Abstract
In a concealed woven slide fastener stringer, a fastener tape is woven of foundation warp yarns and a double-pick foundation weft yarn, and a coiled fastener element is attached to folded inner margin of the tape by anchoring warp yarns and a double-pick anchoring weft yarn with coupling heads facing inwardly and connecting portions facing outwardly. The foundation weft yarn is interlaced with the outer one of two core cords inserted through the fastener element. The anchoring warp yarns cross the foundation weft yarn between the successive legs; one of the anchoring warp yarns is disposed between the coupling heads and the inner core cord, and two of the anchoring warp yarns are disposed between the core cords. The anchoring weft yarn is interlaced at one end with the outer anchoring warp yarn and at the other end with the foundation weft yarn crossing the inner anchoring warp yarn, thereby fixing the fastener element firmly.
