  • Patent number: 4745781
    Abstract: The invention concerns an assembly of sets of tightly adjacent eye needles (12) for filling-yarn knitting machinery. One set each of eye needles (12) is anchored by injection-molding in supports (8,9) at mutually equidistant positions, the needles being mutually parallel by their main planes. Two supports (8,9) each with a set of eye needles (12) form one segment of eye needles. The heads (22) of the eye needles (12) of the first set (24) of needles alternatingly enter centrally between every two heads of the eye needles of the second set (25) of needles. The two sets of needles are fixed within the segments and are oblique in such a manner that a conceptual plane from one of the sets (24) of needles (plane (5) of the set) extending along the eye needles and through the heads of this set of needles intersects the plane (5') of the set of the other needle-set (25) in the region of the heads.

  • Patent number: 4313473
    Abstract: The belting has a single layer woven central portion (24) and two tubular edge portions (21, 22) and is made on a needle belt weaving loom provided with a knitting needle (37). The belting serves preferably for safety belts in motor vehicles. One tubular edge portion (22) is closed by a row of stitching (28') whereby the row of stitching does not lie at the outer edge of the tubular edge portion (22) but should disappear into the fabric at the edge of the central portion (24). By means of the invention the rate of production should be increased, which results from manufacture with two simultaneously moving weft thread insertion needles (30, 34) which simultaneously at each pick insert two weft threads (31, 35). To anchor one weft thread at the outer edges of the edge parts a common shed for both weft thread insertion needles is formed at least on the insertion side by the two outer edge warp threads (1a, 2a).

  • Patent number: 4174738
    Abstract: A belting with a single-layer central portion and two tubular edge portions is made on a needle ribbon weaving machine with one of the tubular edge portions woven as a single layer and then closed to form the tubular edge portion by exerting a pull on the weft thread; a knitting course maintains the tubular edge portion closed along its joint by means of a tuck thread and/or an interlocking thread which is buried in the fabric by feeding a greater length of tuck thread in the knitting course than usual or by laying in the interlocking thread into the head of the knitting needle from vertically above the knitting needle.
