Abstract

In an assembly in a paper and cardboard machine in a twin-wire section comprising a lower wire (1) constituted of the wire (1) of a fourdrinier wire section, and an upper wire (2) which is guided on top of the lower wire (1) by means of a forming roll (3), around which the twin-wire section is curved within a predetermined sector ( alpha ). The twin-wire section situated after the forming roll (3) is provided with a guiding means (6) on the side of the lower wire (1), the twin-wire section being curved at said guiding means in an opposite direction compared with the curvature on the forming roll (3). The section between the roll (3) and the guiding means (6) is provided with one or several dewatering means (4) on the side of the lower wire (1). Within said section on the side of the upper wire (2) there is provided a dewatering means, to which is connected means for effecting suction causing dewatering.
