Dubied separation: draw thread and press off

Samples knitted one after another and then parted with a clean edge, with no comb marks. The comb can deform the bottom edge, so it is better to set up after a separation. It also saves starting each sample of the same width with the comb.

Carriage settings on a Dubied

Separation by draw thread
  1. rearfront0110
    Carriage on the right. Knit 2 rows in smooth strong yarn on the second carrier, then start the next sample: set-up, welt. Cut and pull the draw thread to separate.
Separation by press off
  1. rearfront0011
    1. Carriage on the right. Knit 3 rows.
  2. rearfront1111
    2. Knit 1 row. Cancel the yarn carrier.
  3. rearfront1100
    3. Pass slowly 2 rows with no yarn: the rear needles lose their stitches. Pick up the carrier with good yarn and start the next sample: set-up, welt.
Use this when the second carrier is not free. To separate, cut and pull out the slack row of 1×1 rib (step 2). Swap the beds in step 3 to drop the other bed's stitches.
How to read the cross
  • The four quarters are the carriage: top rear bed, bottom front bed, left moving left, right moving right.
  • Corners, knit/miss cam: 1 knits; ½ knits on high butts only and misses low butts; 0 is out of work.
  • Diamond, tucking cam: 0 no tuck; ½ low butts tuck, high butts knit; 1 all needles tuck. An empty diamond is all 0.
  • Numbers on the line are tension dials, 0 tightest to 20 loosest. A + means looser than your usual size.
  • Set-out: long tick high butt, short tick low butt, dot out of action.
Racking handle: up moves the rear bed left, down moves it right, up to 6 notches. Rack only with the carriage clear of the needles.

Steps

  1. Draw thread: set the cams, carriage on the right, knit 2 rows in smooth strong yarn, start the next sample. Cut and pull the thread to separate.
  2. Press off: knit 3 rows on one bed, knit 1 row on both, cancel the carrier, make 2 rows slowly with no yarn. Pick up the carrier and start the next sample. Cut and pull out the slack row.

The full card

What it looks like
Samples knitted one after another and then parted with a clean edge, with no comb marks.
How it behaves
Flat.
How it works
The comb can deform the bottom edge, so it is better to set up after a separation. It also saves starting each sample of the same width with the comb. A draw thread is a strong smooth yarn knitted between samples. Press off drops one bed's stitches with no yarn, then a slack rib row holds the two pieces together until you pull it out.
Machines
Dubied. The draw thread takes the second yarn carrier. If it is not free, use press off.
Parameters
Draw thread 2 rows. Press off 3 rows, 1 row, then 2 empty rows, slowly.
Steps
1) Draw thread: set the cams, carriage on the right, knit 2 rows in smooth strong yarn, start the next sample. Cut and pull the thread to separate. 2) Press off: knit 3 rows on one bed, knit 1 row on both, cancel the carrier, make 2 rows slowly with no yarn. Pick up the carrier and start the next sample. Cut and pull out the slack row.
Charting
K/M 0 1 / 1 0 for the draw thread. For press off 0 0 / 1 1, then 1 1 / 1 1, then 1 1 / 0 0.
Limits and common problems
The part between the comb and the draw thread, or between samples, can be waste yarn. Pull the empty rows slowly, so the needles do not snag.
Combines with
dubied-set-up-welt, dubied-cast-off.
Pieces and assembly
Several samples of one width in a row.
