Abstract
The calender disclosed comprises a vertical stack of linked rolls, which are driven individually by controlled electric motors. The control acts on the distribution of the supplied power to the individual rolls in such a way that the forces which act on the rolls in the horizontal direction, and are measured in the roll bearings, are minimized. This allows the use of slimmer rolls.
