Working with the weave-in device

Height of the weave-in device

• The weave-in device is to guide the weft yarn (touch slightly), but not press too hard, so that the weft yarn does not get damaged or elongated.

The adjustment height depends on:

• Quality of the weft yarn (friction coefficient, elasticity, twisting, moisture, hairiness, tensile strength)
• Yarn gauge of the weft yarn, yarn count / twisted yarn
• Yarn tension, yarn feeding

If the weave-in device is adjusted too high, the weft yarn is partially above the stitches of the basic yarn.

Remedy: Step by step, adjust the weave-in device deeper.

Yarn tension of the weft yarn

• In case of a very elastic weft yarn, we recommend using a feed wheel.
• If a yarn loop results when changing the direction of the weft yarn carrier, a higher restoring force is necessary.
• Increase the restoring force at the yarn control device
• Gauge range E10-E18:
  Assemble a yarn control unit of the coarser gauge range (E5-E8):
  ADF: ID 4170 270 467
  CMS: ID 4170 237 124

Carriage Speed

Start with a lower carriage speed (e.g. 0.7 m/sec) and increase it step by step.

Yarn carrier staggering optimized by rows (YDopt)

Recommendation:
Work with YDopt, so that the Weave-in device - Yarn carrier distance is automatically taken into account.

Working without YDopt

• YDF=2
• Assign the yarn carriers so that the weft yarn carriers are placed on the inner tracks. Thus, shorter run time can be achieved.
  Inner Tracks:
  CMS-W = track 4 + 5
  ADF 16-W = track 4 + 5
  ADF 24-W = track 6 + 7
  ADF 32-W = track 7, 8, 9 +10
• With the yarn carrier staggering YD ensure that there is sufficient space for switching on and off the weave-in device.
• Yarn carrier staggering if the weave-in device is active:
