ABSTRACT:
An automatic machine-plate change system 20 of the web-offset printing press 10 has new-plate cassettes 30U, 30L provided in a priming press 11 having plate cylinders 13U, 13L to accommodate new-plates 80U, 80L newly wound around the plate cylinders 13U, 13L, and has movement systems 40U, 40L moving the new-plate cassettes 30U, 30L to cause edges 32U, 32L of the new-plate cassettes 30U, 30L to move toward and away from the plate cylinders. Therefore, it is possible to actualize an automatic machine-plate change with a simple structure and a simple operation, to quickly and efficiently change the machine-plates, to reduce the cost of facilities and to actualize the automatic machine-plate change in high certainty and reliability. As for a more concrete structure of the movement systems 40U, 40L, for example, it is possible to provide pendulum systems 41U, 41L causing the new-plate cassettes 30U, 30L to pivot at the fulcrum around the other edges 33U, 33L opposite to the edges 32U, 32L to move the edges 32U, 32L toward and away from the plate cylinders 13U, 13L, and shifting mechanisms 42U, 42L causing the new-plate cassettes 30U, 30L to shift along the axis in the direction of the axis of the plate cylinders 13 U, 13 L.
