Chains
As chains are called:
- the correct connection of two knitted fabric edges to achieve an elastic, non-bulky seam
- the edging of fabric edges ( overcasting ) with one stitch more or less perpendicular to the fabric edge.
Examples are shirt collars, stockings (closure of the toe), carpets and the like. The linking machine and chain stitch machine are used mechanically.
While each stitch of the end row has to be knocked onto the needle bed correctly when linking stocking tips in order to create a real linking seam, one speaks of "blind linking" if this is not done correctly. Since it takes a high level of concentration and perseverance to create a real warp seam, this seam is rarely found.
A simpler alternative is the Rosso seam , in which the goods are sewn together when folded twice. The Kettel seam should not be confused with the chain stitch in embroidery .
A weaving or carpet weaving workshop specializes in particular areas of processing floor coverings. There the edges of the carpet are covered by special linking machines with textile yarn, fabric edges or leather. In addition, each edge is protected with a color-coordinated textile lower belt. This creates professional and clean edges. Fraying of these cut edges is prevented. The fastening of the carpet edges with chain yarn is also referred to as carpet binding or binding off.
