An adapted separable fastener and method of making the same for attachment to foam objects such as seat cushions. A separable fastener member of the hook and loop-type is attached, in back-to-back relation, to a second member. The second member has upstanding elements such as loops or hooking elements which elements are ultimately surrounded and encapsulated by the foam during polymerization. The adapted fastener is thereby attached to the foam member. The elements are positioned in order to allow venting of the gaseous byproducts of polymerization. This promotes superior adhesion to the foam material and prevents delamination at the fastener-foam interface. A metal strip may be disposed within the adapted fastener so it may be magnetically held in the foam mold. A method and apparatus for adapting the fastener is also disclosed.

An adapted separable fastener for attachment to a foam plastic article comprising: (a) a separable fastener member having a base member and a plurality of one portion of engaging elements upstanding from one surface thereof; (b) a second member attached to said separable fastener member in back to back engaged relation on the side of said separable fastener member opposite the side having said plurality of upstanding engaging elements; and (c) a plurality of generally parallel spaced apart non-overlapping rows of individual spaced apart non-overlapping monofilamentary loop elements upstanding from the surface of said second member opposite the surface in engagement with said separable fastener member, said spaced apart monofilamentary loop elements each defined by two leg portions each attached at one end to said base member and connected to each other at the other end by a connecting portion which completes said loop each of said spaced apart rows being sufficiently spaced from all adjacent rows and each said loop element being so dimensioned and spaced with respect to adjacent loop elements that they may be substantially completely surrounded and encapsulated by foam plastic material which forms at least part of said foam plastic article thereby firmly attaching said separable fastener member to said foam plastic article without the existence of delaminated portions or trapped gases formed during foaming.
