Method for manufacturing a woven zipper half

Abstract

In a method of manufacturing a woven zipper half a woven strip is produced of warp threads and of at least one weft thread. The weft thread is picked in the form of double pick loops. A plastic monofilament is wound to form a row of closing member-forming windings having interlocking heads at one end and winding reversing portions at the other end, wherein the closing member row is positioned on the woven strip. Additional warp threads are positioned underneath the closing member row. During weaving, at least one main knit thread is guided in the upward direction through gaps between the windings to the upper side of the closing member row to form loops with loop heads. The loop heads of the at least one main knit thread at the upper side are interlocked by crocheting. The loop heads, after crocheting, form a mesh structure covering portions of the upper side of the closure member row and interlock the closure member row with the woven strip. Simultaneously to interlocking of the loop heads at the upper side, double pick loops of the loop-shaped main knit thread are formed and the double pick loops are interlaced during weaving with the additional warp threads, and, moreover, the main knit thread is used as a weft thread in the woven strip underneath the closing member row.
