Device for mounting a printing plate on a plate cylinder for a rotary printing press

An arrangement comprising:

• a plate cylinder having a rotational axis and adapted for use in a rotary printing press, the plate cylinder having a cylinder jacket and a recess followed by a clamping channel which extend at least approximately parallel to the rotational axis of the plate cylinder inside the cylinder jacket;
• a printing plate having a leading end and a trailing end, as seen in the rotational direction of the printing cylinder, which are both secured inside the recess, the printing plate having a trailing end region that includes two parallel bent edges extending transverse to the rotational direction of the plate cylinder, one of the bent edges formed by a section of printing plate which fits against the cylinder jacket of the plate cylinder and another section of the printing plate that projects into the clamping channel and enclosing an approximately right angle, the other of the bent edges being formed by the section of printing plate which projects into the clamping channel and an end section of the printing plate which extends through the clamping channel;
• and
• an ejection element arranged inside the clamping channel which is operative to eject the trailing end region of the printing plate from the clamping channel.
