Abstract
This printing press includes a frame and at least one plate cylinder which extends along a longitudinal axis and which is mounted so as to rotate on the frame in order to be able to rotate about the longitudinal axis thereof. The press includes at least one actuator and the plate cylinder includes at least one plate locking bar which extends within the plate cylinder. At least one portion of the bar can be moved under the action of the actuator between an extracted position for locking and a retracted position for unlocking a plate on the plate cylinder. The actuator is carried by the frame.

A printing press comprising:
- a frame;
- at least one plate cylinder extending along a longitudinal axis and rotatably mounted on the frame with respect to the longitudinal axis;
- at least one actuator supported by the frame;
- and
- a roller supported by the frame;
- the plate cylinder including at least one plate locking bar extending within the plate cylinder and a driving arm rotatably driving at least one portion of the plate locking bar,
- the actuator moving the at least one portion between an extracted position for locking and a retracted position for unlocking a plate on the at least one plate cylinder,
- the driving arm being rotationally fixed to the at least one portion and operatable with the actuator via the roller,
- the actuator moving the roller between a position abutting the driving arm and a position disengaging the driving arm.
