Punch card book symbols and samples_ WIP

A number of variables need to be considered when adapting punchcard patterns for use on electronic knitting machines. These images pertain to Brother use, but the principles are shared between KM brands. I will add more information as time goes on. Online free downloads for magazines, manuals, etc. may be found at

some additions of late include designs in 12, 18, and 30 stitch repeats in addition to the familiar 24 and 40 ones, and to help with interpretations of symbols:  Japanese symbols for machine knitters 

 As the transition was made from manual machines, to pushbutton, and then to punchcard selection systems, the early collections included diagrams of  symbols familiar to hand knitters, and interestingly worded text that disappeared or was reduced in later punchcard books. I am presenting information in the order in which it appeared in this particular collection’s paper version, I have not found this volume in the above mentioned sources for free download. Images are gathered from more than the one source, so there is some repetition of information


LACE KNITTING

Punchcards may be used to guide one for hand techniques, here a version of e wrap is used on selected needles for weaving  effect, diagram on upper left is for a different fabric. Punchcard may also be used to help track twisted stitches , cables , and racking This is a 2 carriages patterning operation, so lace extension rails must be used, with each carriage disengaged from the belt while the other is moving across the knitting and back to its resting place. 

SYMBOLS IN PATTERN KNITTING

Below each punchcard, the repeat the is identified in numbers for stitches and rows. The cards presented are the minimum length required for the card to roll smoothly within the reader when joined for continuous knitting (at least 36 rows). Electronic knitters may isolate the individual, smallest repeat, draw only the squares that appear as white in the cards, enter them via mylar or download, and use color reverse.

Skip is aka slip or part. These cards would work for tuck stitch as well, may even tolerate elongation, depending on yarn thickness.

Opposite cam buttons are in use, the fabric changes appearance depending on which of the 2 stitch types is forward, so if instructions with cards are to be followed, then the starting side for pattern in this instance should be COR. Both tuck buttons (or slip) may be used as well, for a different fabric. If the tuck or slip texture is created over an even number of rows (2, 4), changing colors for each paired row sequences can create some interesting color patterns with very short floats akin to planned mosaics and mazes. 

The fair isle patters below are actually poor choices in terms of float control, pushing its limits. It is usually recommended that floats be no wider than 5 stitches, and even then, they may have to be controlled to make the finished garment easier to wear. 

Brother only produces a transfer lace (as opposed to studio simple lace, where the carriage transfers and knits with each pass of the carriage). The lace carriage is the one advancing the punchcard. The knit carriage does not select needles, but rather, knits 2 (or more) plain knit rows

Lace card markings, including for fine lace. In the latter, stitches are transferred and shared between pairs of needles, best knit in a light color, with smooth yarn so surface texture becomes more noticeable.

Lace point cams may be used on the punchcard machine to create vertical bands of lace. This is also achievable on the electronic by programming for knit stitches between vertical (or horizontal bands).

Tuck (left) and weaving (right) may be combined with lace. In these fabrics both carriages are selecting needles, so extension rails must be used. The two column on the left of the cards indicate movements for the lace carriage on left, and the knit carriage on right. Straight arrows indicate single carriage passes, curved ones 2.

Yet another fabric using 2 carriages selecting needles for patterning

Here the “openness” is created by having the appropriate needles out of work, creating ladders in those spaces. Some interesting results can be obtained by transferring the recommended out of work needles’ stitches to the ribber. “air knitting” can help with verifying proper needle placement is in use

to match location of out of work needles to markings for punchcards, which are often given with lines delineating 0 needle position, the image will need to be mirrored horizontally

Suitable for tuck and possibly tolerant of elongation as well:

Punchcard machines mirror motifs when knit. This may not be noticed when copying small repeats, but it becomes more evident in larger ones. For knitting on the 910, the supplied motif would need to be mirrored when programmed to retain the intended direction.

