ABSTRACT:
Apparatus for removing tail flash from molded plastic articles, such as containers or bottles, in which a pair of reciprocatory jaw assemblies are formed with meshing teeth which engage the flash from opposite sides and subsequently tear the flash from the article. The jaw assemblies are formed with meshing tooth-like projections which engage flash from opposite sides at spaced locations along the line of juncture between the web of flash and the surface of the article. Inclined cam surfaces on one jaw assembly urge a flash web engaged between the teeth of the closing jaws outwardly away from the article to tear the flash clear of the article.
