Abstract (en)
[origin: EP1318235A2] The calender (1) to polish the surface of a paper or cardboard web (2) has a nip (10) between two rollers where the web passes through. The nip is a wide nip between a roller (3) and a counter surface formed by a rotating mantle (4) and a support shoe (5). The roller is driven at a different speed from the rotary speed of the mantle. The roller rotates faster than the mantle and with a faster speed than the speed of web travel, and it is heated. The roller and the mantle have speed controls as a roller drive (14) and a mantle brake (15). The mantle has a higher friction coefficient against the web than the roller.
