Definitions

  • a slide fastener comprising a pair of opposed carrier tapes and rows of interlocking fastener elements mounted thereon.
  • Each tape consists of a warp-knitted structure having wales of warp stitches connected coursewise by laid-in weft threads and alternated with grooves wider than said wales. These grooves are substantially filled with reinforcing warp threads to attain dimensional stability of the tape particularly at the longitudinal edge thereof along which the fastener elements are secured.
  • This invention relates toslide fasteners and has particular reference to fasteners comprising a pair of opposed carrier tapes generally of a warp knitted structure and rows of interlocking fastener elements attached along one or inner longitudinal edges of the reers made of woven fabric stringer tapes.
  • fasteners comprising a pair of opposed carrier tapes generally of a warp knitted structure and rows of interlocking fastener elements attached along one or inner longitudinal edges of the reers made of woven fabric stringer tapes.
  • fasteners have suffered from reduced mechanical strength and less dimensional stability compared to woven fasteners. Attempts have been made to improve these factors for instance by employing different kinds of knitting yarns, or by laying warp threads in between wales of the knitted system. None of these attempts were successful.
  • a slide fastener comprising a pair of opposed carrier tapes of a warp-knitted structure, rows of interlocking fastener elements mounted thereon, each of said tapes having wales of warp stitches connected coursewise bylaid-in weft threads and alternated with grooves greater in width than said wales, a plurality of reinforcing warp threads adapted to fill said grooves substantially waleto-wale and a line of sewing stitches securing said rows of fastener elements to said carrier tapes and running through the filled grooves adjacent the respective
  • a pair of warp-knitted carrier tapes which has a mechanical strength and a dimensional stability comparable to those of woven fabrics particularly at the longitudinal edge portion of the'ca'rrier tape along which fastener elements are secured, thereby maintaining the fastener elements in the properly aligned position on their respective carrier tapes during the opening and closing operation of the fastener.
  • a first embodiment which 1 comprises a pair of opposed carrier tapes T, T each tener elements E are secured into position.
  • These grooves 11 are adapted to receive therein a plurality of warp threads 12 in a manner to cover the bottom wall of the grooves and fill the same substantially wale-towale as shown.
  • This arrangement provides reinforcement particularly at an-extreme inner edge region of the tape T defined between the first and second wales W W or corresponding to the innermost groove 11,
  • the fastener elements E shown as being interlocked are secured to the inner edge of the tape T by a, line of sewing stitches S spanning between the leg portion Ea of the fastener element E and the innermost groove 11, running through a stiffening core 13 and the innermost groove 11 and extending longitudinally of the tape T.
  • FIG. 3 is a magnified plan view of another embodiment of the invention.
  • FIG. 4' is a sectional view of the same
  • FIG. 5 is a magnified plan view of a further embodiment of the invention.
  • FIG. 6 is a sectional view of the same.
  • the reinforcing warp threads 12 which are intimately compacted together within the groove 11 serve to hold the sewing stitches S firmly in place under the tension of the warp threads 12 which are directed laterallyt owards each other. This will maintain the proper position and posture of the fastener elements E under severe stresses applied by a reciprocating slider 30 (shown in FIG. 4) or against lateral forces tending to pull apart the closed stringers.
  • the second embodiment shown in FIGS. 3 and 4 considers the dimensional stability both warp-wise and weft-wise of the tape.
  • the fastener shown in FIGS. 3 and 4 is provided with a thickened, reinforced edge 15 extending longitudinally of the tape T and formed by wales W W and innermost groove 11 defined thereby, which groove is substantially wider than the remaining grooves 11 in the tape T.
  • the reinforced edge or element-mounting edge 15 has more reinforcing warp threads 12 and more laid-in weft threads a than there are in the remaining portion or web 16 of the tape T, so that at least the said edge of the tape T retains increased dimensional stability in both longitudinal and transverse directions and hence, the elements E mounted thereon are maintained stably in position against displacement relative to the tape under severe stresses applied by the slider 30, or against lateral forces tending to pull apart the closed stringers.
  • the third embodiment or modification of the fastener according to the invention shown in FIGS. 5 and 6 is intended to provide a densified reinforced longitudinal edge comprising a plurality of reinforcing warp threads 12a thicker than those warp threads 12 laid-in at the remaining web portion 16 of the tape T and intercrossed with a plurality of laid-in weft threads 10a.
  • the reinforced edge portion 20 of the tape T has the innermost groove 11 swollen to a level nearly flush with the first and second wales W W and thus simulates a woven fabric structure and thus has a mechanical strength and dimensional stability comparable thereto.
  • the fastener elements'E when mounted on the fastener in a manner already described are securely held in position on the densified, reinforced edge 20 against displacement by lateral forces or under severe stresses applied by the slider 30.
  • the innermost groove 11 in the reinforced edge 20 is wider than the remaining grooves 11 in the web portion 16 of the tape T in a manner similar to the second embodiment.
  • a slide fastener comprising a pair of opposed carrier tapes of a warp-knitted structure, rows of interlocking fastener elements mounted thereon, each of said tapes having wales of warp stitches connected coursewise by laid-in weft threads and alternated with grooves greater in width than said wales, a plurality of reinforcing additional warp threads filling the bottom of said grooves substantially wale-to-wale solely along the longitudinal edge portion of said tape and a line of sewing stitches securing said row of fastener elements to said carrier tape and running through said additional warp threads in said groove adjacent the longitudinal edge of said carrier tape.
