Abstract
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.
