be drawn in Paintbrush or GIMP (both freeware), or Photoshop. I have been a long time GIMP user, and prefer to use it in tiling repeats as opposed to the copy and paste features in Paintbrush to accommodate the Ayab requirement of programming the repeats horizontally in the width of your piece.

In my previous, how-to posts on designing your own 2 color drop stitch lace, part of the color separation required elongating the design X 2. The starting side in Ayab for needle selection always needs to be from left to right, and elongation of the motif is not required when using the Ayab circular option.

This was my first working repeat, A = repeat charted out. B = the working bitmap or png, etc. (which would be the only requirement for the mylar). C = the image tiled for the chosen number of stitches (again, Ayab requires the repeat to be programmed for the width of your knit piece). D = the image elongated, not usable for this fabric, it results in too much elongation. If you would like a knit border on either side, that can be achieved by having extra stitch(es) in work on the ribber. a possible ayab repeat, 56 stitches wide by 36 rows high

The results up to the point in which I had a yarn caught in brushes and stitches dropping on the left of the needle bed:

Drop stitch lace has been referred to over the years in other terms as well, such as release stitch, drive lace, and summer fair isle in Passapese. Passap knitters will recognize the results from this first method are akin to those produced using Technique 185.

Getting started: stitches intended to be dropped may be created on either bed. If the ribber is used to create loops, then the technique is a manual one. Using the main bed in Japanese machines to program dropped stitches increases accuracy and ease.

If you are swatching and testing, a permanent cast on is not necessary. The broken toe cast on is one of the two quickest on the Japanese machines, usable on either bed. It is fondly called that because if ribber cast on comb and weights are in the wrong place so that the wrong loops are dropped, everything falls to the floor, and likely on your toes. There is an online video by Diana Sullivan that shows its use for a tighter cast on row in 1X1 rib, but the use here is for a different purpose.

In producing this fabric you are technically knitting every needle rib. Cast on a fairly tight zig-zag row. The ribber comb wire needs to be placed so that it holds down the stitches on the bed on which you need to keep them. The principle and results are akin to the first row knit when you use a single bed cast on comb, and the second pass, with the first knit row anchors open loops before you continue to knit. Any loops not secured by the comb will result in dropped stitches. Any fabric, any time, when 2 stitches are empty side by side, stitches are not formed and the yarn is dropped off them creating a float or ladder.  The red line indicates the ribber wire on top of the ribber loops in the zigzag row, placed so released knitting will be left on the ribber. Black lines your zig-zag yarn loops, blue dots the teeth of your ribber cast on comb. You can check placement by dropping just a few loops on the main bed before hanging your weights on the comb. 

zigzag row showing the placement of cast on comb teeth, on each side of main bed needles
with wire in place, anchoring ribber stitches testing out dropping a few stitches all stitches now on the  ribber in preparation for dropping stitches created on main bed 

It is possible to also use a wired cast-on comb for an open stitch cast on the top bed only. Remove the wire from the comb. Bring the comb up and between needles to be used, and re-insert wire. Needles and latches will need to travel easily under the wire when the first knit row takes place. 

The knit carriage will not clear the comb properly because of the location of its brushes, etc. For the “cast on” row, exchange the sinker plate on your knit carriage for the one normally used with the ribber. The first photo below shows the approximate location for the comb during the first row knit. Needles are centered between the teeth, the teeth themselves line up with gate pegs. The comb needs to be manually held in place since there is no opposing bed in use to help balance it. Working with the ribber up would ease the process in wider pieces of knitting. The ribber sinker plate has no brushes or wheels to anchor knitting on the knitting bed. Any rows knit single bed using it, will need to have needles brought out to hold position prior to knitting each row for all stitches to be formed properly

the comb in position pass is made slowly with the ribber sinker plate in place the comb is dropped  bring all needles out to hold position  knit one more row, returning to starting position change sinker plate on knit carriage if needed, proceed with knitting

To use the same method with ribber in place: hold the appropriate ribber comb with the bump(s) up facing you, so that the teeth line up with gate pegs as shown above, and so the needles can come through the gaps. Leave the wire in, hold the bump(s) against the ribber, and tilt the comb against the knit bed. Hold the comb high enough to take the carriages across to the opposite side. Move carriages to the other side, drop the comb and weigh it. If continuing on the top bed only drop the ribber, switch sinker plates, and continue to knit.

“bumps”: Brother comb 

For other purposes and an edge similar to a weaving cast-on executed on Japanese machines use EON for the cast-on row, then bring into work and add the rest of the needles prior to knitting the second row.

Use a cast-on comb appropriate for your knitting machine’s gauge ie 4.5mm, 5mm, etc., the brand is not relevant, only tooth spacing is. It is possible to cut ribber cast on combs into different widths for use when knitting is planned on fewer stitches than those accommodated by their available commercial widths.

As for dropping those loops that will form the long stitches, one can do so manually with improvised tools. For more automatic dropping of stitches using knit carriage in Brother patterning, one may punch a card or draw a mylar with a method akin to color separation. A pass of the KH carriage across the knit is made with no yarn in the feeder, color 2 is actually no yarn/empty from left to right while establishing the proper needle selection on its return. The ribber would need to be reset to slip, or the ribber carriage separated from the knit one for the 2 passes to and from the color changer. This is the “scariest” option by far, more error-prone. It is not applicable when using the circular Ayab setting in creating the fabric. Without a specific tool, all stitches can be brought to E and back to B with a ruler, piece of garter bar, ribber cast on comb, or other handy ‘toy’. Dropping stitches is done while carriages are on the left, after the return to the color changer side. It is possible to modify the Studio accessory used to drop stitches

For 2 color drop stitch, the main bed is set to slip in both directions. Because not all needles on the main bed are used for patterning on every row, the KC II setting on the change knob is used, eliminating end needle selection on the 910. The ribber is set to knit every row

Ayab: begin  your design repeat on your first row, choose its circular setting in machine type pull-down menu on the right
The first design row is preselected left to right
The main bed is set to slip <– –>, change knob on KC II (end needle selection is canceled)
Ribber is set to knit <– –> for the duration
COL: as you go from the left to right, needles are preselected on the top bed, they will knit, picking up loops that you will in turn drop on the subsequent passes of the knit carriage from right to left.
COR, the KC knits on preselected needles as it moves to the left.
Clear the color changer, set up your next color. Drop the stitches knit on that last pass

It may be necessary to push those loops down between the beds before you next pass, remember to pull down on your knitting periodically,  visually check needle alignment on the main bed (all needles in B in the work area)

*With the new color move to the right, preselecting the next row of loops
Knit right to left, picking up loops on preselected needles, change colors, drop stitches,** and repeat * to ** steps in 2-row rotations

so I want circles, here is my test pattern more like eggs, the black squares in shape appear as drawn on the purl side shapes are reversed as drawn on the knit side 

It is possible using the circular setting to drop only one of the 2 colors, whether background or shape. I began by dropping the white ground. I used to encourage students to develop a tune/ repeat in their heads when regular actions needed to be taken. For me, in terms of yarn color,  it was “white, knit, drop”,  “brown =  erase (push back to B), go back”. 1: white travels to the right, needles are pre-selected; 2: white travels to left, picking up loops 3: on left, change color, drop stitches. For brown: 1. travel to the right, needles are preselected 2: on the right, before traveling back to left push all selected needles back to B. Only the ribber knits on the way back to left, so brown will have knit 2 rows with no dropped stitches. I ran out of brown yarn, started over with the blue and white, planning on having the shape drop the stitches. There is a difference in the fabric width with the change in the distribution of stitches. I stopped knitting, not due to any mispatterning, but because I encountered another Ayab behavior that may be well known to punchcard knitters. Due to a yarn mast issue, I moved the knit carriage back to disentangle the yarn, and lo and behold the pattern advanced a row.  Punchcard machines will advance a row with any movement of the carriage outside the edges of the knit. This was never an issue in the unaltered 910. At that point, I stopped knitting. 

