Definitions

  • a set of parallel primary warp filaments are fed to a weaving location next to a set of parallel secondary filaments With a coupling element fed in between these two sets.
  • the primary filaments shed between the two outer levels of a three-level shed, the coupling element sheds between one of these outer levels and the central level of the shed, and the secondary filaments shed between the other outer level and the central level.
  • a pair of weft filaments are introduced as loops from the side of the shed corresponding to the secondary warp filaments, each waft filament being passed between a respective outer level of the warp and the central level.
  • the free ends of the loops are caught by a picker and either hooked together, or a binding filament is passed through them.
  • the one Weft thread has at its inserting side a bight overlying the coupling element.
  • the primary warp thread immediately adjacent the coupling element is of heavier weight than the other primary filaments as is woven oppositely to the coupling element.
  • the present invention relates to a slide-fastener stringer half. More particularly this invention relates to a stringer half having a woven in coupling element and a method of making such a stringer half.
  • a slide fastener is customarily formed of a pair of stringer halves each of which comrpises a support tape to whose longitudinal edge is secured a coupling element.
  • a slider can be slid along the two stringer halves to interleave the two coupling elements so as to close the fastener, and can be slid in the other direction so as to separate the two halves.
  • the coupling element is woven into the stringer half and a longitudinally extending flap is formed on the stringer half which customarily underlies this coupling element.
  • a longitudinally extending flap is formed on the stringer half which customarily underlies this coupling element.
  • the coupling element is insufficiently strongly secured to the tape.
  • An example of this is in a zipper-type boot or a suitcase having a slide fastener, since the fastener is frequently stressed considerably transversely to the longitudinal direction of the fastener. Thus it is a frequent occurrence in such articles for the slide fastener to be torn apart, with the coupling element being ripped free of its support tape.
  • Another object of this invention is to provide an improved method of making the slide-fastener stringer half.
  • a further object is to provide a slide-fastener stringer half having an integral coupling element, and a method of making this stringer half so that it overcomes the above-given disadvantages.
  • a slide-fastener stringer half formed of a plurality of parallel primary warp filaments which form a primary band and a plurality of secondary warp elements forming a secondary band extending longitudinally alongside the primary band and forming therewith an elongated strip.
  • a continuous synthetic-resin coupling element of the coil or meander type extends longitudinally along the strip between the bands.
  • a first weft filament is woven back and forth across the full width of the band between the warp filaments in cus tomary fashion.
  • a second weft filament is woven back and forth across the primary band only and has at that longitudinal edge of the primary band tuxzed toward the secondary band a plurality of bights which are looped around the coupling element.
  • This second weft filament and the first weft filament both have at the other longitudinal edge of the primary band a plurality of bights which are knitted together.
  • primary warp filament lying directly next to the coupling element is of larger diameter than the other primary warp filament and is woven into the support tape oppositely to the coupling element, so that when the stringer half is woven the thicker primary filament will always be to the opposite side of the shed as the coupling element.
  • the primary band is further formed with a longitudinally extending filament along its edge opposite to the edge under the coupling element, this filament being knitted through the bights of both the weft filaments along this edge.
  • the support tape has a conventional woven selvage at the edge adapted to be turned toward another such edge of another stringer half, and at its other edge has a knitted selvage.
  • this slide-fastener stringer half is made by feeding a plurality of primary warp filaments as a set next to a similar set comprised of a plurality of parallel secondary warp filaments to a weaving location, and feeding an elongated continuous coupling elements between these two sets to the location. Just upstream of the location these sets and the coupling element are periodically divided into a three-level shed.
  • the set of primary warp filaments is shed between the two outer levels of the shed, and the coupling element and the set of secondary warp filaments are each shed only between a respective outer level and the central level.
  • a pair of weft filaments is simultaneously inserted between respective outer levels and the central level. Thereafter the weave is beaten up in the conventional manner.
  • one of the weft filaments extends all the way across the shed when it is pulled tight and the other weft filament extends only as far as the coupling element, as described above.
  • Each weft is fed as a loop through its respective section of the shed, and a picker is provided at the far side of the shed to catch these ends and knit them together as the shed is changed and before the Weft is pulled tight.
  • the warp filament at the than the other primary warp, filamentsand is always shed across from the coupling element. In this manner this heavier thread or filament reinforces the tape and protects the weft filaments securing the coupling element to the tape.
  • the coupling element has a plurality of connecting bights which extend between separate teeth of this coupling element, and a filler cord extends longitudinally through thecoupling element.
  • the bights of the second weft filament, that filament securing the coupling element to the tape, are each looped around this filling thread and a respective connecting portion.
