    摘要: Twin wire former and method for manufacturing a fibrous material web from a fibrous suspension using same. The twin wire former comprises a movable bottom wire belt and a movable top wire belt converging at a twin wire zone. The twin wire zone has a first section, a second section and an end section. A rotating forming roller is disposed at the first section of the twin wire zone, and the to wire and the bottom wire form a wedge-shaped inlet gap at the first section of the twin wire zone. The inlet gap is adapted to receive the fibrous suspension from a headbox. The bottom wire belt and the top wire belt are adapted to form the fibrous web therebetween at the second section of the twin wire zone, and the second section of the twin wire zone has at least one drainage element. A separating device is disposed at the end of the twin wire zone and is adapted to separate one wire belt from another the wire belt. The twin wire zone has a section disposed in a steep downward direction downstream of the forming roller in relation to the movement of the wires. Also disclosed is a method for manufacturing a fibrous material web from a fibrous suspension using a twin wire former.
