Abstract
A can bodymaker and a method of forming different sizes of drawn and wall ironed cans from the same bodymaker, in which the bodymaker includes a ram (), a crank (), first and second connecting rods () and a swing lever () connecting the crankshaft () to the ram (). Different locking positions (X, Z) are provided on the swing lever so that the first (primary) connecting rod is connected to alternative positions on the swing lever. The primary connecting rod () then rotates about an axis between the selected locking position and position (Y) of pivot pinon the swing lever (). The primary connecting rod drives the swing lever to rotate by a corresponding degree, and thereby converts the swing lever rotation into axial movement of the ram () so as to move the ram by a specific stroke length. By altering the locking pin () position and therefore the pivot point for the primary connecting rod, the stroke of the ram is changed.
