Definitions

  • Slide fasteners for closing the fly of a trouser are, during the manufacture of trousers, first connected to socalled fly strips and the latter then sewn with the slide fastener connected thereto onto the corresponding trouser parts.
  • Such fly strips for trousers are manufactured from the same material as the trouser itself and the narrow strips have an upper edge which extends normal to th longitudinal direction of the strip whereas the opposite end is curved.
  • the fly strips are formed from fabric ma- 'terial which has, as each fabric material a front side and a reverse side, and it is required that in the finished and closed trouser the upper, that is the left fly strip faces with its so-called front side the front side of the lower, that is the right fly strip.
  • pairs of fly strips are connected to the two slide fastener halves which are taken from a supply of two continuous and engaged slide fastener stringers, i.e., a continuous slide fastener chain.
  • the method according to the present invention for simultaneously connecting a pair of continuous slide fastener stringers to fly strips of trousers or similar garments mainly comprises the steps of feeding consecutive pairs of fly strips in longitudinal direction with the strips in each pair arranged transversely spaced from and mirror symmetrically arranged with respect to each other and with the faces of the strips, which in the finished trouser face each other, facing upwardly, to a pair of transversely spaced and synchronously driven stitch forming means, taking a continuous slide fastener chain with the coupling elements on the two stringers thereof engaged with each other from a supply of such a continuous slide fastener chain, disengaging the coupling elements so as to separate the two stringers of the slide fastener chain from each other and reversing one of the stringers through so that that edge of one stringer which carries the coupling elements faces the edge of the other stringer which is free of coupling elements and feeding the two stringers in the thus obtained position into engagement with the aforementioned faces of the fly strips and subsequently thereto sewing the
  • FIG. 1 illustrates the fly in a pair of trousers in open condition with the fly strips and the slide fastener stringers attached thereto;
  • FIG. 2 illustrates in schematic manner a cross section through a pair of fly strips with the slide fastener stringers attached thereto, whereby fly strips and stringers are shown for reason of clarity spaced from each other;
  • FIG. 3 schematically illustrates the position of the fly strips and the slide fastener stringers during attachment thereof to each other according to the prior art
  • FIG. 4 illustrates schematically the position of the fly strips and the slide fastener stringers during attachment thereof in accordance with the present invention.
  • FIG. 1 schematically illustrates the fly in a pair of trousers with the fly strips and the slide fasteners connected thereto in open condition
  • FIG. 2 schematically illustrates in cross section the relative position of the slide fastener and the two fly strips at which these elements are arranged when connected to the trouser material at the fly.
  • each fabric material has a front side and a reverse side and the front sides or front faces of the fabric material from which the fly strips 4 and 5 are formed have to be arranged in such a manner that in the finished trouser the front side's of the two fly strips face each other.
  • these front sides are indicated in FIGS. 2-4 by closely spaced hatch lines.
  • the closed slide fastener comprising the two stringer tapes with the coupling element 3 thereon has to be arranged between the upper fly strip 5 at the left side of the trouser and the lower fly strip 4 at the right side of the trouser whereby the front sides of the two fly strips have to face each other.
  • the slide fastener half 1 is usually connected to the upper fly strip 5 by a two thread seam 8 which is passed through the fly strip 5 at a certain distance from the right edge thereof, as viewed in FIG. 2 and the upper fly strip 5 is covered with an outer fabric layer, not shown in FIG. 2, which is sewn to the fly strip 5 in such a manner that the lateral portion thereof projects toward the right beyond the seam 8 in such a manner to cover the slide fastener 1, 2.
  • the other slide fastener half 2 is usually connected to the corresponding fly strip 4 with a single thread seam 9.
  • the outer fabric layer is connected to the fly strip 4 in the region of the seam 9, as shown in FIG. 1.
  • FIG. 3 schematically illustrates the manner in which a fastener is connected to a pair of two fly strips according to the prior art.
