Abstract

See full text

An elongate fastener assembly comprising a flexible polymeric backing strip from which project a multiplicity of headed stems adapted to engage loops on materials pressed against the heads, and an open porous permanent attachment layer attached to the surface of the backing strip opposite the stems which has sufficient open area to receive foam to permanently attach the fastener assembly to a foamed article. The fastener assembly has a temporary attachment layer comprising granular ferromagnetic material in a polymeric binder sandwiched between the backing strip and the permanent attachment layer which is adapted to be attracted by magnets to temporarily hold the fastener assembly in position during a foaming process, and has a heat shrinkable film cover means overlaying the heads attached to the edges of the backing strip that will shrink transversely to expose the heads upon the application of heat below 125.degree. C.
