F 7059 (14-158) COMMON WIRE PATH OF A WET END SECTION OF A TWIN WIRE PAPER MAKING MACHINE ABSTRACT OF THE DISCLOSURES The invention relates to a wet end section of a twin wire paper machine. Each wire forms a wire loop. The wires are led together along a vertical, rising, common path, which starts at a wedge shaped face nip at the bottom of the common path. The nip is formed by the two wires and is defined by a forming cylinder arranged in the loop of the inner wire. In side the other outer wire, there is a fixed curved sur- face or outer surface having a center of curvature which lies on one side of the rising common wire path. A further curved inner surface which follows the outer surface along the wire path is provided on a pivotable crossbeam located inside the loop of the inner wire. This is followed by a suction roll arranged in the loop of the outer wire. The length of the further inner surface is shorter than the length of the outer sur- face.
