Abstract
A printing machine, preferably a flexographic printing machine, is provided with at least one counter-pressure cylinder and with at least one printing roller and one engraved roller, whose one end floats in the frame. To intercept the free ends of the printing roller and the engraved roller during the printing operation, the bearing blocks, in which the journals of the free ends of the printing and engraved rollers are supported in the slid-in state, can be moved in guides at right angles to the printing and engraved rollers in the frame.
