Abstract
The invention refers to a process for dewatering a pulp web, particularly a chemical pulp web, where dewatering takes place between twin wire belts or felts in an initial dewatering zone with a set area pressure and then in a second dewatering zone. It is mainly characterized by the area pressure in the initial dewatering zone being pre-set, and in the second dewatering zone it is adjustable, with the web being dewatered in both directions (upwards and downwards). The invention also refers to a device for implementing the process.
