Abstract

A printing unit for a web fed rotary printing machine is provided including a machine frame support, two sets of printing unit cylinders, carriages, drive motors and guide elements. The two sets of printing unit cylinders, include a plurality of outer printing unit cylinders and a plurality of inner printing unit cylinders. Each carriage corresponds to one printing unit cylinder for rotatably mounting its corresponding printing unit cylinder on the machine frame support. There is a drive motor for each carriage. Two sets of guide elements are arranged on the machine frame for determining a travel setting of the plurality of carriages along the machine frame support. The guide elements for the outer cylinders are arranged on the frame support in an orientation different than the guide elements for the inner cylinders so that movement of the outer printing unit cylinders is in a different direction than movement of the inner printing unit cylinders. Optionally, the printing unit accommodates additional printing devices that are moveable in relation to their corresponding cylinders and vice versa.
