Abstract
Process and apparatus for damping vibrations in a machine for winding material webs, in which the apparatus includes at least two cylindrical bodies. The process includes positioning the at least two cylindrical bodies to roll on each other to form a nip, such that at least one of imbalance and out-of-roundness of either of the at least two cylindrical bodies form a system capable of vibration. The process further includes actively damping vibrational forces of the vibration system in at least one of the at least two cylindrical bodies by displacing an axis of rotation of the at least one of the at least two cylindrical bodies in accordance with a current one of a plurality of vibrational force measurements made per each rotation of the at least one of at least two cylindrical bodies and with additional energy fed from outside of the vibration system.
