ABSTRACT:
A calender for treating both sides of a web of paper includes a roller stack. A working nip is formed between the juncture of one hard roller and one soft roller. A changeover nip is formed between the juncture of two soft rollers. The roller stack has eight rollers. The two middle rollers form the changeover nip. One of the middle rollers is a deflection adjustment roller and has an upper support device which can be pressure loaded and a lower support device which also can be pressure loaded. The supporting force that is exerted on the jacket by the upper support device is greater than the supporting force that is exerted by the lower support device.
