ABSTRACT:
The invention relates to a twin wire former (1) for producing a fibrous web (4), in particular a paper, cardboard or tissue web, from a fibrous suspension according to the generic terms of claim 1. The twin wire former (1) is characterized in that, the two wire belts (2, 3) run upwards after a passing a first deviation device (10), forming an angle (β) relative to an imaginary second horizontal plane (H2), in such a way that the upper vertex (15.SO) of the second deviation device (15) lies above the lower vertex (10.SU) of the first deviation device (10), and that the angle (δ) relative to the imaginary first plane (H1) runs downwards.