Not fond of stripes? prefer one color? the sample below was worked on 40 stitches in width, using the repeat charted for 56 stitches. Here decisions are made at the design phase of your repeat. For single color, drop stitch use an image double length, and single setting in the Ayab software. The process is the same: *preselect stitches left to right, knit on selected needles right to left, drop loops just picked up traveling to left**, repeat from * to **. Settings are the same as for the 2 color drop stitch, but the elongation depending on the number of stitches dropped is not as noticeable. The texture in my swatch is diminished after a quick press, the yarn is an acrylic blend. The charted repeat illustrated is wider, but I worked it on only the center 40 stitches. As always in slip stitch, the black squares knit and they represent the stitches that are dropped. If you wish to create the long stitches on the ground (white squares),  reverse use Ayab Action Invert prior to knitting

the chart as viewed and explained at the top of the post

Sources of inspiration from studio publications vary, patterns designed for pile knitting make for suitable one color drop stitch. A partial punchcard repeat

from an electronic collection

and a punchcard pattern book, where markings emulate eyelets, usable only for single color knitting 

Note that in #2 card directly above, there is a solid row at the very start that is a design row (third all punched). In Ayab again, first-row preselection is left to right, you will be picking up loops on preselected needles going from right to left and then dropping them. That first design row needs to have punched holes or black squares/pixels in it. The color separation is essentially done for you in the source image. Do not use circular in Ayab, but rather, use “single” setting and follow instructions for creating the fabric as described above,  with no color changes. The blank punchcard rows match the no selection rows in self-drawn color separations,

If double bed work is daunting, for a different stitch, worked single bed, that may cause interesting distortions in all knit, single bed fabrics see block stitch post.


The self-drawn design repeats for 2 color drop stitch may be offset as well, resulting in colors being dropped alternately.  The design shape needs to be created in 4-row blocks in order for the yarn to make it back and forth to the color changer with both colors to complete one design row. The second pairs of rows in each 4-row block is erased. In this instance as well, rows marked with black squares will pick up loops on the main bed, which are in turn dropped to create the long stitches. The second design repeat is offset to try to get sections of it to create loops to be dropped as well. The final motif must be a multiple of 8 rows in height if it is to be used as Ayab’s infinite repeat in length.
Color changes are indicated in the vertical strip in the center of the design. This was my starting idea

Elongation to 4 rows per block, erasing the second pair of rows for each color on right. The repeat on the right may be used if only one color is to be dropped; the 2 blank rows in the design field represent stitches that will knit only on the ribber for 2 rows. No stitches are dropped in color(s) used in sequential rows of blank squares in all “white” areas of the chart, including multiple rows above and below the design shape. Color changes every 2 rows continue, creating continuous stripes. shapes staggered, visually checking for placement of alternately dropped stitches 

To accommodate the Ayab preselection for the first row to be knit from left to right, move the last blank row in the design to the first-row position. As the carriages travel from left to right and back to the color changer, the stitches will knit 2 rows only on the ribber. Continue knitting in steps as described earlier in the post, changing colors every 2 rows. On a larger knit ground such shapes may be arranged to suit. This was my working repeat, but I used a third fewer stitches in the swatch than in the chart. Note that the images will be reversed on the knit side, so if preferred, use Action Mirror to flip the image horizontally prior to knitting it

The swatch has been quickly pressed, so the texture is flattened out, but I am reminded of a few shadow knits when viewing its purl side.

In an unaltered 910 with the ability to double the width of the programmed repeat, mylar users are not excluded from exploring a similar fabric. The repeat above may be rescaled to half the width,  drawn that way, and then use the twice as wide built-in feature. Gimp does an “interesting” thing when scaling this design to half-width, note the right side of each repeat is an odd number of squares, the left side an even. The repeat may be used as-is or redrawn, adding or eliminating black squares if symmetry in each shape matters.  Paintbrush produces the same image, mirrored.

The explanation: further analysis of the original design reveals the fact that some of the pixel numbers in the design black square blocks are uneven in width. In this instance, 3.5 is half of 7, and half pixels cannot be rendered, so the software assigns the split to 4 and 3.  

 

Combining knit carriage needle selection with racking

4/23/18:  inspiration source is from a Russian pin, bottom left #198

The first swatch, produced with manual selection, and varying the number of rows between racking to establish yarn tolerance

There are single rows of knitting on both beds, so the option of using 2 knit carriages is out of the running. My test swatch had the main bed doing all the knitting, the ribber knitting the joining segments with manual changes in its buttons from slip to knit and back when appropriate. The staring needle arrangement, on “graph paper”, and the subsequent racking positions: the top illustration is for racking position 4, the bottom for racking position 0.A tentative plan of attack: the combined knit and ribber carriages are to be used throughout. The main bed KC is set to knit, but the change knob is set to KCII. The blank squares will actually knit thanks to the setting, the selected needles will indicate the direction in which racking is due to take place prior to knitting the next row. 

This is the starting ayab repeat, with single repeat segments highlighted (one alone would be adequate for most other electronics). 

You will be working on the purl side of the knit. In what is an increasingly irksome feature to me, Ayab will automatically mirror horizontally any loaded image, so to get the above, you need to actually be either mirroring the image prior to loading it (my preference), or remember to do so through Ayab’s actions after.  Enter this, the ayab screen shows this 

This is what appears on the left side of the Brother ribber. I prefer to rely on other methods to track directions and numbers of positions in racking, but the ribber itself provides some clues. My pitch lever will not move all the way to H, but that is made up for in the ribber adjustments, so it is not a problem. A reminder: turning the racking handle to the left is toward increasing numbers on the indicator, to the right is toward decreasing numbers  The set up for my swatches, and the first row knit on racking position 0.  

The first preselection row in Ayab knits above needles on both beds. With carriage on the right, set the ribber to slip <–  –>, and knit up to the next row where needle pre-selection appears. *Change the ribber button on the side to match the direction in which you will be moving the carriage (left if knitting to left, right if knitting to right) to knit from the slip setting, knit to the opposite side (no more needle selection), change ribber lever back to slip again prior to any more knitting.** Repeat * to **. Position 4:

I began to run into issues with ribber stitches being too tight, this was knit with a tension adjustment, resulting in a less defined texture

Going a different route: another repeat, with each position, repeated once, repeat is pre mirrored  
a swatch with the racking happening only in the center of needles in work

Starting position can be variable. With more stitches cast on, while keeping the same ribber configuration, racking can happen further to the right or to the left. There need to be enough stitches on the main bed so ribber needles do not travel beyond them when racked. The knit bed uses tension close to that used for stocking stitch. The ribber stitch size may need to be adjusted to allow for a wider move toward either side. A looser ribber tension results in a less sculptural surface on the knit side. I have seldom been able to knit more than 6 rows on the main bed with ribber combination stitches on Brother, often maxing out at 4 depending on the yarn. Consistent habits help develop one’s own most meaningful reminders for taking action.

5/12/18 2 more samples. This time racking is done by 3 positions, the ribber setup is with 3 needles out of work, and 5 in work. Set up is with the racking handle on 3, move to and from positions 0 to 3. Knit 4 rows single bed. Rack to the next position. Use ribber set to knit for 2 rows for the sample on left, for a single row for the sample on the right 

A printable “rib setup” to aid in charting  P and H needle configurations, with some space for notes and carriage settings

My step-by-step interpretation, which may be worked as a hand technique on any machine 
1. racking handle on 0, cast on for every needle rib
2. transfer stitches to the main bed to match the needle arrangement above, and knit 3 rounds
3. set the ribber to slip in both directions, knit 3 rounds
4. rack 4 to the left, set the ribber to knit, knit 3 rounds
5. set the ribber to slip in both directions, knit 3 rounds
6. rack 4 to the right, set the ribber to knit, knit 3 rounds*
repeat steps 3-6

The Brother Ribber Techniques book provides guidelines for variations on this stitch type,  the following among them. It is available for free download online from various sites and is an excellent resource

These images were shared on Facebook, they are from the Empisal ribber stitch book

I have worked with racking in the past but never attempted to have racked shapes interacting with single bed patterning across the width of the piece on the KM. My 910 is presently connected to a Mac via the EMS Ayab kit. Sampling is quick and easy, replacing the mylar. One critical difference is that the repeat used must match the pattern in width numbering the same as the needles in use for the piece, so at least for testing my initial repeats were 30 stitches wide.

I find trying to chart things out before I actually knit helps me plan and understand what actions I need to take. Mac Numbers is my go-to for charts for the moment.  Here a random slip stitch pattern is put on a knit ground that takes into consideration possible racking positions, with the ideal position for reversing the bend at the center of the chevron pattern. With a bit of planning, punchcard markings or even mylar ones may be used to help with tracking racking numbers for accuracy, but that appears lost using Ayab software

When planning for racking within the width of a piece, the racked columns will extend beyond the vertical edges of the knit. Since this is not about having zigzag edges but keeping the design within the body of the knit, the starting point and spacing for your ribbed stitches matter. Brother racking handle is numbered from 0 to 10. The numbering and direction of movement vary between KM brands. If you begin at 0, you are only allowed to move the ribber to the left, if at 10 the ribber only moves to the right. So that said, the racking sequence in the above illustration should be reversed, traveling from 10 to 0, and back. The green squares represent the direction in which the ribber stitches are moving, and the numbers in the column on the right represent racking handle positions. 

