ABSTRACT:
A method and apparatus for positioning and indexing molded hollow plastic articles for trimming molded hollow plastic articles having flash and a finish for a closure wherein the articles are supported and moved in succession by a vacuum conveyor which holds the articles in upright position and moves them past successive stations for deflashing, facing, inspection, rejection and unloading. The conveyor is a chain slat conveyor having longitudinally spaced vertical holes that communicate with a vacuum chamber over which the conveyor is trained. The conveyor is driven intermittently and moves the articles in succession past each of the stations. At the load station, the articles are oriented so that they are in proper alignment and relationship to the openings in the conveyor.
