<p>A slide fastener comprising two rows of interdigitable coupling elements each row being formed by a respective synthetic resin monofilament, wherein each coupling element of each row has an eye-shaped coupling head adapted to be received between the heads of the other row, a pair of connecting shanks extending away from the coupling head, and a respective bight joining each shank to a shank of a respective adjacent coupling element, each row of coupling elements being held by longitudinal textile threads in a respective tape-like support structure with the coupling heads projecting laterally along an edge of the support structure, each coupling head lying in a plane substantially perpendicular to the plane of the respective tape-like support structure; the shanks of each coupling element lying in a plane parallel to the plane of the slide-fastener beyond transition regions at which the shanks join the respective coupling head; the shanks of each coupling element extending away from said transition regions laterally and directly abutting one another in the plane which is parallel to the slide-fastener plane; the longitudinal textile threads forming transverse pockets each receiving a respective one of said pairs of shanks; and the respective bights extending out of each pocket into adjacent ones of said pockets.</p> |