I found this slip stitch repeat produced too little detail in my swatches, but were it reduced for mylar use, it would remain 7 stitches high. It was taken from a punchcard book, so black squares/punched holes represent knit stitches. To match the fabric, in mylar use, the color reverse would do the job. The Ayab kit bypasses both the mylar reader and the programming capacity of the buttons on the left, so double height, double width, color reverse, etc. including the DBJ setting are planned for in the file import into the software. In some instances, Ayab settings (ribber for DBJ, and “circular”) do the work for you. I am using GIMP to create my BMPs. Paintbrush is a free program, still available for Mac, and functional including in High Sierra. It is the program used by some forum members to create their repeats, providing an easy alternative for people who not be used to working with image editing programs.

the slip stitch repeat in its original state: because slipped stitches create their texture on the purl side of the fabric, images do not need to be mirrored for the direction of the texture to be matched using electronic machines 
If the goal is to have the machine take care of keeping track of knit rows for you, without having to make changes in cam buttons, in the mylar a single repeat with blank squares programmed at the top and/or bottom of the repeat could then be knit using color reverse. Here the situation is similar to that of punchcard users who need to punch a hole for every knit stitch but considerably faster. If the original pattern is satisfactory,  planning for all knit rows as automatic needle selection can be done by color reversing the pattern in the software and adding all black rows in the image for download.  
some other all-over variations to try, individually, or even sequentially for slip stitch all-over texture

the first tests, for the various slip stitches, nothing quite “there” yet  
this is getting closer to the goal

The above working repeat and all above swatches were knit with the first preselection row from right to left, not left to right. For these stitches, the starting side does not make a difference. If the pattern, however, was in blocks that were even-numbered in height (2, 4, 6, 8), and the color changer needs to come into play for striping using it, accommodations need to be made so that preselection for row 1 happens from the right side to the left, toward the changer. The programming needs to be set to begin on the very last row, so the repeat returns to row one for preselection from right to left, and knitting rows 1, 2, etc begin with the KC set to appropriate cam buttons, to and from the left side of the KM.

The racking sequence needs to be adjusted to have the points of the zigzag land in the center of both the slip stitch areas and those in plain knit if that is the goal.  I am encountering needle selection issues with my hack, so this fabric is getting put to bed for the moment. In principle, the black squares in the illustration represent knit rows, and their number is easily enough adjusted in height. Punchcard users would need to punch holes for each black square, mylar users can fill in the white squares for a single repeat, add blank rows at the top or bottom, and color reverse when programming. In Ayab software, the repeat has to be drawn for the width of the piece but will repeat “infinitely” in length.

This is a possible punchcard template, with a shorter racking sequence. The Numbered column on left indicates the racking position. Pattern rows are preselected, so racking occurs prior to knitting across each row. I am also in need of purchasing more punchcards or another roll, so there is no test swatch at this moment. The top and bottom rows of punched holes on the colored ground are not part of the repeat, they overlap the first and last 2 rows of design in the punchcard, allowing the pattern to repeat in length. Ascending numbers swing to the left, descending to the right. Rows may be added at the level of #7 (7, 8, 9, 8, 7), so that the center of the swing may then occur on #9 positions in the racking handle, lengthen the card accordingly.5/14/20
Electronic machine models make experimenting easy and quick. Here an all-over tuck stitch is programmed for the base fabric, and racking variations are considered with the goal to cross the base fabric at various points in the patterned areas, or within the knit space alone. With increasing racking indicator numbers the ribber moves to the right, the shape its stitches create on the main bed moves to the left. With decreased racking indicator numbers the ribber moves to the left, the shape its stitches create on the main bed moves to the right. The repeat required mirroring for use in my electronic 930. Experimenting with racking intersecting tuck stitch on multiple repeat png, stitches were picked up on the ribber aside from the first tuck stitch on the right, A, on the center, B, and on the left, C, of the knit stitch groups.

 The tuck pattern tested, racking placed in the center position changing ribber needle positions
moving toward positioning the racked pattern further into the knit columns. Making the knit columns wider, placing repeats differently. The intended placement of the racked pattern is shown in yellow. Good notes and documentation of the final needle arrangement will make the technique easily reproducible. The needles involved on the top bed always need to be returned to the patterning position after any shares. At any point in the knitting, it is easy enough to transfer stitches on the ribber up to the main bed, drop the ribber down, and check on the placement of the racked pattern. If the place is satisfactory, the moved stitches can be returned to the ribber and the work is continued. If not, transferred stitches can be left on the main bed, other stitches can be shared with the ribber and patterning can continue with racking in the new location. One such adjustment is seen toward the bottom of this swatch. 

Tubular machine knit fabrics: fair isle, Brother/Passap

I recently came across this topic in yet another forum, so thought I would share some of my thoughts on it. The technique involves different patterns on 2 opposing beds. Table for 2 offered one option for programming 2 different knitting machine beds to achieve reversible DBJ or true tubular fair isle. I will be addressing Brother settings for the moment. Things to consider: the piece will be double thickness and 1.5 times the finished weight of one knit in single bed FI. FI technically knits 2 colors for each design row, the ribber at least one for the first piece here, so thinner yarn is probably best. If the main bed is creating a 2 color slip stitch, whether one color at a time (DBJ) or 2 colors together as in traditional FI, the fabric will be shorter and thinner because it gets pulled in by the shorter floats of yarn in areas that do not form knit stitches with that color. Generally, in FI it is good to have end needle selection on so that the second color gets caught at the edge, and the design does not separate from the rest of the knit at the sides. I knit my sample using KCI on the knit carriage. The ribber is going to knit one row for every 2 passes to complete each design row by knit carriage, so some adjustments in tension both beds need to be made for each side of the tube to be balanced. If the goal is to have the tube open at the bottom, I like to start in waste yarn and begin tubular while leaving a long end of the first color used so “bind off” can happen by sewing or crocheting the open stitches when the piece is done. The same can be done at the top of the piece, and both ends will match. Setting the needles point to point during tubular knitting will diminish any gap at the sides of the knit if the tube is made in the traditional setup. Since only one-bed knits at a time, needled will not come in contact even if directly opposite.

This fabric shares features with quilted fabrics, except there are no areas where the fabric gets joined to make pockets (needles on both beds knitting on any one pass of the carriages), the goal here is a continuously open tube. Minimal manipulation of carriage settings can be achieved in color separating for the specific fabric. My previous posts on quilting: 1 and 2, and on color separations for DBJ 

It is always best to start with a simple design that allows one to recognize needle selection. Long verticals can separate at their edges if knit a single bed, but I went for a simple pattern of squares to test out my premise and winged it. Thinking color 1 knit left to right, slip right to left and ribber slips when main bed knits right to left, knits when main bed slips left to right. The all blank rows indicate the main bed slipping the width of the involved needle bed. The same applies after any other consecutive color change. My mylar repeat, free drawn End the circular cast on/ waste knitting start and begin with opposite part buttons pushed in with COR; set change knob to select the pattern (KC I), to prepare for the move to left toward color changer. The main bed only will knit. With main bed set to knit <–, needles for the first row of the pattern are selected, but all stitches knit. The ribber needs to slip <– completing the circle. If in doubt, push up both part levers on the ribber.

the start of the tube, needle selection for first pattern row  

after the color change, with COL, change settings once more. The main bed will now knit to right and slips to left based on needle selection, while the ribber now slips to R, knits to L  (the goal here is simple stripe)

the start of a tube is evident if the ribber is dropped a bit the tube dropped off the machine the FI created on the main bed the pattern on the reverse, created by ribber

It helps to analyze the carriage actions on knitting the repeats. These charts illustrate the 2 colors knitting alternately with each pair of carriage passes. With any knitting motif, it is worth testing repeats consecutively in height and width to get a sense of what will take place using them on the finished knit. Here 2 lengthwise repeats are shown. The pattern could be planned to start the repeat with the area outlined in red on the right, and a full block would occur at the start of the tube. A bit of editing would make all rectangles equal in height.

