A method for dewatering a fiber suspension in a twin-wire press is disclosed including feeding the fiber suspension to an inlet end of an elongated dewatering space, dewatering the fiber suspension during displacement of the endless lower and upper wires which form the elongated dewatering space by flowing filtrate through the endless lower and upper wires, collecting the filtrate in outlet boxes, and adjusting the pressure differential between the elongated dewatering space and each of the upper and lower outlet boxes by controlling the counter-pressure applied to the filtrate flow on both sides of the endless upper and lower wires directly adjacent the inlet end of the dewatering space. A twin-wire press is also disclosed therein. |
