Abstract (en)
[origin: EP2270280A1] The calendar (1) has a nip (3) formed between a heatable roller (4) and a counter element (5). A pressure generation device (6) generates a preset pressure in the nip. A web treatment device (7) has a revolving contact surface (9) formed by a band (14) rotating around guide rollers (11-13). Another contact surface (10) is formed by an outer wall of the heatable roller, where the contact surfaces form a treatment gap (8). The band has an elastic surface that presses a paper or cardboard web against the heatable roller. The guide rollers control belt tension forces of the band in the gap.