Here are 2 FI samples: the one on the left is fairly evenly distributed, so little if any difference is noticed, the one on the right sends the biker to a different forest

reversal of lettering


and when you think that that is all sorted out in your head, there are these in slip stitch, the direction of stitches matches, because the purl side is used, images reverse on the knit side 

the mirrored punchcards the punchcard change knob has selections for single motif and pattern knitting (KC)

the 910 has settings KC I and II, KC II cancels end needle selection, while in punchcard machines this has to be done manually if the pattern stitch requires it. One such example  is when any patterns are made with needles out of work. End needle selection would make the needles on each side of the empty space select forward and create a knit stitch. In tuck or slip, that would be an out of pattern knit stitch, in FI, a vertical line of the color in the B feeder would appear along on each side of the OOW needles.

Passap and Wincrea meet Mac OS adventures and then some

I recently finally set up my Passap, with the intent of creating some DBJ fabrics. As I have often described in previous posts, I now use GIMP for my image creating and editing. For my downloads to E6000 in the past I have used the Croucher cable with switch box and Wincrea running on an ancient Dell laptop with Windows XP installed. Files created on my Mac could be shared directly with the Dell via a network set up, or moved to and from it with a flash drive.

When I began to experiment after downloading the latest version of GIMP on my Mac I found .bmps  created using it elicited a wincrea floating point zero error message. If the images were then in turn opened in either MS Paint or GIMP 2.0 in the Dell and saved again, the error message and problem  in their being read by Wincrea in correct stitch and row counts went went away.

I now own a new Mac, and thanks to my son (who happens to live on the opposite coast) and his extensive IT help,  it has VMware Fusion  installed.  Consequently, I am now able to run Windows XP and associated programs on my Mac. My son also experimented with the problem .bmp files, and found the solution for eliminating the problem with the files created in the Mac OS to be in a simple check in a box in GIMP’s export options.

It follows the next attempt would be to try to download to the E6000 directly from the Mac.

A USB to serial cable is required for the connection to my download cable. The previously used Keyspan serial adapter was no longer usable with the iMac. It got replaced with a Sabrent. Windows drivers for the product may be downloaded from sabrent.com and are easily installed. With the wincrea setting to COM 3 I was then in turn able to download to my E6.

the proper setting the new adapteravailable com setting selections E6000

So I thought I was up and running, then I ran into a 213 error in the console when the switch box was in the download position. In an effort to isolate the problem I found a run away wire in the interior of the cable connection to the connection to the serial adapter.

I have always found Anne and Richard Croucher courteous and quick to respond to any email questions on their product. Richard was kind enough to review the photos below, and to suggest that soldering the green wire to the position indicated by the arrow might solve my cable problem. He also provided me with the accompanying  diagram. The cable is now awaiting for the skill, soldering supplies, and time of a friend.  “Just in case” a new switch and cable combination are now on order from the Crouchers. The adventure shall continue.

10/7/17: I have a new Croucher cable and switch box. I have not been able to successfully download again using VMware on the Mac, but I am successfully knitting again using the old Dell laptop for Wincrea downloads to the Passap . More experimentation to follow.

Lots of swatches

I have unearthed some of the hundreds of swatches that managed to  move with me when I downsized. They were produced when I used when teaching, often during class experiments and demonstrations. The yarn colors were chosen so I could spot them a mile away as my own (there were shared/public use yarn shelves in studio), and “different” enough so as not to tempt their being taken at any workshops ;-). I am adding them to my photostream as and when I can, and in turn shifting them into albums. In case anyone is interested the link is https://www.flickr.com/photos/drina2/ I am not certain I will have any opportunity to teach again, am hoping if people see them they may be inspired to try some of the techniques in materials and colors of their choosing. I would gladly explain more on any of them if any questions come up when viewing them.

Life changes; Flickr album links

There seem to be times when “life interferes with art” (or at least with one’s wished for schedule) is acutely true. I am in the throes of downsizing, moving and selling my home of 43 years, so there is not a whole lot of knitting or blogging going on.

