ABSTRACT:
A slide fastener comprises two continuous plastic filaments, each with a multiplicity of helicoidal coupling elements for interlocking with the elements of the opposite filament, each filament being woven integral with the threads of its respective support tape to form a single tape-like unit. Each coupling element has a coupling head on a loop end and a long shank and a short shank extending from opposite sides of the loop end. The long shank terminates in a first bight portion connecting it with a long shank of one adjacent coupling element, while the short shank terminates in a second bight portion connecting it with a short shank of another adjacent coupling element. The coupling elements are arranged in rows of mirror-image pairs, each including two long shanks and two short shanks. Warp threads are interwoven with the coupling elements, with even stronger bracing possible with bulbous projections on the long shanks, short shanks, first bight portions or second bight portions using textile weft threads.
