Abstract

A device on a warp knitting machine for crocheting an elastic band with a coating and an elastic band made with this device. The band may also have picots at its edges, that is small loops. The device is intended to facilitate the production of very fine bands with a distribution of more than eight and especially twelve needles per centimeter of machine width and even more if possible. The coating should be patternable. The coating may be produced on only one or on both sides of the strip. The device has crochet hooks (4), a cuttler (80) to feed skeins of rubber-elastic threads (14) and a cuttler (20) to feed skeins of warp threads (22).
