Abstract (en)

[origin: EP0854233A2] To dampen the oscillations of rollers in contact with each other, especially in a paper web coating assembly, an active damping action is generated as a phase displaced counter oscillation. It is applied directly or indirectly, externally, on at least one roller bearing mounting. Also claimed is a roller assembly with at least two rollers pressed together, to form a nip between them, with each roller supported on bearing mountings at their end sides. One of the rollers, forming the nip, can be given a swing movement. Actuators (10-12) apply an external active action through a phase displaced counter oscillation, directly and/or indirectly on at least one bearing mounting (7) of a roller (1,2).
