Abstract
The system includes a device in association with one of the rollers for emitting a signal that is proportional to the periodic eccentricity of the roller, this value being greater than the actual eccentricity of the roller. Another device then changes or modifies the amplitude of the periodic signal so that it is virtually the same as the actual eccentricity of the roller. Finally, there is a device for switching in the changed or modified signal into a thickness control system.
