Patent abstract
The invention concerns a calender which comprises a vertical stack of interlinked rollers driven individually by regulated electric motors. The regulation process acts on the distribution of the delivered power to the individual rollers such that the forces acting on the rollers in the horizontal direction and measured in the roller bearings are minimized, so enabling slimmer rollers to be used.
