Definitions

  • the present invention relates to an open end slide fastener, particularly for knitwear.
  • an open end slide fastener of the kind comprising a pair of woven or knitted tapes, having respective top ends and bottom ends and carrying respective pluralities of coupling elements, a slider movable along said tapes to mutually engage or disengage said coupling elements, and a stop member fixed at the bottom end of one tape, and adapted to stop the slider and to detachably receive an end coupling member which is fastened to the bottom end of the other tape and introduced through the slider; a reinforcement sheet member made of plastic material being permanently affixed to at least one face of the bottom end portions of the tapes, adjacent the stop member and the end coupling member, respectively.
  • Open end slide fasteners of the above-defined kind are widely in use, particularly in garments and the like.
  • a slide fastener 1 of that kind comprises a pair of tapes 2, 3, made of a woven or knitted material.
  • the tapes 2, 3 have respective top ends 2a, 3a and respective bottom ends 2b, 3b.
  • a respective longitudinal edge of each tape 2, 3 is provided with a respective plurality of coupling elements 4, 5, such as interlockable teeth.
  • the slide fastener 1 further includes a slider 6 which in a per se known manner comprises a slider body 6a, a so-called crown 6b and a pull tab 6c.
  • a slider 6 which in a per se known manner comprises a slider body 6a, a so-called crown 6b and a pull tab 6c.
  • respective end coupling members 9, 10 are fastened to the tapes 2, 3.
  • a bottom stop member 11 is permanently fixed to the bottom end of one tape, for instance tape 3, and is adapted to stop the slider 6, and to detachably receive the end coupling member 10 which is fastened to the bottom end 2b of the other tape 2, which is in use preliminarily introduced through the slider 6.
  • the slide fastener 1 of figure 1 is of the open end kind, i.e. of the kind in which, by drawing the slider to its lowermost position, namely against the bottom stop member 11, it is possible to "open" the slide fastener by disengaging the end coupling member 10 from the bottom stop member 11 and the slider 6.
  • the reinforcement sheet members 12, 13 are made for instance of a woven polyamide or polyester having a structure such as that of a so-called "taffeta".
  • the reinforcement sheet members 12 and 13 are disposed astride the lowermost edges of the two tapes 2, 3, and extend on both sides of said tapes.
  • a slide fastener of the above-described kind can be attached to a piece of knitwear by affixing to each of two mating portions thereof a respective tape of the slide fastener, by means of a conventional sewing machine.
  • a linking machine for knitwear includes a linear (circumferential) array of fixed guide needles or points, onto which each tape of a conventional slide fastener without the reinforcement sheet members, and the corresponding mating portion of the knitted garment are to be pressed, so as to make said needles pass therethrough. Thereafter each tape is fastened to the corresponding garment portion through a series of stitches formed by means of a moving crochet needle which cooperates with said fixed needles.
  • an open end slide fastener of the previously defined kind characterised in that the bottom end portions of said tapes are provides with at least one respective longitudinal row of uniformly spaced apertures, extending through the tapes and the said reinforcement sheet members and adapted to receive a stitch-forming thread.
  • FIG. 2 A first embodiment of the invention is shown in figure 2.
  • parts and components which have already been described in connection with figure 1 have been attributed once again the same reference numerals.
  • the bottom end portions 2b, 3b of the tapes 2, 3 are provided each with at least one respective longitudinal row of uniformly spaced apertures 14, extending through the tapes 2, 3 and through the associated reinforcement sheet members 12, 13.
  • the apertures 14 of the embodiment shown in figure 2 are through holes, having preferably an essentially circular shape.
  • Said apertures or holes 14 are adapted to receive a stich-forming thread in a linking machine.
  • Figure 3 shows a portion of a linking machine, such as the machine Model 99VE manufactured by the Italian company CONTI Complett.
  • a linking machine such as the machine Model 99VE manufactured by the Italian company CONTI Complett.
  • said tape 3 is pressed onto the array of fixed needles 50 of the linking machine, so as to make said needles 50 pass therethrough close to the coupling teeth 5.
  • the provision of the apertures 14 in the bottom end portion 3b of tape 3 allows said bottom end portion to be easily pressed onto the needles of the linking machine.
  • the corresponding mating portion of the garment can then be in turn positioned in the machine, by making the needles 50 pass therethrough. Thereafter, tape 3 of the slide fastener is fastened to the garment portion, by the provision of a series of stitches formed by means of a moving crochet needle (not shown in figure 3) which cooperates with the fixed guide needles 50.
  • figure 2 provides optimum results if the through apertures 14 provided in the bottom end portions 2b and 3b of the tapes 2 and 3 are positioned substantially at the same distance between the fixed needles 50 of the linking machine intended to be used.
  • the bottom end portions 2b, 3b of the tapes 2, 3 are provided with a respective longitudinal row of uniformly spaced apertures 114, each of which is essentially formed of two orthogonally intersecting cuts.
  • the apertures 114 have an essentially cross-like shape.
  • the longitudinal portions of the apertures 114 allow to accommodate the tapes 2, 3 onto the fixed needles of linking machines having slightly different pitch distances between the said needles.
  • each tape 2, 3 of the slide fastener is a woven tape including a plurality of longitudinal warp threads, at least one of which is made of a thermally-soluble material.
  • Said at least one thermally-soluble warp thread is conveniently aligned with the corresponding row of apertures 14 or 114 of the tape 2 or 3, and allows to create, through the thermal elimination of said warp threads, a weakened line along the tapes, through which it is easier to cause the penetration of the fixed needles 50 of a linking machine when the tape is to be affixed to a knitted garment portion.
