ABSTRACT:
A separable slide fastener comprises a pair of warp-knit stringer tapes each having a pair of webs which are interconnected by connector threads extending across the tape to provide a series of spaced openings receptive of stitching threads for attaching the fastener to a fabric article. A pair of rows of coupling elements is mounted on opposite longitudinal edges of the stringer tapes and taken into and out of inter-digitating engagement by a slider movable along the rows of coupling elements. The stringer tapes have at one end thereof a separable bottom end stop. A reinforcement strip preferably made of a textile material is mounted on each of the stringer tapes adjacent to the separable bottom end stop. The reinforcement strip has a series of pre-formed apertures spaced at such intervals and of such a size which are suitable for receiving threads from a knitting machine and a linking machine as well to secure the fastener to the fabric article.
