Abstract
A printing machine designed to accommodate different repeat lengths for a first and second cylinders, that includes: a front and rear frames; a first cylinder cartridge, including a first cylinder with a centerline; a first assembly attached to the front and rear frames for holding the first cylinder cartridge; a second cylinder cartridge separate from the first cylinder cartridge, with the second cylinder cartridge including a second cylinder with a centerline; a first and second cradles for holding the ends of the second cylinder cartridge, with the cradles including a cradle arm with an opening therein; and a second assembly for each cradle for moving its respective cradle to hold different diameter second cylinders in parallel adjacency with the first cylinder. The second assembly is specifically designed to be operable to change the orientation of its respective cradle for each different diameter second cylinder to facilitate lift-off. In a preferred embodiment, this change in orientation is performed during the movement of the cradle that brings the second cylinder into parallel adjacency with the first cylinder. It is also preferred that the orientation of the cradles be suc…
