To provide a new method for drying paper/paperboard web by pressing in a processing apparatus.
In the method, the processing apparatus includes a belt 2 adapted to extend around a guiding element 3, at least one counter element 5 being disposed on the outside of the belt 2 to provide a contact area with the belt 2, and the belt 2 and the counter element 5 establish therebetween a web processing zone for passing a web W to be processed therethrough. In the method, pore volume are formed on both sides of the web W, the pore volume on at least one side of the web W is formed in a compressible felt/wire and carried, the volume is compressed and the felt/wire is compressed, and at the same time the gas pressure in the pore is increased and as the result a gas flow which is directed to the web W is generated, and water penetration toward the other side pore volume of the web W is produced.
