发明名称 Forming fastener products
摘要 A method and apparatus for forming a fastener product are disclosed. The method comprises molding a preform member in a mold cavity defined by first and second parts of a mold, removing the first part of the mold to expose an array of preform elements of the preform member while the member remains within the second part of the mold, and, while holding the member by the second part of the mold, performing a subsequent forming operation on the preform elements. The apparatus deforms the preform elements, preferably with a heated mold plate, to form fastener elements while holding the member by the second part of the mold. In a preferred embodiment the resulting elements are mushroom-shaped and the preform is held in the second part of the mold by another fastening feature. Both reciprocating and rotary-type machines are disclosed.
