Abstract:
A damping system for corrugated cardboad fabrication rollers, which has a damping device included inside a roller to counteract vibrations of the roller, wherein said damping device is fixedly mounted to a wall of said roller and comprises:two spaced-apart coaxial jackets which define a space therebetween, each jacket having two ends, and a closing ring located at each of the corresponding ends of said jackets; damping bushings loosely situated in said space and grease located in said space between said damping bushings; a tubular axis extending axially through said damping device; friction masses incorporated on said tubular axis; elastic washers pressing said friction masses; and corresponding nuts to said elastic washers which allow regulation of tightness so as to adjust damping.
