  • Patent number: 5642633
    Abstract: The invention pertains to an elastic band, in particular for upholstery on the backrests of chairs, etc. The band has rubber threads (2, 2a, 2b) running in its longitudinal direction. On both sides of the rubber threads, running transverse to them, are from and back woof threads (4, 6) made of inelastic textile material. The band is designed for crochet production. It has weave threads made of inelastic material, with each rubber thread (2, 2a, 2b) having two weave threads (7, 8) one of which, as stationary weave thread (7), always loops around the same rubber thread as well as the front and back woof threads (4, 6). The other, the jump weave thread (8) makes loops around a first rubber thread (2a) and around a small, odd number of successive from and back woof threads (4, 6). It then jumps to a neighboring second rubber thread (2) and with it makes an equal number of successive front and back woof-thread loops. It then jumps back to the first rubber thread (2a), etc.
