ABSTRACT:
The invention relates to a print unit cylinder for rotary presses, the cylinder having a narrow non-printing gap for accommodating the rubber blanket or pressplate ends, the gap running parallel to the axis of the cylinder, and also an elastomeric filler element for bridging the non-printing gap opening to thus prevent a sudden change of the roll characteristic when two interacting cylinders roll over the cylinder gaps.
