<p>An adapted separable fastener and method of making the same for attachment to other objects such as seat cushions. A separable fastener member (16) of the hook and loop-type is attached, in back-to-back relation, to a substrate (18). The substrate member may either be of an absorbent type, or it may have a plurality of upstanding elements (30) which are ultimately surrounded and encapsulated by foam formed during polymerization. The adapted fastener is thereby attached to a foam member. The elements (30) are positioned in order to allow venting of the gaseous by-product of polymerization. A metallic strip (20) is interposed between the separable fastener member (16) and the substrate member (18) which allows the fastener member (16) to be magnetically held in the mold during the forming of foam objects to facilitate simultaneous forming of the object and attachment of the separable fastener member (16). An apparatus for ultrasonically attaching the separable fastener and the substrate is also disclosed.</p> |
