1. A can bodymaker comprising:
a ram assembly;
a removable first tool pack module adapted for receiving a ram of the ram assembly to elongate can bodies; the first tool pack module consisting of a first tool pack frame, a plurality of first dies that require alignment relative to one another, a first redraw sleeve module including a first redraw sleeve, one or more first fixings adapted for enabling removable fixing of the first tool pack module to the can bodymaker in a datum position; the plurality of first dies supported by the first tool pack frame, each one of the plurality of first dies being alignable with respect to the first tool pack frame and with respect to other ones of the plurality of first dies when the first tool pack module is spaced apart from the can bodymaker,
a removable second tool pack module adapted for receiving the ram of the ram assembly to elongate can bodies; the second tool pack module consisting of a second tool pack frame, a plurality of second dies that require alignment relative to one another, a second redraw sleeve module including a second redraw sleeve, one or more second fixings adapted for enabling removable fixing of the second tool pack module to the can bodymaker in the datum position; the plurality of second dies supported by the second tool pack frame, each one of the plurality of second dies being alignable with respect to the second tool pack frame and with respect to other ones of the plurality of second dies when the second tool pack module is spaced apart from the can bodymaker,
wherein the first fixings and the second fixings are precision mounts, and
whereby the second tool pack module, having the plurality of second dies mutually pre-aligned, is adapted for replacing the first tool pack module, upon removal of the first tool pack module from the bodymaker, by positioning the second toolpack module in the datum position, thereby enabling assembly of the second tool pack module into the can bodymaker after alignment of the plurality of second dies relative to each other and to the second tool pack frame.
