ABSTRACT:
To suppress bending oscillations, particularly when tensioning or blanket attachment grooves of operating cylinders of a rotary printing machine, specifically of an offset printing machine, are engaged with each other, bearings (4) are supported by tensioning bars (3), one end of which is pressed by a stop (17) or a cam (5) towards the bearing, the other being tensioned by a spring (7) or hydraulic (40-44) arrangement thereagainst. The cam can be released from pressing position upon receiving a "stop print" command. Alternatively, rather than pressing the ends of the pressure bar (3) against fixed portions, for example the side walls (18, 28) of the machine, two adjacent cylinders can be pressed against each other by connecting the respective ends of the pressure bars together, one of the connections preferably including a releasable, for example hydraulic pressure loaded joint (23) and the other having the spring or fluid pressure tensioning force applied thereto.
