摘要： A printing press includes two opposite mounting walls formed with aligned horizontally extending openings in which two sliding seats are mounted slidably and respectively, a printing roller extending horizontally between the mounting walls and having a longitudinal axis and two opposite ends mounted rotatably and respectively to the sliding seats, a printing plate unit mounted securely on the printing roller, a first retaining assembly provided on one of the mounting walls for retaining releasably a first one of the sliding seats in a desired position in the respective opening, and a second retaining assembly provided on the other one of the mounting walls for retaining releasably a second one of the sliding seats in a desired position in the respective opening. The retaining assemblies are actuated simultaneously to cause longitudinal sliding movement of the sliding seats within the openings so as to result in movement of the longitudinal axis of the roller relative to the mounting walls in a direction parallel to the mounting walls. Actuation of the second retaining assembly without actuating the first retaining assembly causes longitudinal sliding movement of the second one of the sliding seats within the respective opening so as to vary an angle formed between the longitudinal axis of the printing roller and one of the mounting walls.
