Dubied basics › Starting and finishing

Dubied double bed cast off

A chained top edge with no live loops, like a crochet chain along the last row. Everything goes to one bed, then one row on both beds makes open loops between the beds. A latch tool pulls each loop through the one before, so the edge cannot run.

Carriage settings on a Dubied

Double bed cast off
  1. 1. Transfer all the stitches to the rear bed. Loosen the tension on both beds.
  2. rearfront1111
    2. Carriage on the right, all front needles in working position. Knit 1 row: the empty front needles pick up stitches.
  3. 3. Carriage on the left. Lower the front bed to show the open loops. With a latch tool take the first stitch on the right, then pull each next loop through the one on the hook. Break the yarn, pull it through the last loop, take the work off, close the beds.
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. Transfer all the stitches to the rear bed.
  2. Loosen the tension on both beds.
  3. Carriage on the right, front needles in working position: knit 1 row, the empty front needles pick up stitches.
  4. Carriage on the left, lower the front bed to show the open loops.
  5. With the latch tool take the first stitch on the right.
  6. Keep it on the hook, take the next loop and pull it through.
  7. Go on to the end.
  8. Break the yarn, pull it through the last loop, take the work off, close the beds.

The full card

What it looks like
A chained top edge with no live loops, like a crochet chain along the last row.
How it behaves
Flat.
How it works
Everything goes to one bed, then one row on both beds makes open loops between the beds. A latch tool pulls each loop through the one before, so the edge cannot run.
Machines
Dubied, latch tool.
Parameters
Tension looser on both beds than for the fabric.
Steps
1) Transfer all the stitches to the rear bed. 2) Loosen the tension on both beds. 3) Carriage on the right, front needles in working position: knit 1 row, the empty front needles pick up stitches. 4) Carriage on the left, lower the front bed to show the open loops. 5) With the latch tool take the first stitch on the right. 6) Keep it on the hook, take the next loop and pull it through. 7) Go on to the end. 8) Break the yarn, pull it through the last loop, take the work off, close the beds.
Charting
Worked by hand: note it as the last step of the sample.
Limits and common problems
Tension too tight makes a tight, puckered edge [inference].
Combines with
dubied-separation, machine-linking.
Pieces and assembly
Top edges that show. For samples, a separation is quicker.
