Abstract: A printing cylinder for a printing press, specifically a web-fed printing press, is disclosed. The printing cylinder having an outer surface and at least one lockup slot introduced into the outer surface to clamp at least one printing form or at least one rubber blanket on the printing cylinder. The entire outer surface of the printing cylinder, including the, or each, lockup slot is evenly coated autocatalytically with nickel and phosphorus.

Abstract: A device for repairing a cylinder in a printing machine while the cylinder is installed in the printing machine. The device includes a cross slide rail having a base body with longitudinal guides, a longitudinal support slidably mounted on the longitudinal guides, and a transverse support connected to the longitudinal support. The cross slide rail is removably mounted to side walls of the printing machine so as to be parallel to a longitudinal axis of the cylinder to be repaired. A pull spindle is rotatably mounted to the base body and operatively connected to the longitudinal support so that the rotation of the pull spindle moves the longitudinal support along the longitudinal guides of the base body. A tool holder is connected to the transverse support for carrying a tool for working the cylinder. A mechanism for driving the cylinder is also provided.
