A fastening member of the type characterized by having a base carrying on one side thereof gripping fastener hooks for mating connection with complementary gripping fastener fibrous patches. A protective cover engages the base for enclosing the hooks against leakage of molding liquid past the film onto the hooks to protect the hooks against clogging by a molding liquid when molding the fastening member into a molded article in a mold. In the improvement according to the invention, a flexible, granular ferromagnetic attachment strip is provided, and is positioned in overlying relation on top of the hooks. The attachment strip extends along the length of the fastening member within the area enclosed by the temporary thin protective film for being attracted to a magnet in the mold. The ferromagnetic attachment strip temporarily holds the fastening member by magnetic attraction in the mold during the molding process.
In a fastening member characterized by having a base carrying on one side thereof a first part of a gripping fastening member for mating connection with a complementary second part of a gripping fastening member, and a temporary cover engaging the base for protecting the first gripping fastener part against leakage of molding liquid past the temporary cover onto the first gripping fastener part to protect the first gripping fastener part against clogging by a molding liquid when molding the fastening member into a molded article in a mold, the temporary cover comprising a flexible, granular ferromagnetic attachment strip positioned in overlying relation on top of the first gripping fastener part and extending along the length of the fastening member for being attracted to a magnet in the mold to temporarily hold the fastening member by magnetic attraction in the mold during the molding process, and a tab carried on the end of the cover for permitting the cover to be easily and quickly removed by gripping and pulling the cover free of said first gripping fastener part the after the molding operation is completed.
