Abstract
At least one roll of the calender is heated and provided with heat insulating shields pivotably mounted on the sides of the calender and heat insulating end covers disposed at the ends of the rolls. A counter roll (controlled deflection roll) cooperates with the heated roll in the direction of its pressure or pressing action. The counter roll is provided with a cooling device (blower device) which is capable of being regulated in zones for cooling the surface of the counter roll.
