| Zusammenfassung: | 1. Field of the invention.
In a method and apparatus for damping contact oscillations of rotating rolls in a paper machine, but notably in a coater, the rolls are held endways in bearings. At least two rolls form a nip with each other. The damping is carried out actively and the active stimulation (phase-shifted counteroscillation) acts from outside directly and/or indirectly on at least one bearing point of one of the rolls. |
