Adjustable transfer assembly for container manufacturing process

摘要

A transfer turret assembly is provided for transferring can bodies between process stations in a can necking machine. The transfer turret assembly includes a rotatable transfer starwheel. A plurality of pockets is formed in the starwheel that can each receive a can body. The turret assembly includes a vacuum assembly having a first zone that is under vacuum and a second zone separated from the first region by a boundary.
