Abstract
Abstract An apparatus for attaching a pair of fastener elements onto a garment comprising a plunger reciprocably mounted in a bored head for movement along a path toward and away from a stationary die mounted on a table in opposite relation to the bored head, the plunger having a punch for coacting with the die to attach the pair of fastener elements onto the garment from opposite sides thereof, and first and second means mounted respectively on the bored head and on the die for releasably holding the fastener elements in the path in front of the punch and the die. The first means is actuatable by the punch for releasing the one element. The second means is responsive to coaction with the first means for releasing the other element.

An apparatus for attaching a pair of fastener elements onto a garment, comprising: (a) a frame having a table and a bored head; (b) a stationary die mounted on said table in opposite relation to said bored head; (c) a plunger reciprocable mounted in said bored head for movement along a path toward and away from said die having a plunger head supporting a punch for coaction with said die to attach the pair of fastener elements onto the garment from opposite sides thereof; (d) first means on said bored head for releasably holding one of the fastener elements in said path in front of said punch, said first means being adapted to be actuated by said punch for releasing said one fastener element, and including a substantially hollow cylindrical holder slidably mounted in said bored head in front of said plunger; (e) second means on said die for releasably holding the other fastener element in said path in front of said die, said second means being responsive to coaction with said holder for releasing the other fastener element; and (f) third means acting between said plunger head and said holder for frictionally retaining said holder on said third means so as to enable said holder to move along with said plunger head, said third means comprising a split bush made of an elastic metal and fitted loosely over said plunger head, said holder being compressively fitted over said split bush so as to be held on said split bush under the resilience of said split bush.
