Abstract (en)
[origin: EP1314819A2] The calender (1), to polish a paper web, has a nip (11) between a heated roller (3) and a rotating flexible mantle (5), which is pressed against a given surface segment of the heated roller by a support (7). An additional heated metal belt (15) is passed through the nip, to give a surface polishing zone between the belt and the roller, and to pass through the nip between the web (2) and the rotating mantle. The belt heater (16) is in front of the nip. A cooling unit (23) acts on the rotating mantle, after the nip.
