Control of Knitting Systems and of Holding-down Jacks
The knitting system:
Each knitting system can knit using the three-way technique without limitation.
Single needle selection in 5 positions:
- Stitch
- Tuck
- Out of operation
- Delivery / Split - Delivery
- Receiving / Split - Receiving
Possibilities of stitch formation:
- Stitch
- Tuck
- Out of operation
- Transfer from the front to the rear needle bed or vice versa
- Transfer simultaneously in both directions
The selection system only selects the needles which knit a stitch or tuck, transfer or split-stitch.
All other needles are not selected and do not sink the stitches.

II. Holding-down function:
The holding-down jacks hold down the fabric when the needles for stitch formation are driven out. The holding down jacks are moved by the holding-down jack control unit on the carriage.

| Meaning |
|---|---|
1 | Holding-down jack control unit |
2 | Swiveling brush holder |
3 | Jack slider |
4 | Leading jack slider |
5 | Following jack slider |
The leading jack slider (4) is switched upward.
This pivots the holding-down jacks downward into the holding-down position during needle raising and these hold down the stitches.
The following jack slider (5) is pulled back and the holding-down jacks swivel back again. The holding-down jacks are open during yarn insertion.
When the carriage reverses, the jack sliders are switched over automatically.
