Definitions

  • ABSTRACT A method and apparatus for weaving a row of slidefastener links into the edge of a tape which is formed on a needle loom which feeds the links in the direction of the warp while simultaneously weaving the tape from warp and weft threads. At least one pair of warp threads tie an edge of the links into the edge of the tape, while the weft threads form loops which engage the links from the outside and run in an opposite direction over and under the row of links. Guiding means aid in tying off the warp threads and weft thread loops which pull in opposition to each other near the reed stop of the loom.
  • Applicant acknowledges his prior West German Pat. application No. P 23 28677.3 filed in West Germany on June 6, 1973 in the name of the Assignee Suplex AG, Wylenstrasse 6, 6440 Brunnen, Switzerland and claims the priority of said West German patent application under the provisions of 35 USC 119.
  • the invention relates to a method and apparatus for weaving a row of slide-fastener links into the edge of a tape, using a needle loom, the said row of links being fed in the warp direction, while the weft is introduced laterally of the row of links.
  • this purpose is accomplished in that the row of links is secured with at least one pair of tie-in warp threads which are drawn into the edge of the tape by the weft entry, with the formation of loops engaging from the outside and running in opposite directions over and under the row of links, and are then tied off.
  • a further development of the method of the present invention provides for the tie-in warp threads, at the side of the row of links remote from the tape, to be guided, by means of a guide device which is arranged approximately on a level with the reed-stop location, substantially in the warp direction, and from there guides the threads inwardly towards the edge of the tape; and the guide device serves for the base-side defleeting curves of the weft-thread loops which are inserted into the tape of the needles to be tied off at the tie-in warp threads so that the said tie-in warp threads, operate in opposition to the weft-thread loops returning at least once between consecutive entries of the weft-thread loops and crossing the row of links.
  • the row of slide-fastener links is secured to the tape by means of pairs of opposing loops of the weft threads and tie-in warp threads, which loop repeatedly around each other directly at the weaving-edge of the slidefastener links and provide a specially reinforced tape edge especially adapted to position the row of links accurately and securely.
  • the row of links is fed inside a guide bar opening approximately on a level with the reed stop, the tie-in warp threads being deflected at the end-face of the said guide bar.
  • the two tie-in warp threads are fed to the end-face of the guide bar and form an acute angle therewith, as seen in the direction of the weaving plane.
  • the method according to the invention may actually be carried out by using only one weft thread. It is desirable, however, to operate with two weft threads, one of which is passed into the shed above the row of links, while the other is passed into the shed below the row of links, and both being looped around the warp tie-in threads. If two weft threads, i.e., two needles, are used, there is no need to change the direction of the needles. Moreover, since in the method according to the invention, the row of links takes no part in the shed-forming movements, the method according to the invention may be carried out on a relatively simple needle loom operating at high speed. According to still another characteristic of the invention, the feed of the row of links is controlled in such a manner that, at the moment of the reed stop, a gap in the row of links is open in the direction of deflection.
  • each tie-in warp thread is always looped with a curve around the same side of the teeth of the row of links, and is tied off between the said teeth by the weft thread operating on the other main side of the tape.
  • the invention provides, for the execution of this method, a needle loom having two parallel needles operating in the same direction, and a guide bar for the row of links extending in the direction of the warp and opening approximately into the area of the reed-stop location, the operative position of one of the needle being above, and that of the other needle being below, the said guide bar, the said guide bar being arranged as a cover for the row of links against the tie-in warp threads, and the end-face thereof being the deflecting device for the tie-in Warp threads.
  • FIG. 1 is a simplified representation of the most important parts of the loom for the execution of the method according to the invention, as seen from the end where the weave is produced;
  • FIG. 2 is a simplified side elevation of the loom
  • FIG. 3 is a plan view of the loom in FIG. 1;
  • FIG. 4 is a diagrammatic representation of theplan view of a slide-fastener strip being produced, showing the feed of the two tie-in warp threads, the two weft threads, and the mouth of the guide bar for the 'two of links;
  • FIG. 5 is a view in perspective of the looping knots formed after new weft-threadloops have been placed in the fabric
  • FIG. 6 shows the intermediate stage according to FIG. 5 but in a view similar to that in FIG. 4;
  • FIG. 7 is a plan view of the slide-fastener tape, in which the rows of links are woven to the edge of the tape in a different way;
  • FIG. 8 is a view of the tape from the right-hand side of FIG. 7.
