Abstract: A printing press unit for a printing press system which has a main frame with an impression roller mounted for rotation on a first axis characterized by a sub-frame being mounted for pivotal movement around a second axis and supporting a printing cylinder which will be moved into contact with the web passing between the impression roll and the cylinder. The sub-frame can be laterally adjusted along the second axis and the second axis can be skewed as necessary for purposes of registration of the web during a printing process. For a rotogravure printing, the ink applicator and doctor blade holder are both releasably mounted on positoning assemblies which are provided on the sub-frame.

Abstract: A coupling for use in transmitting both rotational movement and axial forces from a drive shaft to a driven shaft such as a shaft of a gravure cylinder characterized by a pin member being secured on the axis of both hubs to maintain the spacing between the hubs as a flexible plate arrangement secured to the hubs allows annular misalignment between the axes of the two hubs. The coupling allows side register of the gravure cylinder to be adjusted by shifting the drive shaft in the gear box of the printing press.
