DEVICE ON A WARP KNITTING MACHINE FOR CROCHETING AN ELASTIC BAND WITH A COATING AND POSSIBLY FOR CROCHETING PICOTS, AND AN ELASTIC BAND PRODUCED WITH THIS DEVICE

摘要

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 centimetre 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). In front of the rubber-elastic threads there is a front single-weft cuttler (30v) to feed a front weft yarn (32v). A rear single-weft cuttler (30h) may be arranged behind the rubber-elastic threads. There are more than eight and especially twelve crocheting components per centimetre machine width to produce a particularly fine band. To produce a coating there is a weft-skein cuttler (50v, 50h) with sets of weft yarn eyed needles (52v, 52h) in front of and/or behind the rubber-elastic band (14).