  • FIGS. 1 to 3 show warp or ground warp threads 1 of the tape in the open-shed position, a guide bar 2 approximately U-shaped and arranged at one edge of the tape, a helical row of links 3 running in the said guide bar in the direction of the warp, and two parallel needles 5,5, each introducing a weft thread 6,7.
  • Needles 4,5 are carried on a common member 8 and operate in the same direction and in synchronism, needle t introducing its weft thread 6 above guide bar 2, while needle 5 introduces its weft thread 7 below the said guide bar, into the shed.
  • warp threads 1 and tie-in warp threads 9, are reversed at each weaving cycle.
  • weft threads 6, 7 are placed in the open shed by needles 4,5, where they are held by thread catcher 1 5.
  • a special looping knot is then formed onthe outside of guide bar 2, between weft threads 6,7 and tie-in warp threads 9,10, this :knot being pushed over edge 1 1 of the guide bar at the next reed stop or beaten up location. Due to the thread tension, the threads of the looping knot then loop around the row of links, as shown in greater detail in FIG. 4, and tie them off.
  • tie-in warp thread 9 secures the row of links alternately with a loop 91 lying above it and a loop 92 lying below it.
  • tie-in warp thread 10 operating alternately, secures the row of links with alternate lower loops 1102 and upper loops I01, upper loops 101 passing through upper weft thread 6, while lower loops I02 pass through lower weft thread 7, in the tape.
  • the staggering of the loops formed by threads 9,10 results in the row of links being secured to the tape, in the vicinity of each of the gaps 16 to 20, by one loop laid above and one loop laid below the said row of links.
  • FIG. 4 Shown at the top of FIG. 4 is a finishing stage after a completed weaving cycle, i.c., after reed 12 has stopped and the finalloops of threads 9,10 have been drawn into gap 20, this drawing'in of the loops being effected by appropriate tensioning of weft threads 6,7. At this time, threads 9,10 pass over edge 11 of guide bar 2 towards the tape, whereas the two weft threads 6,7 runs above and below guide bar 2 towards the fabric.
  • the next weaving cycle is initiated by a shed change in warp threads 1 and the return of tie-in warp threads 9,10 which thereafter cross each other, the location 21 of this crossover being on the outside of guide bar 2, i.e., in front of deflecting edge ll.
  • threads 9,10 loop around weft threads 6,7.
  • knot 22 is pushed over edge ll of guide bar 2, whereupon weft threads 6,7 and warp threads 9,110 are again drawn towards the edge of the tape in the manner shown in FIG. 4, and links 3 are again secured to the edge of the tape by one loop above and one loop below.
  • tie-in warp threads 9,10 are the edge warp threads to which the curves 62, 72 between consecutive weft-thread loops 6,6 and 7,7 are secured.
  • thread 9 alternatelysecures-curve 62 of an upper weft-thread loop and curve 72 of a lower loop 7, while thread 10, operating in mirror image, alternately secures the curves-of upper and lower weftthread loops.
  • FIGS. 7 and 8 illustrate a slide-fastener tape in which a different method is used to weave row of links 3 to the edge of the tape.
  • the maindifference between this and the method already described is that tie-in warp threads 9,10 are reversed twice between two Consecutive introductions of pairs of weft-thread ,loops. 6,7. In. this way thread 9 always secures curve 62 of upper weft-thread loops 6, while thread l0 always secures curve 72 of lower weft thread loops 7.
  • the tie-in warp threads are reversed for the first time after each advance of the tape exposing a new gap between the links, whereupon a pair of weft-threads loops 6,7 are introduced, after which the two tie-in warp threads are reversed for the second time; this is followed by the reed stop, and the tape is again advanced.
  • curves 94 and 104 looping around the teeth of the links on both sides, produce a satisfactory guide for the fastener slide.
  • the method described may also be carried out with a single needle alternating between the top and bottom of the guide bar, in which case the weft thread also secures the row of links in the area of the gaps between the links. In this case, however, the weaving speed is lower and a suitable reversing mechanism for the needle must be provided.
  • step (c l) 1. building a new shed with the ground warp threads reversed relative to step (c l) and with the fastening threads in the same shed position as at step (c 3);
  • fastening threads consist of two groups of a plurality of threads.
  • said guide bar extending in the direction of the warp threads and ending at that location where the weft threads are beaten up to the woven tape;
  • said guide bar having an end face which acts as a deflecting means for said tie-in warp threads.
