DD153573A5 - ZIPPER WITH WOVEN WEAR AND WOVEN ZIP MEMBERS - Google Patents

Abstract

The invention relates to a zipper with woven closure members made of endless Kunststoffmonofilamentfaeden, wherein the Grundkettfaeden the Doppelschuesse of the fastener tape and the closure members comprise alternating and Doppelschuesse are arranged under and between the closure members. With the aim of increasing the kink resistance of the zipper, the elongation in the region of the upper edge of the closure members is reduced by the fact that the double shots in the area between the closure members are pulled up by binding warp threads in the area between the closure members. The Bindekettfaeden grip two adjacent closure members while they grasp the intervening double shot. Subsequently, they are woven into the fastener tape under the following fastener elements, while at least one other group of binding warp threads makes this weave repeat offset. Conveniently, the binding warp threads and the raised double shots fill the space between adjacent closure members.
