摘要：A process and apparatus for removing water from a mechanical pulp, chemical pulp or paper sheet, carried between top and bottom wires running through a dewatering machine having a first dewatering zone. The apparatus includes at least one suction box positioned downstream of the first dewatering zone. The process includes generating an air current in at least one of the wires downstream of the first dewatering zone with the suction box. The air current removes water from the wire and directs it into an inner chamber of the suction box. The invention also refers to a device for implementing the process.
