A method for active damping of vibrations in an apparatus for processing a moving web, for performing of this method suitable device, as well as for use in this device suitable roller

In the method for active damping of vibrations in an apparatus for processing a moving web, in which the web interacts with the working circumference of at least one roller (6), the active damping is performed by a phase offset to the vibration in the axle or shaft (8) of the roll (6) introduced bending moments. The invention also relates to a roller for processing a moving web with a device for the active damping of vibrations of the roll, wherein the engagement portion of the device on the axle or shaft (8) of the roller (6) is located such that the device for active damping vibrations in anti-phase bending moments acting initiates in the axle or shaft (8) of the roller (6).
