Abstract (en)
[origin: EP1314821A2] The calender (1) to polish the surface of a paper/cardboard web (2) has a number of press nips (6,7) in the web path through the assembly, each formed between a roller surface and counter surfaces. The counter surfaces are formed by rotating flexible mantle (4,5), pressed against the roller surface by press shoes (8,11), to form the two wide press nips at the same roller (3). One press nip (6) has a heater (15) to give a heated nip and the second press nip (7), in the direction (14) of web travel, has a cooling unit (22) to give a cold nip. The heater and the cooler act on the roller surface.