So now that I have some blocks, what about other patterns and shapes? ……

In a previous post with exercises on DBJ, 2 separations of the triangular shapes below were offered. Testing the idea of using pre designed jacquard separations for knitting tubular fair isle, I chose to use the 2 alternatives presented. The related information is available in PDF format for punchcard and electronic machines

Here we have the motifs, and 2 methods of color separation for DBJ, charted, drawing each color design row only once

The middle image shows the method for separation achieved automatically in Brother by using the KRC button when using only 2 colors per row. It causes the least (if any) elongation of the motif. Each design row knits only once, programmed as is. If the KRC button is used, none of the other functions including double-length are allowed. The separation on the right is the most common color separation, actually knits each design row twice, which elongates the motif. As drawn, it would need to be programmed double length. If the knitting is representational, an adjustment may be needed in altering its height prior to downloading it for knitting. I used both separations above drawn on an old mylar for my second tubular FI attempt, sticking with my thin yarn, and working in small swatches while testing technique ideas. My initial premise was to knit each row twice using double length. The preparation was as already discussed. After the color change and resetting the carriages COL, the first row slips on the ribber, and the main bed knits the first design row in the alternate color, seen here in white. As in single bed FI, floats are created in that color between needles knitting it with COR, before traveling back to left for the color change, return all main bed needles back to B position with a ruler, ribber comb, or any preferred tool, so that only the ribber only will knit, keeping the knit tubular as you travel back to the color changer.

COL: change colors and repeat. Here are my trial tubes, again in too thin a yarn, but proofing the concept. My mylar was ancient, marked in #2 pencil on its reverse, and I can see a couple of spots that need darkening, but that is not a concern for this exercise

Adding color and expanding the charts to match the B/W versions each row elongated X 2what knits when setting machine for tubular; in the swatches, the blank rows were achieved by manually pushing needles back to B as shown above this shows what happens when the first separation is collapsed into what actually gets knit by the carriages in this technique
and the result in repeat in B/W like my swatch

Both elongated repeats are reduced to black and white squares below, with blank rows, included to let the carriage do the work, without having to push any needles back to B position, KC set to slip <–  –>. I often work out my separations in color, then fill the colors in with black and white. It is easier for me to draw the black only squares on the mylar or to enter them as pixels than trying to do that from a colored graph. I am now charting in Mac Numbers, no longer have access to Microsoft Office on my new Mac.

DBJ patterns predawn for punchcard machines or provided as charts for electronics may all be used for the FI pattern. The first separation method will yield a surprise. The second method if each row is illustrated only once needs elongation. In separations where the work is done for you, producing a result like the elongated swatch on the right, the pattern is ready to go.

Creating the separations by hand is time-consuming, having software separate the motif, eliminating that design time is quite helpful and more error-proof.

The ribber needle selection can be altered to produce patterning with hand needle selection, or by changing the slip lever positions as frequently as every row. That is a post for another day. That said, some things to consider: my own DBJ scarves often involve more than 1200 rows of knitting. The number of carriage or lock passes involved to achieve the same length is increased exponentially should I choose to knit the same designs tubular. If any needles on both brother beds wind up in work at the same time prior to the next row knit, the fabric will seal closed in those areas (another range of lovely fabrics, but not the plan here). For the ribber to knit in any other pattern than an easy stripe, one needs to either select needles by hand or add changes in levers possibly as often as every row. If multiple rows are knit on the ribber and then in turn on the main bed, one is actually creating a tapestry technique and there will be small slits at the sides of the knit, depending on the number of rows knit on either bed. It is truly helpful if the software in use or the machine’s console is able to recall the last row knit and to take you back to that spot if knitting is interrupted or put off for another day. That is one of the very convenient features of the Passap system providing the battery is still holding the charge. The latter also performs the same function and returns to the correct pattern row if one has to unravel rows and the number of unraveled rows is entered into the console. If long, nonrepetitive in length designs are in use and need to be downloaded in segments (wincrea has such limits), a warning noise when the end of the pattern repeat is reached would be nice to have. In my opinion, it’s fun to achieve things because we can, then it becomes a personal choice as to whether the process is worth it, and under what circumstances to use it.  My own accuracy when a lot of hand manipulation or other details are in use has faded with my increasing age and decreasing attention span. Others can tackle the same with great success, such as seen in some of the wonderful all hand transferred complex machine knit laces found on Ravelry, and then there was the man who used to tour machine knitting seminars with a MK sweater he had made for himself in a fine yarn that incorporated over 3,800 (yes, thousands) cables, weaving in and out of each other and in turn in and out of crossing diamonds in a fine yarn (no, no one I know of actually counted them, the count was accepted on faith).

The Passap console has built-in color separations for tubular knitting. As with Brother, the simplest fabrics are in one color. For one-color fabrics, CX/CX (the equivalent result in Brother happens by using opposite part buttons on either bed) is used on both locks.

For 2 color fabric, the DM 80 front lock (carriage term equivalent) is set on HX <– while if using the E 6000 one may select KT (knitting technique) 243, with the front bed set to LX (slip). I have had very limited experience with the DM80 decades ago, can only speak for the E6000. The front bed is programmed as for any other pattern. With the back lock set to CX (no pattern) or HX (pusher selection for pattern), the function is fixed, the front bed knits to left and slips to right, the back bed slips to left and knits to right to create the tube

Horizontal stripe: is the simplest to execute: set the back bed on CX, or put all back bed pushers in work position and set back lock to HX, no arrow key. Pushers up knit, pushers down slip. (in Brother set the appropriate ribber lever to slip in one direction)

Vertical Stripe: “automatic”, bring pushers under every back needle into one up, one down, alternating in work and in rest. Set back lock to HX, left arrow key <–, changing color every 2 rows. The same needle selection is in the same location with each color change, creating the stripe

Birdseye backing, manual tech involved/ lock setting change involved:  set back bed pushers alternating one up, one down, thus alternating in work, out of work. Knit 2 rows with the lock on HX, no arrow key, and 2 rows with the locks on HX <–.

Solid color backing is possible: set the front lock is set to LX <–” (slip <–”). When Tech 243 is in use, after the setup rows are completed, the console gives the prompt for setting up the pushers, all in work, and for HX <–”on the back bed. The result is that for 2 rows in the lining color, stitches knit alternately on each bed. The front bed then knits alone in turn for 2 passes;  the color yarn in use creates a float the width of the knit as the locks return to the right, making it the least acceptable variation, and an unbalanced knit. The set up is different for both quilting (BX <–/LX)  or solid color backed DBJ from tubular FI created in this manner.

My Passap manuals have been well used, often technique numbers are surrounded by notes in my scrawl. Techniques perform the color separations for the specific fabric, the accompanying diagrams and directions are suggestions for swatches provided as well in the alternate accompanying manual. Lock settings can be set to suit i.e. tuck substituted for slip, etc. The separation is fixed, but all lock settings are in the hands of the knitter.

2 color circular tucked designs are produced using techniques 162-165, with the frequently unfamiliar settings using OX/DX. As with many other techniques, some may be used with stitch patterns, some not, but if you understand what is happening front bed patterning could be converted to the automated pusher or needle selection by entering a planned color separation as a pattern. OX is a combination, tubular tuck setting, paired with DX. OX is a combination of KX (tuck in the pattern) and CX (circular). DX is the tubular tuck setting for the back bed. OX and DX will knit needles with a pusher (needle selected on Brother) in work (selected needle), and tuck on needles with no pusher in work (non selected needle) moving from right to left. From left to right the front bed is not knit any stitches (contributing to making the fabric tubular). The back bed knits only from left to right, the second side of the tube. E6000 technique 185 with locks set to N/OX will produce tubular FI with long stitch.  For three and four colors where the colors are separated at one row per color  use technique 252, locks set to N/OX. Superimposing patterns for three and four color techniques require entering card reader techniques. With my cable set up, when I was experimenting with reader techniques eons ago, I believe I was successful downloading the pattern for the design from the PC, and entering the card reader technique as a second pattern, via the card reader. I have never tried doing so with additional software, and shy away from any situation where I have to enter commands to get the software to work.  Out of the group, 162 is the only one that can be combined with a stitch pattern. The console gives cues as to when to change lock settings, with some thought similar fabrics could be knit on the Brother KM. The techniques, and my notes, which at this point would need some self-interpretation. The UX scribble is in reference to a fabric that slips over needles with pushers selected down from right to left, then tucks over needles with pushers selected down from left to right. Needles with pushers up will always knit. In Brotherese the pattern is knit with opposite function cam buttons in use slip <–, tuck –>. It will not produce a tubular knit. Worked out patterns for such fabrics were included in some of the Brother punchcard pattern books. 
For tucked 2 colors fair isle use technique 185 with lock set on N/OX. 

