Abstract
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.
