1. A method for inserting separable fasteners of the hook and loop type into plastic parts comprising the steps of:
- (a) coating the fastener to cover and intimately surround and encase the engaging elements with a protective means of an elastomeric composition which protects against the pressure and temperature of molding;
(b) inserting the coated fastener into a mold containing means for holding the fastener;
(c) injecting the mold with molten plastic;
(d) opening the mold to remove the plastic part thus formed; and
(e) removing the protective coating from the fastener elements to render the elements ready to engage elements on the companion portion of the hook and loop fastener.

Abstract
A fastener of the hook and loop type intended to be 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 covering which intimately surrounds the individual engaging elements protects the elements when exposed to the harsh environment of a molding process. This protecting covering is removable from the fastener after the molding process to expose the engaging elements without substantially destroying the performance thereof.
