ABSTRACT:
A method and device for drainage of a fibrous suspension where a converging drainage gap is formed between a first area and a second area. At least one of the first area or the second area is water permeable. A curved drainage zone is connected to the converging drainage gap. The first area moves relative to the second area. A fibrous suspension is introduced into the converging drainage gap. The fibrous suspension is transported by one of the first area and the second area as a layer. The first area and the second area are compressed closer together thereby causing drainage from the fibrous suspension through one of the first area or the second area.
