Definitions

  • ABSTRACT A slide-fastener stringer comprises a pair of warp-knit tapes having confronting edges carrying respective coupling elements.
  • Each tape consists of a knit foundation formed by a plurality of transversely offset longitudinally' extending warp chains joinedtogether transversely by a plurality of laid-in weft filaments.
  • the guide bars for the warp chains can move in a 0- ll l-O or 2-0/0-2 pattern, or a pair of warp chains with these patterns can be knit.
  • the guide bars for the weft filaments move in a 4-4/0-0 pattern, laying these filaments into each course.
  • the knit is thermofixed and formed with holes along the edges for accommodating the stitching securing the coupling elements. l-leavy crimped or textured bulk yarn is used as weft filament.
  • the present invention relates to a slide-fastener stringer for a slide fastener having a coil-type coupling element.
  • Such a stringer usually is formed by a pair of woven tapes carrying on their confronting edges the coupling coils; the latter are usually made of a monofilament tape to another or from one portion of the same tape to OBJECT OF THE INVENTION It is, therefore, an object of the present invention to provide an improved slide-fastener stringer.
  • Another object of this invention is to provide a stringer of the character described which is less expensive to manufacture than the conventional strings described. Yet anotherobject is the provision of astrin'g er tape 'to'whi'ch a coupling element can be attached with no detrimental effects.
  • a slide-fastener stringer constituted by a pair of warp-knit support tapes each formed by a plurality of transversely offset longitudinally extending warp chains (wales) and'laid-in weft threads interconnecting the chainsto form a warpknit foundation.
  • a warp-knit tape is highly advantageous to the system of the present invention. It is a rigid relatively nonelastic knit, clearly distinct from the elastic weft knits. Furthermore, it is cheap and easy to produce in the form of a narrow tape.
  • the guide bars for the warp chains move in a O-l/l-O or 2- 0/O-2 pattern, or two warp chains with thesepatterns can be provided in the foundation.
  • the weft filament advantageously a bulk, heavy crimped or textured yarn, is laid in with a 0-0/4-4 pattern.
  • the tapes are thermofixed for added rigidity, thereby thermally fusing the threads of the knit loops and the weft together and, if desired, to the coupling element.
  • FIG. 1 is a detail view of a slide-fastener stringer according to a first embodiment of the present invention
  • FIG. 2 shows the combined notation for a second embodiment of the invention
  • FIG. 3A shows the notation for the guide bars I knitting the tapes of FIG. 2;
  • FIG. 3B shows the threading of the needles for the tapes of FIG. 2.
  • FIG. 2 represents standard tricot point paper notation wherein each dot represents a needle.
  • the vertical rows of dots symbolize the wales and the horizontal rows symbolize the courses.
  • the lines passing around the dots represent the paths of the guides during knitting and, therefore, the pattern of the yarns carried by these guides.
  • FIGQ3A shows the paths of the individual guides, and FIG. 3B shows which of the guides are threaded for each row of needles.
  • the guide bar can move from one space to another during each knitting cycle, i.e., the formation of each course, and then move back during the next raising and lowering of the needles.
  • the figure notation for a guide which moves from space 0 to space 1 during one knitting cycle then back from space I to space 0 during the next cycle is O-l/l-O, with the slash mark (I) separating the two cycles.
  • the notation 5-6/6-5 or 13-14/14-13 would represent the same guide movement further along on the guide bar.
  • the other type of guide movement of interest here is that of laying-in.
  • the guides do not move in frontof the needles (overlay) but merelyshop back and forth behind the needle hooks between cycles.
  • the notation here is similar, so that 4-4/0-0 is the figure notation for a guide which, as the needles move up and down for one course, stands in space 4, and then moves to space 0 where it remains as the next course is knit.
  • the first two digits signify thetwo positions between which the guide reciprocates during one knitting cycle and the second two digits indicate the end positions for the next cycle. Since for laying-in the guides do not move during the knitting cycles, but between them, these numbers remain the same-to each side of the slash mark.
  • FIG. 1 A pair of slide-fastener support tapes 1 produced on the same Raschel knitting machine are shown in FIG. 1.
  • Each tape 1 carries a coupling coil 3 secured by stitching 2.
  • a filler cord 10 passing longitudinally through each coil 3 is pierced by the stitching to hold the coils 3 in place on the confronting tape edges.
  • the coils may optionally be lodged in loops or openings formed in the tape.
  • Each tape 1 is further formed by warp filaments 4 (solid lines) defining warp chains or wales 8 separated by troughs or grooves 9 and by weft filaments 5 (dashed lines) underlapping the filaments 4.
  • the warp filaments are chained in a O-l l-O pattern, Whereas the weft filaments 5 are simply laid in with a 4-4/0-0 pattern.
  • the confronting edges of the tapes 1 are joined by a connecting yarn 7 (dot-dash line) which is also laid into the knit, but with a 2-2/0-0 pattern.
  • FIGS. 3A, and 38 we show the operation of four guide bars used to make a modified knit illustrated in FIG. 2, with the two front guide bars knitting in opposed sensesand both back guide bars laying in. More specifically, the first guide bar lays in the yarn 5 with the above-mentioned 4-4 /0-0 pattern.
  • This guide bar is not fully set but only has eighteen of its 24 guides threaded, with the lOth, 11th, and 12th, and 22nd,,
  • the second guide bar only carries two threads 7, in its 12th and, for reasons set forth below, 24th guides, which it lays in with a 2- 2/0-0 pattern.
  • the third guide bar knits a thread 6 in a 2-0/0-2 pattern forming open laps and has its twelfth and 24th guides empty.
  • the fourth guide bar is fully set and forms open laps with the yarn 4'in the above-given -1/1 -0 pattern.
  • a four-guide-bar machine knitting as described immediately above produces two warp-knit bands which are extremely rigid and nonelastic. These two bands or tapes are longitudinally interconnected by a single thread which, upon removal, after. attachment of the coils 3, leaves two selvedged tapes, since none of the guides'except for the two of guide bar 2 are threaded where their yarns would bridge the gap between the 12th and 13th wale,"or would extend beyond the 24th wale.
  • the 24th guide of the second guide bar is threaded. Such is the case when more than two tapes 1 are knitted simultaneously. Indeed,it is advantageous to produce four-or more tapessimultaneously, which can be subsequently subdivided into pairs if desired.-
  • the laid-in yarns 5 are relatively voluminous; they-can be synthetic-resin mu'ltifilament yarns or, if such yarns are not voluminous (bulky) enough, textured synthetic resin multifilament ormonofilament yarns which have been passed through a crimping machine.
  • the knit producedthereby is closed but light, and theeveritual stitching of the tapes to a garment will not cause it to buckle.
  • the stitching 2 for the coupling elements 3 advantageously passes through the holes 11 to prevent this stitching 2 from bucklin the tapes 1.
  • the tapes 1 are further s abilized by a thermofixmg process. They are heated after formation to a temperature sufficient to slightly soften the yarns and give them a set or fuse contacting portions together and/or to the nylon or polyester coupling element.
  • a slide-fastener stringer comprising:
  • each tape constituted of a plu'rality of transversely offset longitudinally extending warp chains of warp loops and laid-in weft filaments transversely connecting said chains and traversing said loops to form a warp-knit foundation; and respective elongated continuous coupling elements interconnectable upon movement of a slider therealong and lying along said edges while being stitched thereto by stitch loops passing around turns of the coupling elements and through said support tapes between warp chains thereof.
