Weave-in Device
The weft yarn presser foot (1) supports the inlay of the weft yarn:
- The weave-in device holds the weft yarn deep so that it does not obstruct the knitting process.
- The weave-in device holds the weft yarn deep enough so that it is enclosed safely in the following system.
- In working position the weave-in device is between the front and the rear needle bed, beneath the needles.

What is a weft yarn like?
An weft yarn is inserted toward the stitch rows but not knitted.
The insertion of the weft yarn is carried out by the weft yarn carrier. This yarn carrier runs thus so far ahead before the knitting system that the yarn is only inserted but does not knit any stitch or tuck.
The weave-in device presses the thread downwards between the needle beds.
The weft yarn is enclosed in the following system, it is tied in the fabric with stitches or with transfers.

You can use the weft yarn technique with the following machines:

Normal yarn carrier |
CMS W |
Normal yarn carrier |

What is a weft yarn used for?
- For reducing fabric extensibility:
Use weft yarn with lower elasticity. - For improving elasticity:
Use weft yarn with a higher elasticity (rubber). - To achieve pattern effects:
For example fillings in tubular rows
