Definitions

  • the invention relates to a method in the preamble of claim 1 specified type.
  • a zipper half consists of a Clasp link row and on the other hand from a band fabric, which together be connected via web technology.
  • the ribbon fabric is made of warp threads and out woven at least one weft, the weft in the form of Double shot loops is entered.
  • the row of fastener links is created due to a sinuous plastic monofilament, the link-forming turns Dome heads at one end and reverse turns at the other have. When weaving, the row of fastener links comes on a strip of fabric to lie.
  • connection between the fabric strip and the fastener link row provides a knitting thread, which is loop-shaped when weaving from this fabric strip lifted out and by gaps between the turns of the row of links through to the top of the row of fastener links, where his Loop heads are crocheted.
  • the crocheted mesh heads form one Stitch structure. While the strips of fabric are on the underside of the Closure link row is located, the mesh structure covers the top of the Row of fastener links.
  • the invention has for its object a reliable method in Develop the preamble of claim 1 specified type, in which the Product has a clean selvedge without a crochet edge, although one Ribbon fabric with double weft entries was woven. this will achieved by the measures specified in claim 1, which has the following special meaning.
  • warp threads under the row of fastener links in the finished product only in the level below the row of fastener links resulting strips of tissue run and not with each other are crocheted. These threads are referred to below as “additional warp threads" become.
  • the special feature of the invention is that the knitting thread at the same time the weft thread is in the fabric strip and when weaving in the form of double weft loops binds with the additional warp threads there. When tying with the The double-weft loops through the gaps become additional warp threads passed between the turns of the fastener link row and on the Top of the fastener link row, crocheted with its loop heads.
  • This Crochet of the double-shot loops partially cover the top of the Row of fastener links.
  • the double-shot entries of the knitting thread therefore create a clean, on the opposite edge of the fabric strip stitch-free selvedge.
  • the zipper half produced has a good appearance.
  • the crochet hook for connecting the double-shot loops from the weft-like Working knitting thread is the same crochet hook that covers the top cover of the row of fastener links.
  • the thread is entered by a weft needle and this weft needle not only creates the weave the additional warp threads in the fabric strip below the row of fastener links, but at the same time forms the gap between the turns of the Clasp link row passing through loops on the top to be crocheted together.
  • the weft needle Apart from the crochet hook, there is only one only tool required, namely the weft needle.
  • This weft needle is not just a weft insertion agent for the knitting thread in the fabric strip but also a loop head former of the knitting thread for the crochet hook.
  • the crocheting of the loop heads generated by the knitting thread can, as in claim 2 proposes to be done by an immediate mesh-like link. How Claim 3 indicates, but can also be done indirectly. For this you use at least one auxiliary thread that provides the stitch-like connection. How to results from claim 5, such an auxiliary thread in addition to the stitch formation between the loop heads of the knitting thread, also an independent one mesh-like connection between the row of fastener links on the one hand and the underlying fabric strip on the other hand. Through a Such a further auxiliary thread is the connection between the row of fastener links and the underlying fabric strip improved.
  • Such a lanyard serves e.g. for sewing fastening of the zipper half on a garment that to be equipped with a zipper.
  • the good looks of the zipper half according to the invention is characterized by that in claim 4 Measures promoted.
  • Such a carrier tape consists of carrier tape warp threads and a carrier tape shot, which in turn in the form of double shot loops in the Carrier tape warp threads is entered.
  • the carrier tape double shot is also generated Loop heads arranged in that zone in the method according to the invention where the loops of the one entered in the adjacent fabric strip Knitting thread through the gaps between the turns of the fastener link row pass.
  • the loops of the knitting thread therefore hold the loop heads of the Lanyard double shot firmly before being on top of the fastener link row, as already mentioned, knitted together like a stitch become.
  • a flawless result then also occurs on the free edge of the carrier tape Selvedge, because the tape double weft on this edge into that of the Enter the shed produced by the carrier tape warp threads.
  • the fabric of this product has then clean selvedges on both sides. That was previously, in the state of the art, with Double weft threads are not possible.
  • the knitting thread in such a zipper half with a carrying strap has a triple function.
  • the first Function is that the knitting thread is a weft builds up the fabric strip below the row of fastener links.
  • the second Function is that the knitting thread closes the row of fastener with the underlying fabric strips connects because it also weft in this strip of fabric is.
  • the third function of the knitting strip is that To connect the carrier tape to the fabric strip.
  • the row of fastener elements is regionally on its underside covered by the fabric strip already mentioned several times.
