Dubied set-up: single bed cast on and welt

A tidy start: a row over the comb, then a few rows of tube that make a closed, stable edge. The comb hangs from the first row, so the first row has to wrap round its eyelets. On a single bed the rear needles knit.

Carriage settings on a Dubied

Single bed cast on (rear bed)
  1. rearfront1100
    Comb up between the beds from underneath, resting on the front bed. Tension loose, carriage on the right, pick up the carrier. Knit 1 row: the yarn goes round the comb's eyelets. Release the comb, knit 1 or 2 rows, then hang the weights.
Change to double bed: set-up and welt
  1. rearfront1111
    1. Front needles in working position. Knit 1 row.
  2. rearfront0110
    2. Knit at least 2 rows of tubular. Then set the cams for the fabric.
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. Select the needles.
  2. Bring the comb and wire up from underneath, as high as it goes, resting on the front bed so its eyelets sit against the rear jacks.
  3. Set the cams, tension loose, carriage on the right, pick up the carrier.
  4. Knit 1 row.
  5. Release the comb.
  6. Knit 1 or 2 rows, then hang the weights.
  7. For double bed, put the front needles in working position, knit 1 row on both beds, then at least 2 rows tubular.
  8. Set the cams for the fabric.

The full card

What it looks like
A tidy start: a row over the comb, then a few rows of tube that make a closed, stable edge.
How it behaves
Flat. The welt is a small double layer.
How it works
The comb hangs from the first row, so the first row has to wrap round its eyelets. On a single bed the rear needles knit. To go to two beds, one row on all needles joins them, and then tubular rows make the welt. The notes use the words set-up for the first row and welt for the tube. A rib with many needles out of action may need two set-ups, each followed by a rack. If the yarn cannot go back and forth between the beds, set up on all needles and transfer stitches away after the welt.
Machines
Dubied with set-up comb and wire.
Parameters
Tension loose for the set-up. Welt at least 2 rows of tubular. Weights after 1 or 2 rows.
Steps
1) Select the needles. 2) Bring the comb and wire up from underneath, as high as it goes, resting on the front bed so its eyelets sit against the rear jacks. 3) Set the cams, tension loose, carriage on the right, pick up the carrier. 4) Knit 1 row. 5) Release the comb. 6) Knit 1 or 2 rows, then hang the weights. 7) For double bed, put the front needles in working position, knit 1 row on both beds, then at least 2 rows tubular. 8) Set the cams for the fabric.
Charting
K/M 1 1 / 0 0 for single bed. K/M 1 1 / 1 1, then 0 1 / 1 0 for the welt.
Limits and common problems
Forgetting the front needles when you change to double bed. The comb can deform the bottom edge: to avoid that, set up after a separation (see dubied-separation).
