A redraw assembly for a can bodymaker includes a frame and a hold down piston moveably coupled to the frame so as to be slidable with respect thereto. The hold down piston is structured to have a blank holder coupled thereto for engaging and securing a cup adjacent an opening of a die pack. The redraw assembly further includes a cam disk engaged with the hold down piston and moveably coupled to the frame so as to be readily rotatable about a rotation axis and a motor having an output shaft coupled to the cam disk. The motor is structured to selectively rotate the cam disk about the rotation axis. The hold down piston is movable among a first positioning and a second positioning dependent on the positioning of the cam disk.

A thermoforming apparatus is provided having a frame, a pair of opposed platens, a toggle shaft, a kinematic linkage, a form air manifold, and a pair of articulating bearing assemblies. The pair of opposed platens is carried by the frame each with a die, one die configured to engage an opposed face of another die across a heated sheet of thermoformable material in sealed relation there between. The toggle shaft is carried by the frame for rotation. The kinematic linkage is coupled between the toggle shaft and one of the dies. The form air manifold and a source of differential pressure is coupled with a die face on one of the dies. The pair of articulating bearing assemblies is carried by the frame and configured to support the at least one toggle shaft for translation towards and away from the another die and platen. A method is also provided.

A hydrostatic/hydrodynamic fluid bearing assembly for a can bodymaker is provided. The hydrostatic/hydrodynamic fluid bearing assembly is separate from the ram body. The outboard guide bearing assembly includes a carriage assembly and a number of elongated journals. The carriage assembly includes a ram coupling, a crank coupling, and body defining a number of journal passages. The ram body is coupled to a ram coupling. The crank coupling is structured to be coupled to a crank arm. Each journal extends through a carriage assembly body journal passage. In this configuration, the ram body may form a can body in a traditional manner, but fluid bearing assembly fluid is not applied to the ram body. Instead, the fluid bearing assembly fluid is applied to the journals.
