Abstract: Apparatus for trimming cylindrical cans wherein each can is orbited about a central turret axis while being rotated about its longitudinal can axis is disclosed. The cans are successively mounted with vacuum onto a support mandrel located on a support shaft within each of plural cartridge assemblies mounted at circumferentially spaced intervals on a turret disk. The can is firmly secured to the mandrel by vacuum so that the open end portion of the can body projects between an outside circular cutting knife and an inside trimming edge disposed within the open end. As the cartridge orbits about the turret axis on the shaft axis, the inside trimming edge is radially displaced by camming action into contact with the open end portion of the can body and the outside cutting edge to generate cutting forces for trimming the portion.
