Abstract
An apparatus and a method for changing printing plates in sheet-fed rotary printing presses include a plurality of printing units and plate cylinders being coupled to one another mechanically in the printing units during a printing operation. At the beginning of a plate change, the plate cylinders are coupled to one another mechanically and are driven jointly by a main drive motor. After an old printing plate has been conveyed out, each plate cylinder is decoupled from the common mechanical connection and is driven by a separate drive motor.
