A fastening tape (4) is attached to a molded item (2) such as a seat cushion with a face of gripping hooks (5) turned outwardly to hold a seat cover (3) having complementary fastening member thereon. The tape (4) is molded into the seat cushion (2) during the molding process. Since a liquid molding substance is used, the hooks (5) on the tape (4) are covered with a thin plastic film (17) which prevents the molding liquid from contaminating and clogging the hooks (5). In one embodiment, the film (17) has a relatively low disintegration temperature whereby the heat applied to the mold to cure the cushion (2) disintegrates the film (17) after the cushion has cured, leaving the exposed hooks (5) unclogged and ready for use. In another embodiment, film (17) has a relatively high disintegration temperature and is removed in a separate step subsequent to the molding process by additional heat, such as an open flame.

In a fastening member of the type characterized by having a base carrying on one side numerous rows of hook-like projections for mating, releasable engagement with a loose, fibrous non-woven patch to form a fastener assembly, the improvement which comprises a temporary thin protective film covering and sealingly enclosing the hook-like projections around the entire periphery of the fastening member against leakage of molding liquid past the film onto the hook-like projections to protect the hook-like projections from clogging by a molding liquid when molding the fastening member into a molded article and being removable from covering relation to the hook-like projections after the molding liquid has solidified, whereby the hook-like projections are substantially clear of clogging by solidified foam material at the end of the molding process and ready to receive the non-woven patch without an intermediate step of cleaning solidified foam material from the hook-like projections.
