ABSTRACT:
Calender having a frame having a roll stack therein and a lower deflection control roll as the lowermost roll of the roll stack. The lower deflection roll has a sleeve supported on a bracket having opposed ends. The lower deflection control roll further has a deflection control device configured to secure the bracket against rotation. The deflection control device is further configured to operate in the direction of a center place of the roll stack. The calender further has a pair of bearing blocks, each bearing block being configured to hold a respective end of the bracket. Each bearing block is adjustable by a respective loading device. The calender further includes a pair of pivoted arms each having a proximal end and a distal end, the proximal end swivelly connected to the frame, and the distal end connected to a respective bearing block. The calender also has a correction device having a guide element adapted to move along a guideway, the correction device adapted to adjust at least one of the bearing blocks. The operational direction of the deflection control device remains substantially constant when at least one of the bearing blocks are adjusted by the correction device. Also provided is a method of operating a calender. The method includes adjusting, via the connection device, the bearing block, and maintaining the operational direction of the deflection control device substantially constant.
