Abstract
Two or more warp-knitted members of a tubular or cylindrical shape are interconnected by a connecting thread to provide reinforcement to be inserted longitudinally in a row of helically coiled fastener elements. The tubular warp-knitted members may be wrapped around core members. A choice is available of diameters of the warp-knitted members so as to be compatible with the particular shapes and contours of given fastener elements. A plurality of warp-knitted members are interconnected in such a fashion that the resulting reinforcement can be adapted for securing a relatively large-size fastener element onto the tape.
Claims3
A reinforcement for a slide fastener comprising a plurality of cylindrical, warp-knitted members having needle loops and sinker loops interconnected therewith, said sinker loops extending in diagonally criss-crossed relation to each other and alternately over and under said needle loops to define a plurality of warp-knitted members each having a generally tubular knitted configuration, and a connecting thread laid in weftwise to interconnect said plurality of warp-knitted members transversely in parallel, spaced-apart relation to each other.
