Abstract: A printing press has a replaceable cassette removably mounted on a frame. An impression cylinder cooperates with a printing cylinder in the cassette to define a nip through which sheet material moves during printing on the sheet material. The impression cylinder is movable relative to the frame between a retracted position in which the impression cylinder is offset to one side of the cassette and a printing position in which the impression cylinder extends into the cassette. In addition, a manually actuatable mechanism is provided to simultaneously adjust the size of opposite ends of a gap at the nip between the printing cylinder and the impression cylinder.

Abstract: A transfer cart (10) facilitates exchange of printing cassettes in a printing press (14), the printing cassettes have respective images to be printed. A first shelf (70) of the transfer cart (10) receives a replacement printing cassette (12b) from a cassette storage facility (16). The transfer cart (10) has a base (60) with wheels (62) such that the transfer cart can be moved from the storage facility (16) to a location adjacent to the printing press (14). A second shelf (74) of the transfer cart (10) receives a replaceable printing cassette (12a) from the printing press (14) while the replacement cassette (12b) is retained on the first shelf (70).
