ABSTRACT:
A slide fastener comprises two continuous plastic filaments (synthetic-resin monofilament), each with a multiplicity of generally helicoidal coupling elements for interlocking with the coupling elements of the opposite filament, each filament being woven integral with the threads of its respective support tape to form a tape-like unit. Each coupling element has a coupling head on a loop end and a pair of shanks terminating in bight portions which connect elements of the same tape-like unit. The shanks of each coupling element, which separate the bights from the loops, are held in close abutment by warp threads, with or without weft threads which pass over and under the successive paired abutting shanks of adjacent elements. Even stronger bracing can be obtained with bulbous projections on the shanks and bights, and by extending the coupling elements the entire width of the tape-like unit, replacing all or part of the weft threads. Thus the shanks can extend transversely to the warp over a substantial part or all of the tape-like unit to form the exclusive weft over this part or the entire width of the tape.
