ABSTRACT:
A coupling element assembly for slide fasteners includes a row of laterally spaced coupling elements made of synthetic resin. A pair of warp-knit elongate webs extend transversely of the coupling elements and are embedded respectively in a pair of leg portions of each coupling element to interconnect the coupling elements. Each of the warp-knit webs comprises at least one first thread forming a wale of chain stitches and a second thread interlaced or interknitted with the first thread. The warp-knit webs have roughened surfaces having interstices into which material of the coupling elements enters for secure anchorage of the coupling elements. At least one third thread may be interlaced or interknitted with the first threads and has portions spaced longitudinally of the first threads and embedded longitudinally in the coupling elements.
