Abstract (en)
[origin: WO2021170278A1] The invention relates to a method and a device for drying a pulp web (1), comprising press-dewatering and conveying of the pulp web (1) directly on the press sleeve (4) to a first transfer region (5) for delivering the pulp web (1) onto a transfer clothing (6), and delivering the pulp web (1) in a second transfer region (7) onto a drying cylinder (8). The invention is characterised in that the pulp web (1) is thermally dried between the first transfer region (5) and the second transfer region (7). This allows the production of a pulp web (1) which has improved quality properties with simultaneously low consumption of energy.
