  • Patent number: 4198886
    Abstract: An apparatus for deflashing a plastic article is disclosed. In operation, an operator places the article having flash in a nest which positions the article so that the flash is in a horizontal plane. A powered shuttle assembly picks the article up from the nest and places it upon an anvil. The anvil has striking edges which follow the line of juncture between the article and the flash. A punch apparatus is lowered onto the article and strikes the flash at the line of juncture disjoining the flash from the article. The power shuttle then removes the article without the flash to a discharge point. Optionally, at the discharge point, there may be provided an orientation assembly wich orients the deflashed article so that it may be placed upon a conveyor belt which carries the article to a collection point.
