    • 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.
    • 本发明涉及紧固件成型。 一方面,用于形成片状紧固件产品的成型设备包括限定从环的圆周表面向内延伸的多个空隙的第一环。 空隙通过环的部分周向间隔开,包括部分地限定模腔的凹陷区域。 成型装置还包括被配置为设置在空隙内的多个插塞构件。 当插塞构件设置在空隙内时,插塞构件和它们之间的环的部分配合以限定模制腔。 模制腔被成型为从模制设备的外围表面强制进入模制腔的熔融树脂成形为具有用于与配合紧固件产品可释放接合的悬伸头的紧固件元件阵列。
