Abstract
A fastener comprising a female member having an opening, a male member which is engageable in the opening of the female member and a string member joining the female and male members, and a fastener assembly comprising a plurality of such fasteners joined together. The female and male members are molded from a thermoplastic synthetic resin, and fused to the string member. The fastener or fastener assembly is made by a method comprising placing a string through a female member forming mold and a male member forming mold, supplying a molten thermoplastic resin into the molds to form a female member and a male member, removing the molded female and male members from the molds, moving the string forward, repeating the molding of a plurality of female and male members, and if appropriate, cutting the string between the female member of one fastener and the male member of another.
