Abstract

In order that the tension, particularly of large printing plates, and their automatic retensioning, may be regulated uniformly over the entire width without having an adverse effect on the final tensioning by means of tensioning screws (11), a tensioning lever (15, 16) is associated with each tensioning screw and is pivotally connected to a divided rear tensioning bar (4). The tensioning levers bear via lugs (17) on a pressure strip (9) movable in the cylinder gap, there being springs (12) acting on the free ends of the levers.
