Divided stitch cam

Enclosing the Weft Yarn Earlier with DJ Fabrics

Problem case:

Enclosing the weft yarn by risen needles in advance.

Advantages:

Stitch cam can be exchanged easily.
The divided stitch cam can be configured separately for each system and for both carriage directions.
The converted knitting system with "divided stitch cam" can form stitches and tuck without restrictions.

Disadvantage:
Transferring and split stitches cannot be performed by this system.

Parts for Cam Conversion:

Application Examples :

Newly laid in weft yarns will, as they are not yet enclosed by fabric, not be hold below the needle crossing (crossing point of the supporting surface of opposite needles). Raising the needles earlier by the transferring curve allows to "lock" the weft yarn in the needle bed gap until the following stitch row is knitted.

System function
	Blue line: Shows the needle curve with DJ. The needle is already risen in front of the stitch cam. Holding deep is extended by the width of the stitch cam. Red line: Shows the needle curve with "Holding-deep by transfer function" and with the cam conversion designed for it.

Programming with M1plus:

Cam is equipped with divided stitch cam.

1: Define the Divided Stitch Cam option as cam conversion for each system (in front or/and at rear).

Present to the rear needle bed will automatically be disabled for this system.

2: Enter Stitch via split curve in front and rear into the System function control column.

3: Draw in weft and DJ within the same system.

4: Specify the cam function.

The stitch lengths are restricted with a divided stitch cam.
Only the way down from the channel to the loop sinking edge can be used.
Leading to the following gauge-dependent restriction:

Gauge	Maximum valid NP value
E10	11.8
E12	12.6
E14	13.0
E16	---
E18	---
E6.2	12.6
E7.2	13.0
E8.2	---

For each system at front / at rear and each direction the technical processing will check:

divided stitch cam present?
is the allowed NP value exceeded by specified stitch length?

In such cases the following message appears:
Exceeded maximum stitch length value (max. value) for the divided stitch cam.\n
