Definitions

  • ABSTRACT A method of the production of a slide fastener by weaving, which comprises the steps of bending over a continuous profile strand about a loop forming core within the range of the weaving point for the formation of a row of coupling members, and guiding back and forth the profile strand of synthetic material as a warp thread shedding through the weaving plane. Therebythe profile strand is guided in a cycle, at some points reversing about the loop forming core, and binding the profile strand within the range of the rearward return points by means of at least one woof thread loop.
  • the present invention relates to a method of production of a slide fastener by weaving, whereby within the range of the weaving area for the formation of a row of dome members a continuous profile strand of synthetic material is turned around a loop-forming hook and bound in a band fabric.
  • Woven slide fasteners in which the windings of the rows of dome members are created by reciprocation of a weft thread consisting of synthetic material during the weaving, have the drawback, that the weaving process can be performed only with two shuttles at a comparatively low working speed.
  • the member forming warp thread is disposed thereby alternately on one or the other side of the loop forming hook.
  • the member forming warp thread should move additionally to its weaving stroke movements in a cycle move laterally outwardly.
  • the member forming warp thread is lowered below the weaving plane, in order to be overgripped by the weft insert.
  • the guidance of the member forming warp thread concerning the loop forming hook takes place in a manner of a leno weave, where the hook forms the setting thread" and the member forming warp thread the pile thread, which in relation to the loop forming hook is zig-zag-shaped and is brought in reciprocating manner from one side of the hook to the other and back again.
  • the loop forming hook which forms the axis of the piles after tying of the member forming warp thread, is withdrawn again completely from the woven product, so that the windings of the member forming warp thread remain and the finished row of members is created.
  • a non-objectionable woven slide fastener can be produced in a particularly simple manner.
  • the member forming profile strand, working as a warp thread permits high working speeds during the weaving.
  • the warp thread can be selectively long, whereby a stopping of the weaving due to emptying of the thread storage practically does not play any significance. Since the dome members are produced directly during the weaving of the carrying bands, the latter are not only in exact adjustment to the weaving, rather are also gripped at the desired point by the warp threads, without providing therefor any particular measures and additional devices.
  • the cross section of the dome members results from the size and form of the hook.
  • the weft succession and the weaving removal determine the distance between adjacent dome members.
  • the weft insertion itself can take place in any of the known manners by example by means of shuttles.
  • the interconnection of the loop ends takes place suitably on the edge of the carrying band woven product disposed opposite the row of dome members.
  • the present invention is directed, however, also to an apparatus for performing of the previously mentioned method where a movable thread guide and a hook is used.
  • the present invention is characterized relative to the known structures preferably such, that in the thread guide a member forming warp thread is received and by means of the thread guide alternately on one or the other side of the hook formed as a loop forming hook is insertable into the range of the tying position. In order to obtain a non-objectionally thread performance along the loop forming hook up to the tying position, it is advisable, to equip the hook in this range with an angular arrangement.
  • FIG. 1 is a partly perspective view of the weaving position range of the sliding fastener, whereby the conventional parts of the loom have-been omitted for a clearer showing while, however, the thread guide for the member forming warpthread is shown;
  • FIGS. 2a to 5a are schematic plan views of the weaving point of the sliding fastener in different working steps
  • FIGS. 2b to 5b are schematic showings of correspending side elevations of the weavingpoint for the different previously mentioned working steps.
  • FIG. 6 is a schematic working scheme for the working movement of the thread guide device for the guidance of the member forming warp thread during the different working steps in accordance with the previous Figures.
  • FIG. 1 for the weaving production of the slide fastener 10 within the range of the carrying band part are provided in addition to a greater number of warp threads 11 a continuously woven-in weft thread 12, while for the formation of a row of dome members 13 a profile strand 14 of synthetic material is woven-in in the edge range of the woven product.
  • This profile strand is guided'as member-forming warp thread 14. It performs corresponding with the working manner of the warp 11 in the section in front of the shuttle abutment position l6, the formation of a shed l7 through which by the next following shuttle insertion a further part piece of the weft thread 12 is fed through.
  • a weft insertion means serves here a shuttle, which is not particularly shown, as well as the weaving comb abutting the weft thread 12 is omitted. Finally also the conventional weft shafts are not shown, which by the formation of the shed 17 spread the web threads 11 into an upper warp thread shed 18 and a lower warp thread shed 19.
  • the member forming warp thread 14 is not moved however up-and downwardly alone in a stroke movement 22, whereby it reaches a high position or a low position, rather it is subjected to a displacement movement 23 in form a type of a leno weave.
  • the warp thread 14 cooperates thereby with a loop forming core 20 in the manner of a leno weave.”
