Abstract:
A roll assembly (10) for a fiber-web machine has at least at one end thereof, with a bearing assembly (20) with a bearing housing, which bearing housing (18) has a flexible and attenuating attachment arrangement by means of which the roll can be attached in a flexible and attenuating manner on the frame or foundation (22) of the fiber-web machine. A mass absorber (24) is arranged in conjunction with the bearing housing, whereby the damping of the vibration of the roll assembly is arranged by the cooperation of the bearing housing that is attached in a flexible and attenuating manner and the mass absorber (24) in conjunction therewith. The invention also relates to a method of attenuating the vibration of a roll of a fiber-web machine.