 

Bowknot/ Butterfly stitch on the machine

A recent Pinterest post got me searching out some of the fabrics in this group. In hand knitting, floats creating the butterflies/ bowknots are usually apparent on the knit side. For two such patterns please see http://www.knittingstitchpatterns.com/2014/11/butterfly-bowknots.html

http://www.knittingstitchpatterns.com/2015/04/butterfly.html

https://handlife.ru/vazanie/obemnyy-uzor.html caught my attention. Here we have a combination of knit and purl stitches, with floats formed on the purl side, making the fabric or a “cousin” of it possible on the machine This is my first experiment with gathered slip stitch floats on the purl side of the knit. To begin, this chart indicates one punchcard pattern’s full repeat in width.  Four repeats in length would be required (the punchcard minimum repeat in length to achieve smooth continuous card feeding is 36 rows). Punch out blue squares, leaving white ones unpunched. A single repeat (outlined in black, 8 stitches by 12 rows) is for use in electronic patterning, where one may alternately draw or program white squares, then use color reverse.  The red line represents 0 needle position in Brother KM

Pitch on H5, ribber needles are centered between main bed ones, so the “knot” width, represented by white squares, can be even in number. Begin with the first needle left of 0 (red line) in the work position, continue across ribber bed with every 4th needle in work

The main bed knits in a slip stitch pattern for 4 rows, then knits 2 rows across all stitches. Floats are created every blank row throughout, composing the knots or butterflies. The ribber is set to knit (N,<–>N, will pick up stitches only on selected needles.
The fabric is a slip stitch one, so it will be short and narrow. That is something to be considered when planning cast on, bind off, and beginning and ending edges of the piece.
In Japanese machines, a ribber comb is recommended. If casting on the single bed, start with waste yarn, poke the comb through that, and proceed as you would for any other rib fabric.

My sample is knit on a 910, with white squares drawn. This is what happens when you forget to color reverse. The all-blue squares now became “white”, so those 2 rows were slipped, not knit, bringing float repeats closer together the result with color reverse working out a mylar, electronic (unless DM 80 40 stitch width is in use) repeat for a variation of the fabric knit single bed. The stitch count is odd,  allowing for a center stitch manipulation. KCI is used to make certain the first and last needles knit on each side. Floats created close to edges may be left without hooking them up. The fabric separates slightly along the “bowknot”  edges because color-reverse is used, blue squares in chart slip, create floats when Rows 6 and 12 are reached respectively, that single square becomes a non- selected needle, and pick up those floats with any preferred tool lift them up and onto that single non selected needle, push that needle out to hold
with the next pass the single needle and loops knit off together and become part of the alternating all knit block in the design
the swatches are knit in a 2/15 wool, the fabric might be better served using a thicker yarn. Here the “blocks” creating  “floats” are side by side

For another single bed cousin in different weight yarn, please see the previous post 

Fabrics worked on the single bed with groups of pulled-up stitches on the purl side will have some distortion of the stocking stitch side depending on the weight of yarn used, the number of rows hooked up, and stitch type. Working on the opposite bed to create the floats produces a more balanced fabric.

My charts often evolve. This may be done on graph paper if there is no access to the software. I began adding a space between each block, thinking about those knit stitches I wanted to create on the purl ground, hooking stitches up on red squares adding border stitches, and more theory on the placement of stitch type
the result places “knit” stitches in the center of butterfly (magenta arrow), not at its sides, and I see and extra purl stitch (green arrow). Multiple stitch-wide borders create unwanted floats on one side
back to the drawing board and working things out first as a hand technique

I began with my carriage on the right (COR), after setting up the repeat on a multiple of 6 stitches +3 as indicated above. The last stitch on either side on both beds is never transferred, and the short loops of every other set (rows 5 and 17 in the chart) are not hooked up. This will produce a slightly rolled edge on each side. The larger number of border stitches becomes problematic. The photos were taken while knitting 2 different swatches, so needle tape markings are not the same in all photos. To produce the circular knit, opposite part buttons are pushed in so with carriage on the right (COR), the settings would be

Cast on in any preferred method, ending with all stitches on the ribber Configure main bed needles as illustrated in a stand-alone setup row at the bottom of the chart With carriages traveling from right to left, the main bed knits on those single needles, creating floats between them and the ribber slips. When carriages travel from left to right, only the ribber knits, and the main bed slips. Here the carriages have traveled to the left, and back to the right 
With row counter (RC) set to 000 at the start of the knit, hand techniques occur on RC 5, 11, 17, 23, 29, and so on. Hooking up loops and transferring stitches between beds always occur with carriages on the left (COL). On those rows, the floats are hooked up on the center needle of the 5 empty groups. In this photo, the ribber is dropped to show what is happening on each bed. The last stitches on each bed are not moved, and those short floats, when created on completion of alternate repeat top halves, are not hooked up after the three floats have been hooked up, with COL each time, the in-between main bed stitches are transferred back down to ribberCOL: be sure when hooking up floats that all in the series are picked up. The space between the beds is fairly narrow, and the tool used is purely preference-based. Shifting the main bed needles forward will provide a visual check for loop count as you go. I bring needles with multiple loops out to hold before transferring to the ribber, and then also the transferred stitches on the ribber out to hold to ensure they will all knit on the next pass from left to right. Patterning occurs on every 6th needle on both beds, except border stitch groups

this is the needle arrangement/position in my final swatch, knit in 2/8 wool, COR

So what can be automated in the process? The knit bed needs to work the stitches that form floats every other row, while the card or mylar need to advance every row. Trying patterns out as an all-hand technique helps determine tolerance on the part of the machine and the degree of patience available. With thinner yarn, the fabric would be more compressed, and maneuvering stitches more frequently to achieve similar finished size knits, so I switched to a thicker yarn. I found more than 3 rows of floats were too hard for me to manage successfully.  “Air knitting” to determine the placement of knitting on any bed before patterning helps determine the number of needles in use, especially if edge needle placement or count matters: here is the first pass using my mylar  eliminating needles to any desired width, leaving only one needle in work on each side of selected needle each bed for this fabric reducing main bed count so only one needle is left on either side of a selected one that needle (green arrow, gets transferred down to ribber now the number of needles involved on both beds is evident on both beds

While knitting in the pattern the ribber pitch is set on P (point to point) to keep stitches on opposing beds centered (P pitch also makes it easier to transfer directly from one bed to the other). If the cast-on is for every other needle rib with stitches then transferred between beds for pattern knitting set up, the cast-on and all rib rows need to be knit in H pitch, with a switch to P for transfers and knitting in pattern to be completed. With the first row set up on the selected segment of the needle bed, there are additional steps to take.

This is my working repeat. Since it is 6 stitches wide, it could be worked out on a punchcard, punching out all black squares. On my mylar, I marked yellow squares only, with no color reverse
To work consistently with the method described in the larger chart, the first row was manually set up on both beds preparing for the pattern with COL: change knob set to KCII (cancel end needle selection, not every needle in work on the main bed), KC set to slip <–>, so non selected needles slip with each pass of the carriages, advancing the mylar or card one row. The ribber set to N/N or as below will knit from left to right. Pre-selection row is made traveling to the right, ribber only knits

With COR: set RC (row counter) to 000. Make certain proper part (slip) buttons are engaged. MB knits in the pattern based on selected needles, ribber knits when moving from left to right. The fabric is tubularHand techniques will now also occur when carriages are on the left, on RC 5, 11, etc as described in the hand technique chart, on rows with no needle selection. As in hand tech, transfers and multiple loops containing needles are brought out to hold before moving the carriages from left to right and selecting the needles for the next set of floats with that same pass.

This is my resulting fabric, hand tech shown, the short mylar test above was cropped

A return to Brother ribber and DBJ settings

I have recently been asked about DBJ on the bulky machine, ribber setting options are offered at the bottom of this post. More to follow.

Ribber settings vary from one brand of machine to another. Here is a review of the Brother carriage features

Back in 2015, I wrote on quilting on the machine, using the carriage representation below. Here lili buttons are positioned for use

I no longer have Adobe programs available to me, for this post my images were created in Mac Pages. I have simplified the illustrated button and cam settings in red.

I tend to knit most if not all my rib fabrics with the slide lever in the center position (marked lili on the carriage, blue dot). This avoids accidental changes when altering the settings for sections of garments or forgetting to reset it ie. if one uses a ribbed band in a sweater front on one setting and accidentally uses a different one in the back, there will be a difference in width and height between the 2 bands that can be quite noticeable, and is not apparent until the garment pieces are completed and ready for seaming.

If you prefer to start with a 2 X 2 industrial rib, arrange needles to give a neat join at seams, plying yarns may again be required to give the rib more body. racking cast on may be used, avoiding transfers between beds after an every needle cast on Diana Sullivan shows one method of working and illustrates needle arrangement and transitions to main bed knitting well. Alternative needle setups:

I personally never do 3 circular rows after the first cast-on row: it will produce floats on one side of the rib, which may be noticeable in your final fabric on one of the 2 garment sides.

