    摘要： A method and apparatus of producing a fastener product having a multiplicity of fastening members with stems integrally molded with a strip-form base, along with a product and a preform product so produced. Molten resin is applied to a rotating mold roll having an outer surface for forming one side of the base, and a multiplicity of cavities extending inward from the outer surface for molding the stems. A preform product is stripped from the mold roll having a multiplicity of upstanding, preform stems extending from a side of the base. The preform product is passed through a post-forming nip between a heading roll and a backing member to form overhanging heads at the distal ends of the upstanding stems. The heading roll has a multiplicity of cavities about its periphery for forming the heads. Various means are disclosed for aligning the preform stems and the heading roll cavities. In another embodiment, a dimpled, heated heading roll is employed to post-form the stems to form fastener elements that extend in random directions.

    摘要： A touch fastener strip includes a sheet-form material substrate having a front face, an array of fastener elements integrally molded with a resin base layer on the front face of the substrate and an array of discrete regions of resin (e.g., gripping elements) integrally molded with a resin base layer through apertures in the sheet-form material on the back face of the substrate. The array of fastener elements forms a discrete band of fastener elements extending longitudinally along the front face of the fastener strip, and the array of gripping elements forms a discrete band of gripping elements extending longitudinally along the back face of the fastener strip.

    摘要： A molded area fastener product, such as a self-engaging fastener, has a strip-form base of resin with a broad surface from which an array of discrete fastener elements extends. The fastener elements each include a molded stem extending from the broad surface of the base to a curved head that extends toward a front side of the fastener element, forms a crook and ends in a distal tip. In some examples the curved head protrudes beyond the stem on the back side of the fastener element to form an overhang defined by an overhang surface of the head directed toward the base, and the crook is defined in part by an underside head surface that overhangs a lower portion of the stem. In some examples the fastener elements are arranged to provide a high distension overlap when mated with an identical fastener product.

    摘要： A male fastener element extends integrally from a planar base and includes a primary engagement hook and a secondary engagement structure (e.g., a hook). The primary engagement hook has a stem portion that is integrally molded with the planar base and that extends from the planar base to a distal end. The primary engagement hook also has an overhang portion that extends from the distal end of the stem portion and that has an underside surface overhanging an open volume for receiving loops. The secondary engagement structure, which is shorter than the primary engagement hook, is disposed immediately adjacent the primary engagement hook and extends from a side surface of the primary engagement hook. The secondary engagement structure extends from the base to a distal end that is disposed, in side view, below the underside surface of the overhang portion of the primary engagement hook.

    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.
