To suppress shocks and bending oscillations arising upon roll-off of grooves (7, 8) of printing or blanket cylinders (3, 4) the blanket cylinders are constructed as hollow elements within which an absorber rod (12) is located, secured by a transversely extending member (11). The absorber rod which has propeller-like vanes, buckets or extensions (8) secured to its ends, the transversely extending member, and if provided, inertia masses secured to the end portions of the absorber rod are all embedded within a damping material filling the interior of the cylinder. The damping masses can be formed with the radial projections, vanes, buckets or propeller-like extensions (18), all embedded within the damping mass.