To close holes when transitioning to garment pieces in other than every needle ribs, rack the beds one full turn, knit 2 rows, rack back again, and proceed as needed for the desired fabric

The lili buttons on the ribber are representations of every other needle set up, akin to the 1X1 card use on the main bed. It is essential for an even number of needles to be in use when the lili buttons are in use (pushed in, and turned toward the lili markings on each side of the ribber carriage, R to R, L to L). An easy way to ensure the even number is to look at the needle tape markings, which alternate between dashes and blank spaces between them. A line/ dash and space make a pair, so if you start with a needle on a line, the last needle on the opposing side needs to be on a blank space or vice versa. The holding cam lever remains in N position throughout these illustrations.

simple rib 

Setting for slip stitch: raising levers to P position will result in stitches slipping when the ribber carriage moves in that direction

slip to right slip to left slip in both directions

Setting for tucking on ribber: it is possible to tuck on every needle on either bed when knitting every needle rib, as long as the needle on each side of the stitch forming the tuck loop on the opposing bed is creating a knit stitch, anchoring down those tuck loops on each side.

tuck to left tuck to right tuck in both directions

Double bed patterning DBJ
The most balanced fabrics are achieved when no more than 2 colors on any single design row are used, and the number of rows knit on the ribber total the same as the number of rows knit on the main bed. It is possible to knit designs with 3 or more colors per row. With Japanese standard machines, this would require a color separation, automatic ones are limited to 2 colors per row (Passap built-in techniques have a range of other options). The more strands of yarn, the thicker and heavier the fabric, with distortion in the aspect ratio of the design. As with single bed fabrics, double bed slip stitch creates knits that are short and skinny, tuck creates short and wide ones. As stitches slip, tuck, or get longer there will also be “bleed-through” of the alternate color on the front, “knit” face of the fabric. In small, balanced repeats this can create a color mix that may make the result either interesting or confusing. Garment swatches need to be larger than usual for when knitting single bed. I tend to use at least 80 or 100 stitches/rows on both beds to calculate garments.

When using no more than 2 colors per row, Japanese machines offer the option of a color separation that knits one design row per row, which is an added way to reduce motif elongations in the finished knit. Passap knitters may use tech 179 to achieve the same result. For different separation methods for double-bed fabrics, see color separation posts on them.

Brother lili buttons: illustrations found in brother manuals for their actions, an even number of needles in work on ribber is required

bird’s eye (lili <-   ->): this is a common type of slip stitch. One pass of the carriage causes every other needle to knit. As the ribber carriage moves back to the starting side, the alternate needles knit, producing a single row of color. This helps double-check on the color used on the last row knit when knitting is interrupted on the color changer side. When knitting in 2 colors per row the fabric is fairly well balanced

tucked bird’s eye backing (lili <-   ->) with slip pattern on MB: if no cam buttons are pushed in on the Main bed, and the carriage is set to normal knit with no pattern selection, lili buttons on ribber will behave as though the 1X1 card is in use, no elongation or other changes are possible without changing levers manually as often as needed

tucked bird’s eye backing (lili <-   ->) as above, with main bed set to tuck the main color and slip the contrast, requires manually resetting cam buttons with each color change, or alternately tucking the main color, knitting the contrast

color 1                                            color 2

striper (double) backing: fabric is unbalanced, twice as many rows of ribber stitches as main bed ones, the design is elongated, but the fabric is softer and more flexible

single (half) striper backing: fairly well balanced. The ribber knits only one row for each 2 passes of the carriages, so for 2 colors again, there are no extra rows knit. Part button on ribber may be engaged on either side tubular: either pair of opposite part buttons used tucked half Milano: when using tuck/slip combinations opposite cam buttons are used i.e. if right tuck cam button is pushed in, then the left slip button is also main bed <–> tucked jacquard: each needle on the ribber knits every row. Needles on the main bed knit in pattern according to punched holes, black squares on mylar, or programmed pixels. Non selected needles tuck. The patterns produced on the backside of the fabric are almost the reverse images of the front. Because so many tuck loops are formed the fabric is “short” and very wide, so cast ons and bind offs need to be planned accordingly

variation: tucking the main color, knitting the contrast, manual cam button reset every 2 rows

solid backing: the part buttons on the ribber are reversed manually on the left side of the machine when the color changes are made. The solid backing color knits on the ribber when both part buttons are down (N<–>N), the second color will be slipped with both the part buttons in the up position.  For an interesting effect use wool for solid back color 2,  other fiber for color 1, and felt the result.

2 rows color 12 rows color 2 (solid back color)

See altering a sinker plate for producing this fabric using a second KC to knit rows only on the top bed, no ribber setting changes required.

tuck/plain combo: requires manually changing cam button settings on the main bed every 2 rows, change knob remains on pattern selection setting

2 rows color 12 rows color 2

no automatic patterning on the main bed, change knob on N for English or half fisherman rib: tuck every needle either direction on ribber only

full fisherman rib: tuck every needle alternately on both beds, in opposite carriage directions (below = L/R, or use R/L)

Vertical striper backing and “ladder-back” variations involving some hand manipulation and selection of needles in work are also alternatives for DBJ backing.

I have for decades and in my posts referred to this part as the ribber sinker plate; technically it is called the connecting arm in the Brother literature. There were slight differences between model years for them as well. Later connecting arms were branded with the number 2, earlier ones were not.

For knitting DBJ with the unmarked connecting arm, it was suggested in later manuals that an accessory be used: the result with the plate in place is a change in the height of the metal from the needles with stitches in work as seen below with the plate secured in place

Revisiting drop / release stitch lace 1

Hand knitters may be familiar with drop-stitch patterns where the yarn is wrapped multiple times around the knitting needle, followed by knit stitch(es). On the next row, when the wrap is reached, the extra wraps are dropped off the needle, and the remaining single loop is knit in a regular manner. On the knitting machine this technique is called drive and mesh lace, release stitch or summer fair isle by Passap, and drop stitch lace in some of the pattern books. Drive lace typically has lines of patterning where loops are formed between rows of all knit stitches. The main fabric, stockinette, is knitted and produced by either bed. Selected needles knit pattern stitches on the other bed for one or more rows, then are dropped from those needles, unraveling back to their starting point, creating the larger, open stitches. Sometimes a distinction is made between terms used, in drive lace the bulk of the punchcard is left blank, and there are far fewer marks than in drive lace. In mesh lace the balance of holes to punched or blank areas is 50/50 or more punched areas than blanks, often the “holes” or black squares are side-by-side.
Drive lace marks out the shape of the pattern, mesh forms the background. Blank rows across the width of the repeat allow the knitting of plain rows between dropped stitches including ones, separating the series of holes, or stabilizing the fabric.
Both types of mesh may be combined in the same fabric, with dropping planned on the same rows. The diamond on the left represents drive lace, and the one on the right is a mesh version. On the right, solid “lines” echo the shape. Repeat is suitable for punch cards but may be altered to suit both cards and electronics. revised with fewer single dots, and solid lines in the ground The fabric may be created both as a hand technique or using automated patterning. In sources that show loops being formed on the ribber, stitches are released by uncoupling the ribber carriage and moving it across the knitting and then back to its original spot, thus dropping the stitches. In Studio machines the P carriage may be used to drop stitches, see previous posts on modifying one for use on Brother KM.
The tension setting on the patterning bed affects the loop size and its tension is frequently one to three numbers looser than the all-knit bed tension. In Brother machines, the ribber knits at a tighter gauge than the main bed, so take that into consideration and adjust it when knitting all knit rows on every needle on the ribber, where the tension may need to be loosened one or more numbers than when knitting same yarn in stocking stitch on the main bed. Matching tension numbers on both beds may provide enough of a difference in stitch size for loop formation. The difference in gauge between the beds also merits calculating adjustments when knitting in circular or U format.
Releasing stitches may happen after every pattern row, after groups of pattern rows (such as bubbles or check patterns), or even at times when knitting is completed. With groups of pattern rows, I have had better results with more frequent stitch releases. Two types of mesh can be created. Stockinette mesh has an equal number of rows on both beds. The result is enlarged stocking stitches along with narrower, single-bed ones on any one row. Half Milano mesh has a horizontal ridge on the purl side with 2 rows knit on the all-knit fabric bed, to every one row on the patterning bed. One of the rows has the patterning bed slip every needle, with the ribber only knitting, the second row forms the combination size stitches as discussed previously. In patterning in Brother KMs, this would need to have such rows added to the programmed design. The fabric is a bit more “stable”. Passap offers multiple techniques for dropping stitches, often referred to as summer fair isle, and using 2 colors per row. Different looks are achieved by changing the built-in technique number, as well as when using a stitch ditcher on every row knit, as opposed to using empty passes of locks to drop the stitches.