  • the member forming warp thread 14 is moved from one side of the core to the other and back again in the manner of a loop thread relative to the loop forming core 20, whichperforms the function of a setting thread, reversing in a cycle from one side of the hook to the other and again reversed. This movement is produced by a particular thread guide 21 for the warp thread 14.
  • the thread guide v21 comprises guide sleeves 24, which perform by means of a rod arrangement, not particularly shown,-as well as the complementing excentries a vertical upward and downward movement 22 in the'direction-of the arrow shown in the drawing.
  • a guide rod 25 which performs by means of a purther, not particularly shown excentric drive, a horizontal movement 23 in the direction of the double arrow.
  • the guide rod 25 serves as a carrier for a guide needle 26, through its guide eye 27 of which the member forming warp thread 14 is threaded through.
  • the guide rod 25 is suitably extended over the total width of the loom, by mounting the same in additional guide sleeves, whereby on each weaving position a corresponding guide needle 26 is provided for a member forming warp thread.
  • the member forming warp thread 14 is disposed at-first to the right from the loop forming hook 20, if one looks towards the goods removing direction 28 onto the weaving point.
  • the member forming warp thread 14 is in view of the position of its thread-guiding element (not shown) in the range of the low position 19 of the remaining warp threads.
  • the loop forming hook 20 is disposed starting from an angular arrangement 40 within the range of the shuttle abutment point 16, within the range of the high position 18 with its unbound end. After spreading of the shed 17 it comes not to the insertion of a thread part a.
  • the warp insertions occur in loop form as a double thread.
  • the warp insertion needle 29 is inserted from the band edge equipped with rows of dome members into the shed 17, while on the member free opposite weaving edge 30 the loop ends 31 of the warp are pulled about the previous loop end, whereby at this edge 30 a row of loops is formed drawn continuously into each other.
  • the warp thread 14 disposed during the previously stated warp thread insert above the loop forming hook forms now in the presentwarp thread insert a loop arm 32 which is disposed above the hook 20, by the warp thread parts a overlapping the warp thread insert.
  • a care is taken that the warp thread 14 is gripped and is bound to the weave.
  • the warp thread insert exerts thus here the function of a member tie-in.
  • the warp insert a is pressed to the shuttle abutment point 16 by a comb which is not shown.
  • the warp threads 11 are spread in a different distribution to their high positions 18 and low positions 19, respectively, for the formation to the next shed 17, as it is prescribed by the weaving binding.
  • the loop forming hook 20 is disposed unchanged still in the high position 18.
  • the member forming warp thread 14 is now transformed by its thread guide into the high position 18 of the shed 17.
  • the warp thread 14 is not gripped, so that, it leads now only to a continuation of the carrying band part 15.
  • this warp insert b is bound in the manner of a loop with the previous loop end 31 of the previous warp insert a, which is taken care of by a crochet needle (not shown), the appearance, function and working manner is known.
  • the warp threads are spread for the formation of the shed in the high position 18 and the low position 19 in the correct distribution.
  • the member forming warp thread 14 is again in the low position, while the loop forming hook 20 is disposed unchanged within the range of the high position 18.
  • the member forming warp thread 14 is again over-lapped and bound by its warp thread parts to the fabric, for which reason one could characterize this shuttle insert in its particular function as member binding shuttle.
  • the member warp thread is brought to the left side of the loop forming hook 20, as it is shown in FIG. 4a.
  • the member forming warpv thread is pulled below the loop forming hook 20 into the fabric as it is indicated in FIG.
  • a bow-shaped rearward reversing position 36 is thereby created, which is disposed below the loop forming hook 20.
  • the warp thread loop inserted as a double thread, is suspended with its end 31 with the previous loop 31 in loop form.
  • a further loop arm 35 disposed below the hook 20 is created.
  • the pulling through of the rearward bow 36 below the loop forming hook 20 can be simplified by step wise release of the thread tension in the member warp thread 14 at this working type point. It is feasible to provide additional control devices for this movement of the member warp thread.
  • this working step is terminated andit leads to the last working step in the present'cycle of the weaving process, which is shown more clearly in FIGS.'5a and 5b.
  • the member warp thread 14 is disposed in the top plan view of FIG. 5a
  • the angular. formation 40 of the loop forming hook 20 is significantly within the range of a warp abutment position 16, because the formed loops 32, 34, 35 and 37 move on the inclined hook as on a ramp by itself against the warp abutment position 16, in order to be bound there in the manner of a warp.
  • the actual engagement loops 30 and 39, causing a coupling, come to lie, which engagement loops 30 and 39 are brought into engagement in the finished slide fastener with mirror-like inserted coupling members.
  • the formation of dome faces in this loop part 38' and 39 can be favored by previous deformations of the warp thread 14. By weakenings of the cross section it would be further simplified to form the rearward reversing position 33 and 36.