I will be demonstrating at a Machine Knitting Guild on the West Coast next Saturday, and this had led me to re organizing my Flickr photo stream. For anyone interested, images of my samples albums links:  holding and ruching

Knitting failures: ribber

My previous post including information on brother ribber alignment suggested some things to test when ribbed fabrics are troublesome. I happen to own two 910 machines. The recent 2 posts on using generated mazes addressed developing the repeat for use in a punchcard model machine, but for the sake of speed I knit my samples on the electronic. In attempting to knit DBJ swatches relating the motif, I encountered random dropped stitches on the main bed, as may be seen in the last swatch pictured.

My Brother 850 ribber rarely gets used. I prefer to knit DBJ on my Passap, which can accept PC downloads.  With the 850 in place, all things I could think of were checked: ribber was balanced, at the correct height, brother ribber brackets and not studio ones in place by mistake, correct ribber sinker plate for model, all parts oiled, good condition needle retainer bar on main bed, no needles that vaguely look like they need to be replaced, familiar yarn in use. Knitting fabric single bed with ribber engaged and weights gives expected results with no problems, while dbj, no matter the setting, begins to drop stitches randomly or in groups on main bed (tried different amounts of weight as well). I did not try to use a fine knit bar, since the yarn in use had not required it in the past.  After spending way too much time rechecking everything yet again, I moved the knitting close to color changer, away from the center of the machine, and the darn thing knit perfectly. Back to center, same problem as before. I cannot see any noticeable difference in spacing between beds or gate pegs in the center, assume there may be an issue with some bowing, and briefly I got things to knit properly by lifting the middle of the bed up a bit with a support. A second shot at it with support failed. I even changed needles in the middle of the main bed. A few instances of mis patterning were probably due to static, relieved by using a vaporizer in the knitting room for a while. I took the ribber out of sheer stubbornness, removed it, slapped it on my second 910, using the same needle retainer bar on the main bed, and knit the same pattern with only one dropped stitch and one mis patterning error, knitting as fast as possible. I am admittedly flummoxed. The only thing I did not try was to use the troublesome 910 on a different knitting table. Some days are meant for walks on the beach and eating chocolate instead of knitting ;-).

 

Carpet or pile stitch knitting on Passap and Brother KMs 2

Trial swatches do not necessarily require a permanent edge. A main bed cast on with all open stitches is familiar to knitters accustomed to using a single bed Brother cast on comb. A quick version of the same type of cast on is also doable when both beds are in use, and the goal is to knit all stitches only on one bed or the other. The broken toe cast on for rib is so called because if comb and weights are hung in the wrong location on the needle bed, when stitches on the opposite bed are dropped, so will the comb be along with weights, heading for your feet. If the ribber is going to be the bed doing the knitting that anchors dropped stitches or pile in Brother kms, please note: prongs of ribber comb line up directly in front of main bed needles (blue arrow) and to each side of the loops on ribber bed needles (red arrow). The ribber comb wires will anchor down loops on needle bed where plain knit rows will be formed. As mentioned above, this method will result in stitches all being open, does not produce a permanent edge, is suitable for quick swatching or for waste yarn at the bottom of weighted fabric. It is possible to perform this cast on with ribber comb with wire already inserted in both brands, but the broken toe method is potentially less hazardous to needle health.brokent_toe_arrowsAnalyzing what is required to move between km brands with the goal of achieving 2 color or isolated pile motifs: in Passap with the back bed set to FX, one arrow key, EON pusher/ needle selection changes every 2 rows. In Brother this may be achieved on the main bed by pushing in one tuck button and programming a repeat.  The alternate, adjacent cam button, left in its normal position, will knit every stitch when knitting direction is reversed regardless of whether any needle selection is happening. On the ribber lili buttons may be used for alternate needle selection. Its levers determine whether tucking or slipping, in one direction or both, occur. The number of stitches on the ribber must be even. An easy visual check is to check markings on needle tape, which consist of what I refer to as dashes and blanks. For an even number begin with one, end with the other.  Passap will automatically revert to the alternate pusher for patterning on the subsequent 2 rows. In using lilis this is not an automatic function, and some handwork is required to obtain the same effect by changing first needle selection every third row as seen in this post.

