  • Patent number: 4210180
    Abstract: A slide fastener stringer is disclosed, while has a woven tape carrying a row of coupling loops which is likewise woven, instead of being stitched, into an edge of the tape. The row of loops is secured by a plurality of binding warp threads extending longitudinally of the tape and overlying the upper portion of each of successively interconnected loops. A binding weft thread, separate from the tape foundations weft, is interlaced with the binding warp threads in a plane defined commonly by the successive upper portions of the loops and interwoven with the foundation weft thread interiorly of a heel portion of the loop, thereby securing the loops firmly to the tape without any such thread behind the heel of the loop which would otherwise interfere with the movement of a slider.

  • Patent number: 4181159
    Abstract: A slide-fastener stringer is formed by weaving a weft in a warp and simultaneously forming a continuous coupling element along each of the confronting edges of a pair of tapes simultaneously produced by the weaving operation. The synthetic-resin monofilament forming the coupling element is passed around a mandrel between the warp stretches so that the heads of the two coupling elements are produced in interdigitated form. The ground weft yarn is carried from the coupling element side of each set of warps through the shed to the opposite edge of the tape where it is locked into other loops of previous passes of weft by knitting.

  • Patent number: 4174736
    Abstract: An apparatus for manufacturing a woven slide fastener comprises means for weaving a slide fastener stringer tape, a mandrel around which a monofilament is coiled as it is woven into the stringer tape, and a coiling rotor assembly having a pair of wheels rotatably mounted in a pair of housings and on a floating axle to which the mandrel is fixed, and having guide means rotatable for revolving the monofilament in an orbital path around the axle. A pair of plungers jointly or individually act between the floating axle and one of the housings along a path diametrically across said orbital path by which the axle is held immovably with respect to said one of the housings. The plungers are retractable one at a time out of the orbital path so as to allow the monofilament and the guide means to cross the path of movement of the plungers.
