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.
A method for securing a fastening member to an article to be molded, said fastening member having a base carrying numerous hook-like projections for mating, releasable engagement with a complementary fastener to form a fastener assembly, said method comprising the steps of:
A method for securing a fastening member to an article to be molded, said fastening member having a base carrying numerous hook-like projections for mating, releasable engagement with a complementary fastener to form a fastener assembly, said method comprising the steps of:
In a fastening member having a base carrying on one side numerous hook-like projections, the improvement which comprises a temporary thin protective film positioned over said hook-like projections and sealingly enclosing the hook-like projections around the entire periphery of the fastening member while said fastening member is being molded into a molded article, said film protecting said hook-like projections against clogging by the molding liquid and being removable from covering relation to the hook-like projections after the molding liquid has solidified.
In a fastening member having a base carrying on one side numerous hook-like projections for mating, releasable engagement with a complementary fastener to form a fastener assembly, the improvement which comprises:
