Abstract
The calender (1) has a pressure producing unit (6) for producing a preset pressure in a nip (3). A web treatment unit (7) includes two contact surfaces (9, 10) that form a treatment gap (8). The surface (9) is formed by a band (14) that circulates at guide rollers (11-13). The surface (10) is formed by a circulating outer wall of a heatable roller (4). The band exhibits a flexible thickness region at a side facing a paper or cardboard web (2), where the thickness region exhibits a spring rate smaller than a spring rate of the web to start treatment in the treatment gap.