  • the slide fastener 1, 2 is fed through the sewing machine in coupled condition, that is the coupling elements 3 on the two slide fastener stringers 1 and 2 are engaged with each other and the upper fly strip 5 is superimposed on the slide fastener whereas the latter is superimposed on the lower fly strip 4 substantially as shown in FIG. 2, however, before the thus superimposed elements reach the sewing machine, the right lateral portion of the upper strip is upwardly bent as shown in FIG.
  • the method according to the present invention was developed in order to avoid the above-rnentioned disadvantages of the method according to the prior art as illustrated in FIG. 3.
  • FIG. 4 The relative arrangement of the two fly strips 4 and 5 of the slide fastener halves 1 and 2 with the coupling element 3 thereon during sewing of the slide fastener halves to the respective fly strips in accordance with the method of the present invention is schematically illustrated in FIG. 4.
  • the two fly strips 4 and 5 are arranged spaced from each other a sufficient distance so that the attachment seams 8 and 9 can be formed without mutual interference and the two fly strips 4 and 5 are fed in longitudinal direction and spaced from and mirror symmetrically arranged with respect to each other to a pair of correspondingly spaced and synchronizingly driven stitch forming means of a sewing machine or the like.
  • the pair of fly strips are preferably fed toward the sewing machine with the curved ends leading, however, it is also possible to feed the fly strips with their straight edge ends, which form in the finished trouser construction the upper edges thereof, as the leading ends. It is also not necessary that, as shown in FIG. 4, the fly strip 4 which in the finished trouser construction forms the lower fly strip be arranged at the left side, as viewed in FIG. 4 and the fly strip 5 on the right side, but it is possible to reverse the position of the two fly strips from the position as shown in FIG. 4. Essentially, however, is that the front sides or faces of the fabrics forming the fly strips 4 and 5 face upwardly as shown in FIG. 4.
  • the slide fasteners 1, 2 to be sewn to the two fly strips is taken from a supply, for instance a spool on which a continuous slide fastener chain is wound up with the coupling elements of the two stringers of the chain engaged with each other.
  • a supply for instance a spool on which a continuous slide fastener chain is wound up with the coupling elements of the two stringers of the chain engaged with each other.
  • the coupling elements on the two stringers 1 and 2 are disengaged so as to separate the two stringers 1 and 2 from each other and one of the stringers is reversed through relative to its longitudinal direction with regard to the other stringer so that the coupling element 3 on the stringer 1 will then face the edge of the stringer 2 which is free of the coupling elements as shown in FIG. 4.
  • the stringer 1 is sewn to the fly strip 5 with the two thread seam 8
  • the stringer 2 is sewn to the fly strip 4 with a single thread seam 9.
  • the above-described method according to the present invention has the advantage over the method according to the prior art that complicated fabric deflector means which are difficult to operate are avoided.
  • suflicient to provide two sewing machines which are arranged opposite each other and which are synchronously driven which permits in a very simple manner obtain the spacing between the two attaching seams.
  • a method for simultaneously connecting a pair of continuous slide fastener stringers to fly strips for trousers or similar garments comprising the steps of feeding consecutive pairs of fly strips in longitudinal direction with the strips in each pair arranged transversely spaced from and mirror symmetrically with respect to each other and with the faces of the strips, which in the finished trouser face each other, facing upwardly, to a pair of transversely spaced synchronously driven stitch forming means; withdrawing a continuous slide fastener chain with the coupling elements on the two stringers thereof engaged with each other from a supply of such a continuous slide fastener chain; disengaging said coupling elements so as to separate the two stringers of the chain from each other and reversing one of the stringers through so that that edge of one stringer Which carries the coupling elements faces the edge of the other stringer which is free from coupling elements and feeding the two stringers in the thus obtained position into engagement with said faces of said fly strips; and sewing the stringers and the fly strips in the thus engaged position to each other.
  • each of the fly strips has one straight side edge and an opposite curved side edge, and wherein said pair of fly strips are fed to the stitch forming means with the straight edges facing each other.
  • each of said fly strips has one straight side edge and an opposite curved side edge, and wherein said pair of fly strips are fed to said stitch forming means with said curved edges facing each other.
  • one of said stringers is sewn to the correspondingly fly strip with a two thread seam and the other with a one thread seam.
