| abstract |
A fastener of the hook and loop type intended to incorporated into plastic articles by plastic molding processes is formed of a known separable fastener member having a base member and a plurality of engaging elements upstanding from one surface thereof. A vinyl plastisol, thermoplastic, or rubber encasement which intimately surrounds at least some of the individual engaging elements protects the elements when they are exposed to the harsh environment of a molding process. The fastener is placed in a mold and molded into, as an integral part thereof, a plastic part. The encasement is removable from the engaging elements after the molding process, to expose the engaging elements, without permanently deforming or substantially destroying the fastening performance thereof. |
