<p>A method and apparatus for forming a web wherein a fiber suspension from a head box is fed on a section of a forming wire formed by a first, substantially horizontal dewatering zone, and where the web being formed is thereafter led to a second dewatering zone where an upper wire is caused to cover said web, and both wires together with the web between them are led over a deflecting member. In the twin wire dewatering zone the wires bent upwards. After the turning member the web runs further linearly between the wires obliquely upwards. The web and the lower wire run around a pick up suction roll and the upper wire leaves the web. The dewatering in the dewatering zones occurs only in one direction, i.e. through the forming wire.</p> |
