Abstract
The invention relates to a device with an interchangeable leaf for holding a printing plate on a plate cylinder in a rotary printing press, and to a tool for dismantling the leaf. A leaf for fastening an edge of a printing plate onto the external surface of a plate cylinder penetrates into the latter via a slit and is mounted against a flat of a tension bar housed in the plate cylinder through the use of a passage receiving a end region of the leaf, of stop means for retaining the end region in the passage counter to movements other than the movement for extraction via the slit, and an elastic stop piece locking the end region by elastic clipping counter to such a movement but capable of being actuated by means of a flat tool inserted via the slit to release the end region. The mounting and dismantling of the leaf may thus be performed through the slit, without extracting the tension bar.
