ABSTRACT:
This invention relates to a method for producing a fibrous web from at least one fibrous suspension in a twin mesh former with a twin mesh zone which has a wedge-shaped intake nip and is formed at least in some sections by two rotating endless meshes, of which the first mesh, which is passed over a preferably positionable inlet roller, is passed in the double mesh zone over several rails rigidly arranged a distance from each other on a preferably movable dewatering box, and of which the second mesh is passed in the twin mesh zone over several rails which are arranged opposite the rails of the preferably movable dewatering box, are supported by way of compliant elements and are pressed with a selectable force against the second mesh. The method further provides that in the region of an adjustable intersection point in which the first mesh intersects at a preferably adjustable intersection angle with the fibrous suspension lying on the second mesh, a locally acting dewatering pulse is introduced by way of the second mesh into the fibrous suspension. In addition, the invention relates to a twin mesh former of a machine for producing a fibrous web, in particular a paper web or paperboard web, from at least one fibrous suspension, and to a sheet forming system of a machine for producing a preferably multi-layer fibrous web, in particular a paper web or paperboard web, from at least one fibrous suspension.
