<p>An injection molded elongated article (16) having a head (18) and a strap (20), such as a cable tie, is ejected from between separated first and second mold parts (10, 12) by imparting a forceful gaseous stream (46, 58, 66) between the mold parts to thereby peel a first portion (42) of the strap from the first mold part after a second portion (44) of the strap adjacent the head of the article was peeled from the first mold part by ejecting the head of the article from the first mold part while retaining the first portion of the strap in the first mold part. In a multi-cavity injection molding apparatus, a pair of nozzles (36, 52, 62) are contained within each of a plurality of components (34, 50, 60) through which compressed air flows into the region between the mold parts; and the nozzles are disposed closely adjacent the heads of a pair of cable ties for imparting a pair of gaseous streams from the component for peeling the first portions of the straps from the first mold part. In one embodiment, the nozzle-containing component (50) is disposed within both the first mold part and the second mold part while the mold is closed and is at least partially disposed in the space between the first and second mold parts when the mold is open; and one of the mold parts includes a recess (56) for receiving while the mold is closed the portion of the component that is at least partially disposed between the first and second mold parts when the mold is open. <IMAGE></p> |