Working with positive and negative space variations: the repeat is suitable for any machine, my sample is executed on Brother KM. Since alternate, all blank rows have no needle selection, before knitting that row (ribber only will knit), dropping stitches knit on the main bed on the previous row will not alter the pattern using any method you prefer, set up knitting so all stitches are on the ribber. If you prefer to set up complete repeats prior to watching, “air knitting” prior to ribber set up or using the position option on the main bed if that is available, will help achieve that set knit carriage to KC II (used when patterning does not occur on every needle across the needle bed), both part buttons pushed in for free pass to the opposite side of km, no knitting occurs but the first row of pattern knitting is selected. Ribber is set to N<–> throughout the carriages now move to the opposite side, selected needles on the main bed pick up loops, and nonselected needles stay empty. Ribber knits every stitch using a ribber cast on comb, stitch “dumper”, or another tool, move needles holding stitches forward to drop loops, and return empty needles to work position (B)as carriages move to the opposite side, needles are selected for next row of knit stitches to be knit on main bed carriages now move to the opposite side, loops are picked up on selected needles all needles are now not selected, above stitches/ loops are dropped, needles are returned to B position before the next carriages’ pass carriages move to the opposite side, selecting pattern needles carriages move to the opposite side, picking up loops before carriages move again, drop stitches formed. Watch loops after they are dropped, if tugging knitting it is not enough to pull them out of the way of needles returning to patterning, take a tool, or something like a credit card. Slide it from one side to the other between the beds, thus keeping loops clear away from the main bed

In summary; assuming one is starting on the right side of the machine COR
step 1. <-  the carriages select needles that will form loops
step 2. ->  the carriages knit, picking up loops
step 3. drop the loops just formed, returning all empty needles to the B position
step 4+ repeat 1-3 for the entire length of the piece
My sample was knit in slightly fuzzy wool. Smooth, thinner yarns result in longer stitches whose patterns get read more easily. Because wool has “memory” the vertical edges tend to roll to the purl side and return to rolling even after heavy pressing and steaming. There are a couple of spots where no long stitch was created due to markings on the mylar not being dark enough.
Other things to consider: this fabric widens when blocked, so cast on, bind off, and beginning and ending edges need to accommodate that. This particular design creates a fairly balanced fabric. In many drop-stitch fabrics, it is recommended that edges contain stitches dropped in the pattern in order to maintain vertical length at the edges. To achieve that, the first and last needles on both sides should be on the main bed. That said, having an all-knit border (stitches knitting only on ribber, no dropped stitches) may work well in your pattern, or pull edges in too tightly when compared to the all-over motif released repeats. Testing on your swatch can be achieved easily by simply taking some needles on the main bed out of work on one side, thus creating the “all-knit border”. The latter can happen by accident if not all needles are returned to the B position properly after dropping stitches.

It is possible to produce a drop stitch pattern on the bulky machine or depending on the yarn, knit with heavier yarn on EON on the standard machine. The resulting “patterns” happen with varying the number of rows used to knit in each color, which has not been addressed in previous posts. I prefer to use patterning on the top bed to select needles, but this pattern may also be knit as a hand technique, using the ribber to produce the loops that will be dropped. This page from the ribber techniques book reviews the baseline process and settings

purl side is shown first for each segment, followed by its knit

Punchcard knitters are not excluded from creating these fabrics. Some punchcard sets supplied with machine purchases were published for Silver Reed Machines, two such sets are available for download ie. Silver Reed-Singer R-2 Standard Punchcards For SR360 Ribber and the same in a 30 stitch version making them suitable Silver Reed-Singer FRP70 30 Stitch Ribber Punchcards. One such card easily translates to one color drop stitch. Changing fiber content affects the scale of resulting patterns and the size of the dropped stitches, the yellow sample was knit using a wool rayon, and the purple cotton used the same tensions. If using punchcard machines, factory issue punch cards provided with the KM may be usedPlaiting is also possible, but depending on the color choice the pattern may become muddied A slip stitch edge may be planned to keep edges of items such as scarves from rolling consider top and bottom edgings that include the technique (illustrated in the previous post) Adding complexity: dropped stitches may be combined with other stitch types, shown here in combination with tuck stitch on the main bed, dropped loops created on the ribber. Stitches are transferred up to the top bed. The KC is set to tuck, the ribber episodically picks up loops across the whole row, and they are dropped on the following pass; it is then set to slip when the main bed is returned to tucking An alternative way to produce this fabric on Brother is to use the knit carriage with no yarn to do the “stitch ditching”. The basic design programmed into any brother machine, electronic or punchcard will need to be altered. The intended design in my sample is a 4 X 4 square, colors represent what would be punched holes, black squares, or pixels. Simple block patterns such as these may be released upon completion of each “square” series, in this case, after 4-row segments. Two rows are added at the top of each “square”, one repeating the motif width, the next completely free of any markings Rows 5 and 6, 11, and 12 are not part of the original repeat. The 5th design row provides needle selection, traveling from right to left. When the carriage passes in turn from left to right with no yarn, those preselected needles will drop while preselecting a blank design row (6) that allows the carriage to return to the left-hand side. As it moves back to the left, the carriage will preselect the first row of the design. With COL yarn is picked up in order to knit the next set of dropped stitches. A color change may be made while the carriage is on the left.
Begin with all stitches transferred and in the work position on the ribber only. Every needle will be in work on both beds for the remaining fabric. The ribber half-pitch lever is on H. With COR set the change knob to KC, preselecting from right to left for the first row to be knit after pushing both part buttons. This allows the KC to travel to the left without forming any loops or stitches, but the preselecting first row of the pattern. Change color if using more than one color, knit 4 rows. color 3 (or 2) can be an empty feeder. Change to color empty so yarn(s) in use are held until picked up again and there is no yarn in the ribbers sinker plate yarn feeder. There are 2 options for dropping stitches. One is to disengage the KC from the ribber, it will be picked up again as you move into the color changer to pick up the yarn once more. The other is to keep the carriages paired, set the ribber to slip for 2 rows, then back to knit as you return to the color changer, pick up the yarn again, and continue to knit. If row count is important ie in making a garment, the row counter gets turned off for the 2 rows when stitches are dropped, remember to turn it back on when knitting the next 4 pattern rows. I personally find this fussier and more error-prone than other methods I have described. My swatch is knit in acrylic thin yarns and lightly steamed, so bubbles have flattened out considerably. The fabric is related to that shown in the ribber techniques book, page 23, created by picking loops up from the ribber combined with racking.
This is my ayab repeat, this time executed by configuring the knitting to begin on the last pattern row 16 for that first preselection row from left to right instead of altering the repeat itself More to try: the typical appearance to look for in the source inspiration is that of single-row horizontal geometric designs with all blank rows separating them from each other.
Studio pile knitting patterns such as those found in may be used as published. It may be worth color inverting or spacing out the designs with many more white squares in between the motifs for more recognizable designs in the dropped stitch areas and for a more stable fabric in repeats such as these. On rows where there are no punched holes, resulting in no preselection in Brother machines, stitches are dropped prior to moving the carriage for preselection of the next row of patterning. The results are easy to test and amend. One such pattern: the original repeat The yarn used here was a softly spun rayon that began eventually to split, and get partially caught up on gate pegs, leading to the ending of the swatch Switching yarns made knitting easier and quicker to produce, planning for a different sort of wave, an amended version of the original design was used Fair Isle
a 24X60 design repeat was randomly chosen and used double length The first pattern row will pick up loops on the top bed, using any tool, drop the loops and return empty needles to the B position.
The next pass will drop the stitches and preselect the next row of loops.
Knit to the opposite side again picking up loops, drop them, return needles to B, repeating the steps.
The knit grows in length very quickly, the side edges and cast-on and bind-off methods would need more careful planning in a final project.  On electronic machines, the repeat can be adapted to yield more knit stitches between the flower forms
Beginning with a 23X31 isolated motif,  the shape is expanded to 30X36,   and two potential dispersals with the flower drawn in symmetric repeat in width and height X3  Transfer lace patterns: use patterns that have at least 2 rows knit between repeat segments. The results are likely to be subtle. On electronic machines: cast on as preferred, transfer MB stitches to ribber, where all stitches will be knit on every row. The main bed will be knitting the stitches that will be dropped, the lace carriage will not be used. As the carriage moves across the bed selected “lace” pattern needles will be knit, and the non-selected ones will be skipped. Program the pattern in the usual manner. Set the change knob to KC II to cancel end needle selection, the knit carriage to slip in both directions and continue knitting until all needles are in the B position. At that point disconnect the main bed and ribber carriages, unthread the yarn or have it held for you in the yarn changer. Set the main carriage to knit, move across needles in B, dropping them since no yarn is in use. Bring the disconnected carriage across the knitting again, reconnect to the ribber carriage, and rethread. Set KC to slip again, repeating the process. As an alternative for dropping stitches, leave KC set to slip, and push all needles out to hold. With no yarn in the feeder, any loops will be dropped. Make the 2 passes with KC only as described, reconnect carriages, rethread, and continue until no needles are selected again.
If on an electronic machine with 2 knit carriages available: the number of rows is usually an even number, so an additional knit carriage with no yarn could be positioned on the opposite side to the one selecting pattern, set to do plain knitting, holding no yarn, and it may be used to drop the stitches on “plain knit rows” on lace card without requiring the other additional steps and cam button changes.
Tuck and drop: use color reverse if appropriate (black squares for knit stitches, white for tuck) set up as for other drop stitch fabrics, choose patterns that are broken up by 2 rows of plain knitting between the tuck rows. KC II is used once again. Since in such cards, you one is working with punched holes or black squares, the empty knit carriage alone may be taken across with no yarn, dropping the complete, all knit rows. It is not necessary to change the knit carriage setting from tuck to knit to do so.
Tuck is an alternative option for a free pass as well, realizing that helps avoid errors in patterning by missing resetting the cam buttons between the two functions.
Racking patterns:  a few variations are suggested in Brother punchcard volumes. Sometimes translations are what can be described as interesting. One such pattern Yarn choice as always can make a good deal of difference, here a wool rayon was used. The zig-zags would be more visible if worked using a larger number of all-knit stitches

