摘要： The invention relates to a twin wire former for the production of a fiber web specifically a paper, cardboard or tissue web, from a fiber suspension. The invention is characterized in that the rotating forming roll has an open volume and is a non-suction type; the rotating forming roll has a forming roll diameter of less than 1,400 mm; the rotating forming roll has a forming roll angle of wrap of less than 70°; a forming suction box is located immediately downstream from the rotating forming roll as viewed in direction of wire travel; and in the area of the wedge-shaped inlet nip, the fiber stock suspension has a stock density of between 0.4% and 2.0%, preferably between 0.6% and 1.5%. These characteristics result in an improved forming quality and web quality.
