Abstract
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.

A method of making a fastener assembly comprising a plurality of individual fasteners joined together by a string, each of the fasteners comprising a female member having a longitudinal opening, a male member insertable and lockable into the opening of said female member, and a string member formed from a portion of the string and connecting together said male and female members with a distance therebetween, wherein the longitudinal axis of said string member is perpendicular to the longitudinal axis of the opening in said female member, the method comprising the steps of: A. placing a string through a female-member forming mold, said female-member forming mold comprising an upper mold portion and a lower mold portion, said lower mold portion having splittable segments, in such a manner that said string extends linearly along a line substantially tangential to the opening of the female member to be formed, and then joining said upper mold portion and lower mold portion together; B. thereafter raising one of said splittable segments of said lower mold portion; C. then, while maintaining said one of said splittable mold segments in the raised position, charging a molten thermoplastic resin into said mold cavity thereby molding the female member of the fastener, and then releasing the formed female member out of the mold by moving the upper mold portion away from the lower mold portion and further raising said raised one of said splittable mold segments of the lower mold portion; D. placing the string through a male-member forming mold disposed adjacent to said female-member forming mold, the male-member forming mold comprising an upper mold piece and a lower mold piece, the string being disposed so as to extend across the mold cavity defined between said upper and lower mold pieces when assembled; then joining said upper mold piece and said lower mold piece together, followed by charging molten thermoplastic resin into said mold cavity, thereby forming a male member engageable with the female member formed through the above steps A to C, and thereafter releasing the formed male member by separating said upper mold piece and said lower mold piece of said male-member forming mold; and E. thereafter, taking-up a first portion of the string on a roll, then operating a next cycle of molding of the female member and the male member on the string by the above steps A to D, and repeating this operation cycle to produce a length of the string having a number of pairs of the female member and the male member formed in series thereon.
