Abstract: A woven slide fastener stringer includes an edge portion woven of foundation warp threads and a single foundation weft thread which is laid in a series of pairs of weft picks. A row of filamentary coupling elements is disposed against one side of the longitudinal edge portion with two pairs of picks provided for each coupling element, one pair at each side of the adjacent leg. A binding warp thread system has threads which engage the upper legs remotely from the edge portion and which extend downwardly to pass beneath one or two pairs of weft thread. By this arrangement, the coupling elements are stably secured in position.
