Definitions

  • warp-knitted tapes for use in the field of slide fasteners or zippers.
  • the knitted tapes have suffered from reduced mechanical strength and less dimensional stability compared to woven fabric tapes, and the fastener elements mounted thereon were prone to become displaced from their properly aligned position or disengaged from the longitudinal inner edge portion of the tape along which they are secured.
  • reinforcing cores were mostly interwoven with fastener tapes of woven fabric.
  • the present invention is therefore aimed at the provision of a warp-knittedstringer tape having a longitudinal inner edge portion for mountinga row of fastener elements, which edge portion is thickened or otherwise rendered sufficiently bulky by the incorporation of a reinforcing core between adjacent wales and fastening weft threads laid in to fasten the core therebetween in addition to weft threads extending transversely in the system of the tape, and which is thus reinforced to provide increased dimensional stability such that the fastener elements can be retained firmly in position therealong against displacement relative to the tape.
  • the term reinforcing core includes relatively thick threads, stranded yarns and the like which may be of textile or plastic materials.
  • FIG. 1 is a diagrammatic view of a warp-knitted stringer tape provided in accordance with a first embodiment of the invention.
  • FIG. 2 is a similar view but showing a second embodiment of the invention.
  • a supporting stringer tape T of a warp-knitted structure comprising wales W W W W and so on which are formed by suitable warp stitches such as open-pillar stitches as shown and weft threads laid in to connect the wales coursewise as is well known in art of warp-knitting.
  • a reinforcing core 11 is provided for strengthening the longitudinal inner edge portion 12 of the tape T along which the fastener elements (not shown) are secured.
  • the core 11 is inserted in an interwale groove 13 formed between the first or innermost wale W and the second wale W at the longitudinal inner edge portion 12 and extends longitudinally substantially to full length of the tape T.
  • additional weft threads 14, 15 preferably thicker or larger than the weft threads 10 for fastening the reinforcing core 11 in place between the first and second wales W and W against displacement relative to the tape T.
  • the weft threads 10 laid in at the longitudinal edge portion 12 are arranged to run alternately over and under the reinforcing core 11.
  • the first fastening weft thread 14 is laid in from one direction to overlie the core 11, while the second fastening weft thread 15 is laid in from the opposite direction 'to underlie the core 11.
  • Successive loops 14a of the first fastening threads 14 alternate with successive loops 15a of the second fastening threads 15 so that their respective turns 14b and 15b are not overlapped or superimposed one upon the other when seen in projection to the place of the stringer tape T.
  • This arrangement ensures that the reinforcing core 11 be stabilized in position with uniform distribution of tension offered by the fastening threads 14, 15 throughout the length of the tape T, and that thus the longitudinal inner edge portion 12 of the tape T be held sufficiently dimensionally stable to support thereon a row of fastener elements in the proper alignment.
  • FIG. 2 shows a modified form of warpknitted stringer tape T according to the invention which is characterized by the provision of two reinforcing cores 11a and 11b which are likewise accommodated in the interwale groove 13 formed between thefirst or innermost wale W and the second wale W at the longitudinal inner edge portion 12. It will be seen that the two cores 11a and 11b are superimposed one upon the other with respect to the plane of the stringer tape T and secured in position by two fastening weft threads 14 and 15 provided in addition to the weft threads 10 which constitute the web of the tape T.
  • the weft threads 10 extending along the longitudinal inner edge portion 12 of the tape T are arranged to run between the two superimposed cores 11a and 11b.
  • the first and second fastening weft threads 14 and 15 are laid in from opposite directions with their respective loops 14a and l5-1-alternating with each other so that the respective t'urns 14b and 15b of these loops at the wales W and W are not overlapped when seen in projection to the plane of the tape T.
  • the first fastening thread 14 overlies the upper reinforcing core 11a, while the second fastening thread 15 underlies the lower reinforcing core 11b, these fastening threads forming a so-called marquisette pattern with the wales W W whereby the two superimposed cores 11a and 11b are anchored firmly in position without being displaced relative to each other.
  • the second embodiment just described is advantageous in that the edge portion 12 of the tape is thickened to provide greater stability as regards the dimensions and form of the tape T as desired for mounting fastener elements of relatively large size.
  • a supporting stringer tape for slide fasteners which comprises a warp-knitted structure comprising wales of longitudinally extending warp stitches connected coursewise by transversely extending weft threads, a reinforcing core inserted between two adjacent wales at the longitudinal inner edge portion of the tape along which a row of fastener elements is secured, and a first fastening weft thread laid in from one direction to overlie said reinforcing core and a second fastening weft thread laid in from the opposite direction to underlie said reinforcing core, said first and second fastening threads interconnecting at least said two adjacent wales.
  • a supporting stringer tape for slide fasteners which comprises a warp-knitted structure comprising wales of longitudinally extending warp stitches connected coursewise by transversely extending weft threads, two reinforcing cores superimposed one upon the other with respect to the place of the tape and inserted between two adjacent wales at the longitudinal inner edge portion of the tape along which a row of the fastener elements is secured, and a first fastening weft thread laid in from one direction to overlie the upper one of said two reinforcing cores and a second fastening weft thread laid in from the opposite direction to underlie the lower one of said cores, said first and second fastening threads having their respective turns spaced one from another longitudinally along said two adjacent wales, and said transversely. extending weft threads at the longitudinal inner edge portion of the tape passing between said upper and lower cores.
