Abstract
Press for removing water, wherein the material to be treated is led together with a wire which is pervious to water through a press nip zone formed by opposite surfaces. The press comprises compressible means for transporting the material to be treated. This means runs through the press nip and comprises several compression chambers which open out against the wire pervious to water. The compression chambers are preferably made so that they expand towards the water transmitting wire or felt, e.g. like a truncated pyramid.
