Abstract (en)

[origin: DE10157688C1] Calender has a nip formed between a roller and a mantle belt moving around it. The belt is held by supports around a section of the roller circumference, and press the web against the roller surface. The roller is heated, and an auxiliary belt with thermal conductivity travels between the roller surface and the web through the nip. Calender (1) has a nip (5) formed between a roller (3) and a mantle belt (4) moving around it. The belt is held by supports (6) around a section of the roller circumference, and press the web against the roller surface. The roller is heated, and an auxiliary belt (8) with thermal conductivity travels between the roller surface and the web through the nip. On emerging from the nip, the hot auxiliary belt travels with the web and against it over a given path length (9). In the free travel path, a cooling unit (10) acts on the side of the hot auxiliary belt towards the roller.
