Abstract
A woven slide fastener stringer which includes a row of coiled coupling elements woven into one longitudinal edge portion of a woven stringer tape with a stuffer cord and upper and lower core threads extending longitudinally through a space defined in the coupling elements. Foundation warp threads and a foundation weft thread laid in double picks cooperate with the upper core thread to weave upper legs in the longitudinal tape edge portion. Binding warp threads underlying lower legs and interlaced at appropriate positions with the foundation weft thread, and the lower core thread are interlaced with a binding weft thread laid in double picks to weave the lower legs into the longitudinal tape edge portion. The binding weft thread is thinner than the foundation weft thread and aligned in parallel juxtaposition with the foundation weft thread in a region of the stringer tape excluding the longitudinal tape edge portion. With this arrangement, the coupling elements can be firmly and stably secured to the longitudinal tape edge portion, and the stringer has a desired flexibility.
