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.

A flexible circuit has a roll-molded thermoplastic resin base sheet with an integrally molded mounting structure located to receive a light emitting diode device in an illuminating position. The mounting structure is a pin receptacle constructed to receive a pin of the light emitting diode device. An electrically conductive portion is carried by the resin base and positioned for electric connection to conductors of the device. Another flexible circuit carries discrete integrated circuit chips and a field of fastener elements extending from a surface of a resin strip carrying conductive traces interconnecting the chips.

A method of forming a flexible conductive strip includes: molding a continuous, flexible base of an electrically insulating thermoplastic resin, while forming channels in a surface of the base; at least partially filling the formed channels with a flowable, electrically conductive composition; and then stabilizing the flowable composition in the channels to form a pattern of stable, electrically conductive traces within the channels. A method of forming a flexible circuit board having loop-engageable touch fastener elements includes: molding a continuous, flexible base from an electrically insulating thermoplastic resin, while forming a field of stems integrally molded with and extending from a first side of the base; applying a conductive material to the base to form a pattern of electrically conductive traces in accordance with a circuit design; and forming loop-engageable heads on the stems.

Touch fastener components include a sheet-form base and an array of touch fastener elements on an engaging side of the sheet-form base. Each touch fastener element includes a stem extending outwardly from the sheet-form base and an engageable head extending from a distal end of the stem. The touch fastener components carry indicia, e.g., molded indicia, on a surface thereof, the indicia including features smaller than the touch fastener elements and visible from the engaging side of the sheet-form base.

The invention relates to fastener molding. In one aspect, a molding apparatus for forming a sheet-form fastener product includes a first ring defining a plurality of voids extending inwardly from a circumferential surface of the ring. The voids are circumferentially spaced apart from one another by portions of the ring including recessed regions that partially define molding cavities. The molding apparatus also includes multiple plug members configured to be disposed within the voids. The plug members and the portions of the ring therebetween cooperate to define the molding cavities when the plug members are disposed within the voids. The molding cavities are shaped to mold, from molten resin forced into the molding cavities from a peripheral surface of the molding apparatus, an array of fastener elements having overhanging heads for releasable engagement with a mating fastener product.
