Abstract: An apparatus for changing a plate cylinder in a web-fed rotary gravure press comprises supporting mechanisms for detachably supporting both ends of a plate cylinder, a palette for carrying the plate cylinder, an elevator having a first conveying mechanism for conveying the palette in an axial direction of the plate cylinder and being vertically movable between a first position where the plate cylinder is supported by the supporting mechanism and a second position where the plate cylinder is conveyed in the axial direction by the conveying mechanism, and a truck movable in a direction perpendicular to the axial direction of the plate cylinder and having a pair of second conveying mechanisms parallel to each other for conveying the palette in the axial direction of the plate cylinder when the elevator is at the second position.

Abstract: An automatic cleaning apparatus for a gravure plate cylinder comprises a carriage having a spatula capable of contacting the outer cylindrical surface of a gravure plate cylinder and a solvent sprinkling pipe for sprinkling a cleaning solvent on the outer cylindrical surface of the gravure plate cylinder which is rotated about its axis during the cleaning operation. The carriage is moved in a direction parallel to the gravure plate cylinder by rotating a screw bar, and the spatula of the carriage is pressed against the gravure plate cylinder by a pressure shaft connected to an actuator.
