Abstract (en)
[origin: EP2270279A1] The calendar (1) has a roller stack with an upper end roller (4.1), a lower end roller (4.2) and intermediate rollers (5.1-5.4), where the upper end roller limits a working gap (3) of the stack based on guide of a paper web (2). The upper end roller is a hard, heatable roller with a diameter greater than a diameter of the hard, heatable intermediate rollers (5.2, 5.4). An outer wall of the upper end roller forms a contact surface (9) of a web treatment gap (8) arranged upstream of the working gap, and forms another contact surface (10) by a belt (14) circulating on guide rollers (11-13).
