Abstract: A can end trimmer has a main rotary support shaft with a radial turret plate. A plurality of self-contained cutter unit cartridge assemblies have radial head flanges directly connectable to one side of the turret plate with driven members in each cutter unit cartridge automatically engaging control members mounted on the turret plate for effecting movement of a transversely shiftable cutter knife into engagement with an axially fixed cutter knife for effecting rotation of both knives to trim the end from a can held in a vacuum chuck. A shim between the cutter unit cartridge and the turret plate cants the axes of the knife members with respect to the can by a very small amount normally less than 2.0 degrees to effect a smooth burr-free cut of the can end. Stripper pin means surrounds the can being cut which in turn surrounds the axially fixed knife with a reciprocating stripper plate on the pins being easily removed during replacement of the cutter cartridge unit.

Abstract: An automatic can coating and feed means includes indexed turret means having a plurality of can supporting means spaced about its periphery including a driven vacuum chuck and can engaging roller supporting cans engaged on their sides by a driven roller for rotation about the can axis; can infeed means adjacent the turret feeds a can into said can supporting means during dwell of the turret, automatically operable spray means adjacent the turret coats the can interior during the dwell of the turret; in a second embodiment the cans engage driven belts upstream of the spray station so that they are already rotating upon arrival at the spraying station with a unique star wheel feed effecting rapid feeding of cans to the turret to provide rapid operation of the entire device.
