Abstract
A bodymaker includes a totaling crankshaft including an offset crank, the adjustable eccentric assembly including an eccentric shell assembly. The eccentric shell assembly is operatively coupled to the crankshaft crank. A primary connection rod is operatively coupled to the eccentric shell assembly. A ram assembly is operatively coupled to the primary connection rod. The ram assembly includes an elongated ram. In this configuration, the ram reciprocates over a stroke that is a function of the orientation of the eccentric shell assembly. Further, in an exemplary embodiment, the ram assembly is structured to adjust the range of the ram body stroke through a die pack without substantially decoupling a number of substantial components.
