Abstract
To suppress shocks from being transferred to the walls of a cylinder (3) of a printing machine, when grooves (7) on the cylinder roll-off against another cylinder, and particularly against the edges of another groove (8) in an engaging cylinder, a damping mass (11) is filled within the cylinder which additionally retains an elastic shaft (12) on which an inertia mass (13) is secured. The inertia mass, preferably in form of a ball, is excentrally located on the elastic shaft (12) and touches at a point C the inner surface of the wall (10) of the cylinder (3) when the cylinder is in engagement with another one. The impact or shock, at the edge of the groove (7) rolls off against an engagement cylinder causes the inertia mass (13) to be accelerated towards the center of the cylinder, typically upwardly, and to place this mass into oscillations. These oscillations are damped by the damping mass (11) thus preventing transfer of oscillatory bending movement to the wall of the cylinder, and hence to a covering ( 5) thereon, which, for example, may be a printing rubber blanket, a printing plate, or the like.
