Abstract
A fastener assembly of the type for being molded into cushions, and including a base having first and second major surfaces defining first and second opposed ends and first and second opposed side edges. Hooks are carried by the base cooperating with complementary loops carried on material when pressed against the attachment members on the base. Permanent anchors are carried by the base and are spaced apart sufficiently to allow foam intrusion between the anchors to attach the fastener assembly to a foamed article, such as, for example, a cushion. First and second magnetically-attractable side edge seals are attached to the base for being attracted to magnets positioned in a mold in which the cushion is molded. The side edge seals form a foam-tight seal between the side edges of the base and the mold to prevent intrusion of liquid foam during molding of the article. First and second magnetically-attractable end seals are attached to the base for being attracted to magnets positioned in the mold in which the cushion is molded to form a foam-tight seal between the ends of the base and the mold to prevent intrusion of liquid foam onto the hooks during molding of the article. Each of t…
