Abstract

The invention concerns a method for damping vibrations in rolls of a roll pair that forms a nip. In the method the nip is run fixed and has a desired linear pressure in such a way that the load created by the loading arrangements of the roll pair 101, 103 is stabilized at a controlled level. When the desired linear running pressure is achieved and the load created by said load devices is stabilized, the bearing housings 102, 104 of rolls 101, 103 is coupled in the roll pair rigidly relative to each other in such a way that the mutual movement of the bearing housings 102, 104 is prevented. Bearing housings 102, 104 are connected to each other so that the coupling can be opened if necessary. The invention also concerns an arrangement for performing the method. <IMAGE>
