ABSTRACT:
A calender includes a roll stack that has two end rolls and at least one intermediary roll, wherein the end rolls each have a deflection compensation device that acts in the direction of the intermediary roll. At least one end roll has an additional deflection compensation device that acts in the direction away from the intermediary roll. On the side of the at least one end roll which is remote from the intermediary roll is disposed a supplementary roll. This calender is able to carry out a matte satination operation without being fixed as to roll-specific pressures, which pressures must be of a precise magnitude so as to compensate for the deflection of the intermediary rolls.
