<p>A fastener product (60, 60', 130) includes a longitudinally extending strip-form base (12, 106) and a plurality of longitudinally discrete regions (14, 170) of fastener element stems (18, 18'). Each discrete region includes a thermoplastic resin layer (62, 108) bonded to a second base material (70, 70', 100) by an intermingling of the resin of the resin layer (62, 108) with the second base material and the fastener element stems (18 18') are molded, integral extensions of the resin (32) from the resin layer (62, 108). Each longitudinally discrete region (14, 170) is surrounded by an area (13, 114) of the strip-form base (12, 106) that is free of the fastener element stems (18, 18'). Various methods of making such a fastener product (60, 60', 130) and others, include introducing various barrier (60, 60', 80, 90, 102) and backing materials (100) into the molding gap (34) to limit the fastener element stem (18, 18') formation and/or the lamination of the resin to the barrier and/or backing material during the molding process.</p> |
