<p>A woven zipper has two cooperating zipper sections each having an elongated zipper tape provided with a longitudinally extending margin and an elongated flexible element which extends along this margin. A filament extends in an undulate path along the margin and forms a plurality of successive loops each having one leg passing in front of and another leg passing behind the flexible element. A first curved connecting portion extends outwardly of the margin and element and connects one leg of each loop with an adjacent leg of a successive loop, and a second curved connecting portion extends inwardly of the margin and element and connects the legs of each loop to one another. A coupling projection is formed on each first connecting portion for engagement with a cooperating projection of the adjacent zipper section. First threads extend along the element adjacent the second connecting portions and are located exclusively in front of the legs, and second threads also extend along the element adjacent the second connecting portions but are located exclusively behind the legs. First weft thread portions are woven into the zipper tape at longitudinally spaced locations and each extends transversely of the second threads and crosses the element in front of the latter, and second weft thread portions are also woven into the zipper tape, each being located intermediate two of the first weft thread portions and extending transversely of the first threads and crossing the element behind the latter.</p> |
