A compensation device (9) for vibrations of an angle variable in a
printing material processing machine (1) having an associated actuator
(6) which acts on the angle variable, the compensation device (9)
receiving a signal representative of the angle variable characteristic,
and the compensation device (9) generating an output signal for the
actuator (6) is disclosed. The compensation device (9) has at least one
filter (13) in the form of a transfer function or a sum of transfer
functions whose frequency parameters correspond to the vibration
frequencies to be compensated, through whose effect the output signal of
the compensation device (9) is obtained from the signal at at least one
of the discrete frequencies to be compensated.
