Abstract

Improved arrangement of woven web for zip fasteners, characterized in that it comprises a strip formed with warp and weft yarns and consisting of a band section defining a larger dimension of said web and a woven filament section defining a part longitudinal marginal of said tape; a row of successively interconnected elongated loops incorporated externally in said filament section each of said loops having a coupling head at one end an upper arm and a lower arm extending from said head in a common direction and a bead portion remote from said head connected to the adjacent next loop of said successive loops; a first warp system extending parallel in longitudinal direction of said belt and above the upper arms of successive loops of said elongated loops and a longitudinal warp yarn extending longitudinally of said belts below the upper arms of said loops; and a second linking warp system consisting of a plurality of outer warp yarns extending parallel and longitudinally of said tape below the lower loops of successive loops of said loops and an internal warp yarn extending longitudinally. Of said ribbon above the lower arms of said loops, said first and second warp knitting systems being interwoven in the spaces between each by adjacent said loops with the parts of said basic weft yarn that are inserted in double passes in said section of woven filament.
