ABSTRACT:
A slide fastener stringer comprises an elongate molded coupling element strip woven into a stringer tape along a longitudinal edge thereof. The strip includes a succession of laterally spaced coupling elements each having a pair of first and second legs, and a pair of series of first and second connecting portions extending respectively between alternate pairs of the first legs and between alternate pairs of the second legs in staggered relation with each other. A pair of connector threads is partially embedded in the first and second legs, respectively, of each coupling element and extends parallel to the first and second connecting portions, respectively, on the head side of the coupling elements. Each of the coupling elements has a pair of grooves extending transversely through a pair of first and second legs, respectively, on their outer sides, and disposed remotely from the connecting portions and from the connector threads. A pair of anchor threads is disposed in the grooves in the first legs and the grooves in the second legs, respectively, along the full length of the strips. A weft thread of the tape has a plurality of loops each encircling one of the first and second connecting portions, the connector threads, and the anchor threads between adjacent coupling elements, the weft loops being held out of contact with the connector threads.
