Abstract
To permit adjustment of the engagement pressure of mutually engaged roller elements, such as bearer rings (1, 3) or rubber blanket cylinders (31-34) against an impression cylinder or plate cylinders (35-38), a blind bore (4) is formed in the respective roller elements in a zone where engagement pressure will result in deformation in a wall of the blind bore, the bore being filled with a fluid such as hydraulic fluid, silicone, or the like, the pressure of which is determined by a pressure transducer such as a piezoelectric element coupled, through an amplifier, to a peak detector which indicates pressure upon axial alignment of the blind bore (4) and the axes of rotation of the respective engaging rollers. A base pressure in the chamber can be adjusted by an outside adjustment screw which, like the transducer, is preferably carried on an external adapter element attached to the respective roller.