 

Double Jacquard and color separations: some previous posts, links, hints

A recent forum discussion on DBJ on Ravelry led to my looking back on some of my previous posts. Some of the features in both excel and numbers changed over the years, but most basics remain. Program-specific or a “software” general search in previous posts touch on GIMP, other programs, and other fabric design choices.

Ladder-back ribber settings illustrated (no actual pattern knitting involved), 2018/02/09/ladder-back-double-jacquard-backing-variations/

Double bed jacquard knitting allows for designing knits using multi color patterns without any concern for floats.
The ribber and a double bed color changer are necessary.
The ribber causes the floats to be knit into a second layer of fabric on the ribber side, hence the term double knit.
Only one color may be knit at a time.
Most color-changers only accommodate 4 colors, so in creating separations for double jacquard, this tends to be the maximum number for separations.
The more colors one uses in a row of knitting, the more all the stitches on the face of the fabric must stretch in order to accommodate the colors laid behind in the backing fabric.
The more the stitches on the front face of the fabric must stretch, the muddier the look of the design, with additional bleed or grin through of the backing colors through the stretched stitches.
Color separations are required.
The method of separation depends on the knitting technique to be used, the knitting machine one own and its capabilities, the desired look of the finished piece, and the time one wants to spend working on the separations.
Two of the most common backings are the striper technique, where the ribber knits horizontal stripes and is left set for normal rib throughout, and birdseye, sometimes called tweed or checkerboard, only achievable in ribbers with 1X1 needle selection.
Both techniques may be knit with tuck or slip cam settings.
The more colors per row the denser the fabric and the more grin/bleed throughwill be noticed on the knit side.
Separation Methods:
Method 1/A: always works. Knitting in this case occurs for one design row at a time. The knit design row 1 will need to be expanded into 8 rows of knitting.
The separation in the first chart must be elongated X 2 in order to make passes to and from the color changer.
The result is likely to produce elongation in the image, regardless of the backing method used.
In Japanese machines, one usually performs the first preselection row away from the color changer when using the automated color separation for 2 color dbj, KRC. Here the first preselection row is made toward the color-changer since each color will knit twice.
Passap is a bit different. In addition to its 4 color changer being on its right, the first pass to the left aligns pushers and needles, the second pass to the right preselects pushers for the first row to be knit after the color change on the right. The original design may have an even or odd number of rows since each row will be knit twice.
The results from this chart do not need to be elongated, each design row is expanded into 8, with each color knitting twice.  In Method 2/B: the separation occurs in two-row units.
The carriage passes twice with each of the four colors.
One row of the design is knit going across to the bed, with the next row of the design knit when returning to the opposite side.
The ground color is split to the beginning and the end of the sequence.
In Brother the first preselection row is made moving away from the color changer.
The first pass back toward it should fill in the majority of the needles.
When the last row is reached, the color is changed back to the ground color
Row 2, the carriage will be on the right, heading back to the color changer as the sequence is completed.
The expectation is that the ground color, 1, will knit the majority of the needles. The separation sequence is repeated for each design row.
With the majority of needles knitting the first and last pass for each row one, in theory, the next pass will be knit on a row where stitches will not be attempted to be formed over a space not knit in the previous row, resulting in dropped stitches. Method 3/C: is similar to Method 2, but the ground and background are not split into the first 2 rows of the graph.
This is the hardest to achieve in terms of knitting without errors in patterning or dropped stitches, it also reduces elongation of the design.
The main color knits for 2 rows before the other colors knit, which may alter the availability of needles required for placement of the stitches in the next color row.  In both methods 2 and 3, the design must have an even number of rows.
Method 4 is based on color layer separations. Machines such as the E 6000 allow the knitter to superimpose designs (rules for order may vary) and offers techniques for then performing the separation for the knitter, usually as seen in Method 1, lengthened.
There are Passap published reader techniques that will allow for the single pass for each color per row for 3 and 4 colors designs.
Any error-free hand separation for a pattern may be knit using the slip stitch setting, with appropriate DBJ color changes. The same pattern may be downloaded into the E6000, in turn, using Technique 129, color reverse, with the front lock set to LX.
The size of the motif for automatic color separation is dependent on the available Ram and the knitting machine model.  This is a copy of one of my handouts when teaching DBJ eons ago Another former handout, intended for Passap knitters. Many of these fabric options could be emulated on the Brother machine, if separation method 1 were available, with a bit of interpretation. A machine knitting cross reference chart Automated color separations preparations for download happen easily when using Ayab and img2 track software and accompanying cables. In addition to the familiar built-in KRC separation, there are a variety of other options. For more information please see

Revisiting knit “bubbles” brother KM

Sometimes months or even years go by before I revisit previous posts. As I review the information, it may occur to me to think about it further, and /or to present it in a slightly different way. I find it hard to believe how much time has passed since 2013/09/06/more-knit-bubbles/ got published.  Here is another way to look at the fabric on Brother KM. Since I knit on a punchcard model or a 910 electronic one, I will refer to pattern repeats in terms of punched holes or black squares.

Bubbles and drop stitch lace share some of the same principles, the effect is created by stitches that are larger than others. Slip stitch setting can be used to automate needle selection. Black squares or punched holes will knit, unpunched areas or white squares will not, with needles left in the B position. Brother preselects needles for the next row of knitting, so when combining hand techniques with needle selection, one has the option to intervene before the next row in the design is knit. Using the card or mylar to read row 1 of the design helps determine where on the needle bed to set up your repeats. In this instance, the ribber knits every stitch, every row, with one extra needle on the left (or more on each end if preferred) in addition to repeats # required to achieve the desired width. All needles are in work every row on both beds. Main bed knits in response to programming.
Working in multiple of repeat -1 on the top bed, plus one needle in work at each end on the ribber. Considerations need to be made to align the design properly. The markings on my metal bed are from a different project. The goal is this needle arrangement “air knitting” with carriage set to KC will help identify patterning repeats. Groups of 7 include a needle on each end which will be pushed back to A position in the body of the knit/ NOOW (needle out of work) indicated in the chart for the main bed needle setup the first selection row a needle on either side of the groups of 7 is pushed back to A position, remain there throughout the piecean extra needle is brought into work on the ribber on either side of repeat ends. Machine settings: main bed set to slip <->, ribber set to normal knit
the ribber has now been set up for knitting every needle, every row, with the caston and desired edging completed. The first row is selected on the main bed for pattern knitting. since there are needles out of work and pattern knitting is involved, if KCI is used or end needle selection is not canceled, the end needles on the areas being slipped will be selected to the knitting position, so patterning errors will occur. The first row knit on both beds is shown on the remaining needlesBrother knits a row while preselecting for the next one. Here the needles in B would slip/ not knit on the next row, and needles out to D (Brother skipped the letter C in needle positions) will knit. Before knitting that next row, stitches on the now non-selected needles should be dropped across the bed this shows those stitches have been dropped, their needles are now empty, and returned to B position

end knitting with the same treatment as it bottom (swatch was simply dropped off).
It is possible with solid geometric shapes such as these to release stitches after each shape. The type of yarn used and loop behavior upon dropping stitches are variables that influence success in doing so (other swatches ).
An acrylic yarn was used: the first image is the fabric’s “relaxed view”.after steaming and pressing
the variation in width is due to adjustments in tension, the swatch folded over itself shows the difference in another way
