摘要:
A fastener product includes a base; and an array of fastener projections extending integrally from a first surface of the base, the projections each including a stem portion of resin molded integrally with the first surface of the base, and a head portion disposed at a distal end of the stem portion and configured to releasably engage a complementary fastener element to form a fastening; wherein the stem portions of the fastener projections and at least a portion of the base are integrally formed of a single resin; and wherein at least a portion of the single resin of the base is in a foamed state.
摘要:
A method of forming a fastener is provided, including (a) forming, from a thermoformable material, a preform product having a sheet-form base and an array of preform stems integrally molded with and extending from the base to corresponding terminal ends; (b) heating the terminal ends of the stems to a predetermined softening temperature, while maintaining the sheet-form base and a lower portion of each stem at a temperature lower than the softening temperature; and (c) contacting the terminal ends with a contact surface that is at a predetermined forming temperature, lower than the softening temperature, to deform the terminal ends to form heads therefrom that overhang the sheet-form base. Fasteners and other methods of forming them are also provided.

Fastener products and related methods are disclosed. In some embodiments, the fastener products include an elongate strap defining an aperture and a row of projections extending from the elongate strap. A portion of the elongate strap including one or more of the projections can be passed through the aperture to retain the fastener product in a fastened state.

An electrical cable includes first and second conductive strips and an electrically insulative base extending between and joining the first and second conductive strips and electrically isolating the first conductive strip from the second conductive strip. The first and second conductive strips each include an electrically conductive thermoplastic resin in contact with a longitudinally continuous electrical conductor, the electrically conductive thermoplastic resin having a lower electrical conductivity than the electrical conductor. The electrically conductive thermoplastic resin forms an exposed surface of the cable and a field of fastener elements extending from the exposed surface. Lighting systems and electrical fastening devices include similar features.

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 skin-friendly hook component of a hook and loop fastener that reduces or eliminates the occurrence of red-marking and/or irritation if brought into contact with a wearer's skin. In one embodiment, the hook component can have a relatively large top surface area among the hooks with respect to a surface area of the hook backing. In another embodiment, the hook backing is highly flexible, attributable to a flexible resin and/or modified topography. In yet another embodiment, a highly flexible polymer, or polymers, can be used to make individual hooks such that the hooks bend in response to a minimum amount of pressure. Various illustrated hook tapes have features along their edges to enhance skin-friendliness. A skin-friendly hook component results any combination of the disclosed embodiments. The hook component is particularly beneficial when used in absorbent articles.

A fastening tape has a sheet-form base carrying an array of hooking members (10,22,24,34) each having a height (h) of about 0.008 inch (0.2 millimeter) or less, as measured from the base, and fiber-engaging features, such as re-entrant tips (18,32), disposed less than about 0.003 inch (0.08 millimeter) from their upper surfaces, as measured normal to the base. Such hooking members are employed to releasably engage directly into foams and fine denier non-woven materials, such as those of insulation, filters, construction moisture barriers, disposable gowns and diapers.
摘要:
A method for producing a multiplicity of fastener element molding cavities extending from a mold surface, for molding a plastic product having fastener elements integrally molded with and extending from a product base, and a mold so produced. The mold cavities are formed by depositing multiple layers of plating material on a workpiece in a predetermined pattern selected to produce a desired mold cavity shape, or by depositing a thick stratum of plating material over an array of fastener elements and then removing the fastener elements to leave shaped cavities within the plating material. The mold may be in the form of a roll or belt for continuous processing, or in any form for discrete injection molding. Molds having fastener element cavities defined by rigid cast materials are also disclosed.
