Abstract: A printing unit having a tucker bar capable of tucking a tail edge of a printing plate into an axially-extending gap of a plate cylinder and a tucker bar control device for automatically moving the tucker bar from an operating position to a non-operating position so as to permit access to the axially-extending gap. In addition, a method of plating a plate cylinder using such a tucker bar control device to automatically move the tucker bar so as to permit access to the axially-extending gap of the plate cylinder.

Abstract: In a rotary printing press, an apparatus for adjusting the lateral and circumferential position of the plate cylinder is provided. The apparatus includes a sleeve having an inner surface with threads disposed thereon; a shaft disposed within the sleeve, and connected to the machine element such that when the shaft moves laterally the machine element is moved laterally, the shaft having an outer surface with threads disposed thereon which engage the threads disposed on the inner surface of the shaft; a gear assembly coupled to the sleeve, such that a rotational movement of the sleeve causes a circumferential movement of the machine element; a first drive for rotating the shaft, such that when the shaft is rotated, the shaft moves the machine element laterally; and a second drive for rotating the sleeve, such that when the sleeve is rotated, the sleeve moves the gear, and the gear rotates the machine element circumferentially.