If the ribber is chosen as the loop making bed, selection there needs to be manual for any pattern other than across whole rows. In my swatch, to knit across all needles the ribber carriage is set to slip in one direction, knit in the other. The all knit rows in pile knitting need to follow the ones with tuck loops on the opposite bed.  Extra needles are on main bed, which creates the fabric backing. The ribber carriage can be disengaged and used to drop stitches after all knit row on the main bed.

In the actual knitting, if plain one color pile with plain color backing is the goal, some rules may be broken. The thickest, most stable pile is achieved when the yarn anchoring the loops is as dense as possible. If the goal is to knit every stitch across each row to create loops and in turn drop them, one is in fact working an every needle rib. This makes it possible to create tuck loops on either bed creating the backing across the whole row, because in fact there are stitches on each side of the tuck loop on the opposing bed anchoring it in place. Normally when 2 or more needles tuck side by side, rather than the stitch formation usually seen in tuck, the loops do not get anchored, drop off, and create a float like those seen in slip stitch patterns.

In my first sample, the fabric is cast on the main bed, the loops are formed on the ribber. The carriages are set for main bed to tuck traveling to right, knitting to left. The ribber is set to slip to left, knit to right. The ribber is used to drop the stitches, simply by disengaging it from the main bed, and running it across from one side to the other. Dropping stitches occurs (on either bed) after all stitches have been slipped there for one row (no needle selection if patterning). Starting side for my swatches was on the left of the machine. It is helpful to have a ruler or tool to help push loops down between the beds after dropping each row of loops, and also to occasionally drop the ribber in order to check whether any loops may be caught on gate pegs.

In this swatch I had some problems (blue arrow) on the right side related to changes in tension while determining what might be the best. Section 1 has every needle tucking on the main bed. Section (2) begins to try to emulate the Passap pusher selection using an EON 2 row tuck repeat on the main bed, resulting in things going awol and loose, even at tightest tension possible on the main bed. Any time patterning is used on the main bed, end needle selection is cancelled (KCII). The tuck repeat2 row tuck

ribber loops2To create every needle loops for pile on the main bed: CO is on ribber. With settings on image below left (no lili buttons in use), the ribber tucks loops on every needle traveling to right, knit all stitches moving to left. Moving to the right the main bed knits on every needle, slips whole row moving to left, giving the opportunity to drop stitches off. With settings on below right, lili buttons are in use, and the ribber now produces an EON needle selection, every row. Left alone the selection is what would be seen using the 1X1 card on the main bed, its repeat 1X1tuckloops on MBThe yellow yarn is a 2/8 good quality wool knit at 4.2 on main bed, 3.2 on ribber. Switching to a rayon twist of similar thickness created instant havoc. The dark grey was a mill end, tighter twist 2/8 wool. Red arrows show what happens when loops are caught up on gate pegs and not immediately noticed. The green arrow indicates longer loops that can happen when knit stitch on either side on the opposite bed do not knit off properly. The result is a dense wool fabric, so the tendency to roll at top and bottom of each piece toward the “knit” side of the fabric needs to be considered at top and bottom edges of finished pieces.

