ABSTRACT:
A separable slide fastener comprises a pair of warp-knit stringer tapes each having a pair of webs with a wale-free region therebetween, which are interconnected by a connector thread extending across the wale-free region at longitudinal intervals, the wale-free region being receptive of a chain of thread loops for attaching the stringer tape to a fabric. A pair of rows of coupling elements is mounted on opposite longitudinal edges of the stringer tapes and taken into and out of interdigitating 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 member is mounted on each of the stringer tapes at the one end thereof and connected to the separable bottom end stop. The reinforcement member extends between the tape webs across the wale-free region and includes a roughened surface such as teeth adjacent to the wale-free region for engagement with an end of the chain of thread loops on the reinforcement member against displacement thereof.
