Abstract: Damping system for corrugated cardboard fabrication rollers comprising the incorporation of a damping device in the vapour chamber (2) of the application roller (1), said device being mounted integral with respect to the wall of the corresponding roller (1) so that the vibrations affecting the roller (1) are transmitted to the device, the vibration of the incorporating device being opposed to the vibration of the roller (1) as a result of the action-reaction principle thereby damping the vibration of the roller (1).
