Definitions

  • the two coils, with attached ta again just downstream of the sewin tion can include a pair of plates defi ch serves to hold the coils and ta mesh them together immediately afterwards.
  • the present invention relates to a method of manufacturing slide fasteners and an apparatus for carrying out the method. More specifically, this invention concerns slide-fastener stringers having two synthetic-resin monofilament coils each of which is attached to the edge of a textile support tape.
  • the first comprises the simple steps of sewing each coil to its respective support tape, and thereafter matching up the stringer half so formed with another stringer half similarly made.
  • Such a method makes it possible to sew at high speed and thereby produce a great number of fasteners in a small amount of time.
  • fasteners often are crooked since the spacing between the teeth of one half differs from that between the teeth of the other half imparting to the finished fastener a tendency to bow.
  • Another method which avoids this problem of bowing provides for the simultaneous manufacture of both stringer halves by sewing both tapes to two interleaved coil at the same time.
  • This method is advantageous in that it ensures that the spacing remains perfectly the same between adjacent teeth on the coil, and, since synthetic-resin coils are often made by winding two synthetic-resin monofilaments in opposite directions over each other on a mandrel, in that it permits the use of the two coils in the interleaved condition.
  • the disadvantage of such a method is great; the sewing must be done carefully and slowly since the needles must just engage within the exposed bights of each turn without hitting the teeth. Thus, a high-quality fastener is produced, but slowly.
  • an object of the present invention to provide an improved method of and apparatus for manufacturing slide-fastener stringers.
  • Another object is to provide such an apparatus and method which overcome the above-given disadvantages while retaining the above-given advantages.
  • Yet another object is to rovide a method which can be carried out on conventional apparatuses with changes not requiring complete rebuilding of the sewing machines.
  • the two coils can be separated and then fed through a series of guides which keep the interturn spacing the same by tensioning the two coils to the same extent and/or by making them both travel along paths of identical length.
  • FIG. I is a perspective, partially broken away, and partially diagrammatic view of the apparatus for carrying out the method ofthe present invention.
  • FIGS. 2 and 3 are views taken along line ll-ll and III-III of FIGS. 1 and 2, respectively;
  • FIG. 4 is a view similar to FIG. 3 showing an alternative embodiment ofthe present invention.
  • FIG. I An apparatus having a supply 6 of a pair In of interleaved coils.
  • the pair la is separated by a pin 13a extending across an opening 13c in a member 13b forming a separator 13 that divides the pair 10 into two coils 1.
  • These two coils 1 then pass between a first pair 9 of guide rollers ineluding a driven roller 9a formed with coil-receiving circumferential grooves 9d and an idler roller 9b both mounted on a member 9c pivoted at 9f and urged by a spring 9e in the counterclockwise direction to tension the two coils 1.
  • the two coils l extend substantially parallel to each other to a pair of guide eyes 12 mounted on wires 12a fixed to a pivotal shaft 12b coupled to a potentiometer 21. Thence the coils 1 pass over idler rollers 9g formed with grooves 9i and mounted on a fixed plate 9h.
  • a second roller 9g can also be mounted on this plate 911, or three or more can be provided in order to make several stringers 3 simultaneously.
  • a roller assembly 8 comprising a smooth cylindrical idler roller 8a and a longitudinally ridged driven roller 81; formed with circumferential coilreceiving grooves 8c and being supported by its drive shaft 8f on lugs 8d of a fixed support 8e.
  • a pair of support tapes 2 actually two pairs for the apparatus here shownis fed to the roller assembly 8 past a guide 14 which spaces them exactly parallel to each other.
  • Each tape 2 is juxtaposed with one of the coils l and they are all thence fed to a sewing station 10 under a vertically reciprocable block 5 mounted on a rod 5a of a sewing assembly 5b and carrying a needle 4 for each coil 1 and engageable through this coil 1 to fix it to its respective support tape 2.
  • roller assembly 7 Downstream of the sewing station 10 is a roller assembly 7 comprising an upper roller 7a mounted on a downwardly biased fork 7b and a lower longitudinally ridged cylindrical driven roller 76 formed with a single circumferential groove 70' adapted to receive the interleaved coils 1.
  • the roller 70 has a drive shaft 7e coupled, along with the shafts of rollers 9a and 8b to a drive motor 22 which is controlled by the potentiometer 21.
  • This motor 22 also is coupled to the sewing drive unit 5b.
  • the potentiometer 21 will regulate the motor 22 to decrease the speed of roller assemblies 9 and 7, as well as that of the sewing unit 5b.
  • FIGS. 2 and 3 show the sewing station 10 in greater detail. It comprises basically a pair of plates 10b and held together by screws 10d.
  • the plate 10b is formed with holes 20 staggered in the transport direction shown by the arrows 23 for passing the needles 4.
  • the plate 10b is formed with a wide shallow groove 15 which is separated into two branches at its upstream portion by a web 18. This groove 15 acts only as a guide for the tapes 2.
  • the plate 10b is further formed with a Y- shaped groove having a pair of anns l6 and a leg 19, the arms 16 being separated by the web 18.
  • the width and depth of the groove l6, 19 are dimensioned to snugly and slidably receive the coils 1 underneath the tapes 2.
  • the two coils 1 are forced together and interleaved, just as is done in a slide-fastener slider, to form a coupled slide-fastener stringer 3 (see FIG. 1).
  • This interleaving region 11 is downstream of the needles 4 so that the coils 1 are sewn to the tapes 2 in the uncoupled condition, but immediately thereafter the two stringer halves l, 2 are interleaved.
  • the plate 10b is also formed with slots 17 allowing throughpassage of the needles 4, which in his case attach the slide-fastener advantageously from the back.
  • FIG. 4 shows an alternative embodiment wherein a plate 10b is formed with a groove 19' having an island 18' directly between the slots 17 accommodating the needles 4.
  • the separator 13 can be eliminated and the two coils maintained coupled together-appropriate grooving of all the guide roller-up until immediately before the sewing location since the needles 4 straddle the island 18, and then recoupled immediately afterwards.
  • a method of attaching a pair of synthetic-resin monofilament coils to a pair of support tapes for the manufacture of a slide-fastener comprising the steps of:
  • said guide means includes withdrawal means for pulling said coils and tapes out of said station, said withdrawal means including a pair of rollers engaging said tapes and said coils, said apparatus including means for synchronously driving both of said pairs of rollers.
  • said guide means includes at least one idler roller, the separated coils passing over and around said idler roller.
  • said apparatus includes a reciprocable element bearing a pair of needles each engageable through one of said coils and one of said tapes.
