Abstract of the Disclosure An elongate fastener assembly comprising an elongate 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 along both sides of the backing strip, which temporary attachment layer is adapted to be attracted by magnets to temporarily hold the fastener assembly in position during a foaming process and restrict the foam from contacting the headed stems.
