Abstract (en)
[origin: EP1048780A2] The press section, at a machine for the prodn. of a fiber paper or cardboard web, has press belts (8-11) which run separatel over guides (13) at the guide zones (12) at the opposite ends flanking the roller press gaps (6,7). The press belt angle (14) between the press belts (8-11) is ≥ 15 degrees . The fiber web (1) is supported by at least one press belt (8-11) at the press section. Pref. all the press belts (8-11) are press blankets. The belt guides (13) are rotating rollers with a radius pref. ≤ 0.8 m. At least one guide roller (13) is on a movab mounting. The press belt angle (14) is set by the position of a guide roller (13), pref. as a bisection of the belt angle round A belt guide zone (12) is in front of and after the roller press gaps (6,7). The guide zones (12) have a pref. length of ≥ 0. Both press belts (8-11) for at least one roller press gap (6,7) travel separately before and/or after the press gaps (6,7), with press belt angle (14) between them of ≥ 15 degrees and pref. at least partially ≥ 30 degrees . Where the press belts (8-11 move over each other, the belt (9) not in contact with the fiber web (1) has a unit (15) to remove a carried air layer on the si towards the web (1) pref. as a scraper, compressed air jet or a suction roller.
