Some conventional printing cylinders include therein a damping system having springs which receive oscillation forces transmitted from the cylinder wall, for example by cross bars, disks, or the like, to dampen oscillations occurring upon roll-off of an axial clamping groove formed in the cylinder against an engagement cylinder. To reduce not only bending and torsional oscillations, but also the effect of the impact shock when the groove rolls off against the engagement cylinder, impact positions are defined within the cylinder against which either the damping springs or elements coupled to the damping springs can engage the cylinder upon deflection thereof due to the impact shock so that the resulting elastic shock or impact is likewise transferred to the damping springs of the damping system. The damping system includes oscillation transferring rods, bars, or the like which may be embedded or at least in part contacted by elastic materials, such as foam or the like.