In 2 color knitting, or creating isolated motifs whether on one color or striped ground, anchoring loops by tucking on every needle is no longer possible, making reverting to EON needle selection on ribber a necessity. The results are dramatically different. These swatches were made using lili buttons or hand selection on ribber, loops on main bed. If things don’t work in one color, they will not in 2, so one color, every needle pile is a place to start evaluating the results

1X1 lili selection left me with “where are the loops?”white_lili

In bottom section here I tried 1X1 hand selection for 2 consecutive rows,  the narrow band in center back was back to 1X1 to separate areas using lilis, at the top I used lili buttons and brought an extra needle into work on ribber before traveling to right every third row (making needles in work on ribber an odd number), returning it to out of work before knitting back to right. Dropping stitches every 4 rows makes tracking the sequence easier. The resulting pile is far more “subtle” than samples worked with every needle tucking on the bed creating the backingyelllow-lili_500

So far I still have had no luck with getting anything that does not look like a variant of drop stitch lace when attempting patterns separated for 2 color knitting, either in embossed one color, or in striped 2 color versions.

Zig Zag ladder lace 2: hand knit

I work primarily on a Mac, Maverick OS. Intwined software has had some issues operating in Mac consistently in the latest OS versions. The chart to text can be a really nice feature. The repeat, drawn here with symbols in the built in stitch library, shows errors in row 2 and 4 of the accompanying text.single repeatmistakes single

On a larger canvas, the original repeat is outlined below in red. Yellow indicates knit border stitches around ladder lace pattern repeats; row 22 is absent from the text that accompanied the larger chart.

Taking the information above, here I added numbers that reflect actual repeat rows, used the arrows as a reminder of change in direction of zig zag, and the red outlines vs green indicate changes in type of knit decrease. It is easy to add as much or as little additional information as one feels helpful. There are controls for line thickness, shadows, etc.

JKnit is another program that may be of interest to anyone who prefers to track their projects, progress, and much more on their iPad or iPhone. The Lite version is free for both devices.

Below is an image of the hand knit swatch, unblocked, which appears three dimensional; transfer  lace has traditionally been blocked to lie flat and maximize eyelets. The fabric may be very interesting without blocking. If a slightly thicker yarn with “memory” is used, the piece may be steamed lightly, and the pattern segments will tend to shift in and out from the flat surface, whether the piece is hand or machine knit.IMG_1901

The yarn used was a “throw away” swatch testing acrylic. A very quick, light press and a bit of steam and here it is in the resulting killed, forever flattened version

Website changes

I may be changing web host and am experimenting with themes in my recently updated version of WordPress. This particular one renders content more easily viewable in portable devices, where sidebars are now available by toggling screens. Please excuse any inconvenience while issues are being sorted out, look for more frequent posts and changes in the new year.

Low tech moment/ memories

My 910 electronic of late has had some erratic patterning I cannot explain, and today the laptop (replaced an older dell) containing all my Passap design files  and knitting software may have bit the dust (I used bit knitter back in amiga days, and  later a cable from England  and PC for downloading, so this is like entering a time machine). As a result, for the first time in a couple of decades I am back to using something that would almost qualify for a “does anyone know what this is?” post

It’s back to the drawing board, literally, and to getting card, sleeves and ink to get read properly by the KM. One thing that is helpful with the long lines especially, and staying within them, is black drafting tape from stationers that sell architectural supplies (kept that). White correction tape can cover up any mistakes (since markings need to be in ultra black ink), and I may have ditched all I had thinking I might never again actually have any use for it. Happiness is…

follow up 9/10: The original error message on black screen was “non system disk or disk error, replace and press any key when ready”. I had recently transferred some ancient files from floppies onto my hard drive via a floppy drive, and somehow it appears the system wanted to boot from that, even though it is had not been connected  since the download (there was nothing in the disk drive). Via an online search I found information on BIOS, changing boot sequences, and learned what some of the F keys do on a PC.

http://www.auslogics.com/en/turbo-windows/change-BIOS-set… was a site I found helpful.

That said, wincrea took its turn, gave me an error message I had no idea even existed in loading 2 out of 6 new patterns, so my puzzles are are multiplying. Online communities are great for getting help, especially for those of us that don’t have technical backup easily available. Hard to imagine life if the power goes out! BTW: yes, I have a punchcard machine for a spare, just in case….
