摘要

The rear fixing rail (4.2) is in work connection with an eccentric (18.2) and is pivotable around a rotary point in a long guide (28). A central fixing rail (12) is movable in the peripheral direction of the plate cylinder (1). The eccentric has an element (18) with counter-running pitches and connected to an operating device (24). This element is a wedge rail (18.1) with eccentrics formed as inclined surfaces. Alternatively, it can be a shaft with eccentrics applied zone-wise in the form of an arithmetical spiral. USE/ADVANTAGE - For accurate and rapid fixing of a flexible printing plate in a sheet rotation offset printing machine.
