Abstract
A bodymaker tool pack including a plurality interleaved ironing and spacer rings through which a ram or punch forces a workpiece to redraw a metal can body. Hydrostatic pads are created between the punch and spacer rings to effectively guide the punch through the tool pack. Additionally, the ironing and spacer rings are themselves supported by hydrostatic pressure pads formed within the tool pack housing.
