Abstract
A process is provided for operating a calender roll including a roll jacket surrounding an inner chamber. The process includes creating an active oscillation in the inner chamber that acts upon the roll jacket. By creating an oscillation within the calender roll, the appearance of undesired bar rings, which form on the external surface of the roll jacket due to operational exciting forces, is avoided. Furthermore, calender roll is provided including a roll jacket surrounding an inner chamber, and at least one actuator provided within said inner chamber acting upon said roll jacket.
