<p>A releasable strap (10) of hook and loop material is formed by continuously introducing molten resin (44) to a gap (42) defined adjacent a rotating mold roll (22) having an array of fastener element cavities (20), to form a band of hooks (12) extending from one side of a strip-form base (15). The resin also extends over an edge region (46) of the mold roll devoid of fastener element cavities, extending along one side of the molding region (45) of the mold roll, to form an edge portion (15') of the strip-form base devoid of fastener elements. A loop material (50) is bonded to an opposite side of the strip-form base (15), such as by introducing the loop material to the resin in the gap (42), and the resulting product is cut across both the band of fastener elements and the edge portion (15') of the strip-form base, to form straps (10) having end portions devoid of fastener elements (12).</p> |
