ABSTRACT:
A method and device for cutting a paper web (9) in a twin wire former (1) is described, said web being formed between two forming fabrics (4, 5) while wrapping a section of a forming roll (3), and the web cutting being carried out with the aid of jet cutters (10, 11) discharging jets of pressure medium so that a paper web of final width is obtained and, when applicable, a tail in the web. The jet cutters (10, 11) are arranged at the forming roll (3) so that the web cutting is carried out in the web at a point where the recently formed paper web (9) and the forming fabrics (4, 5) together wrap said section of the forming roll (3) in a sandwich structure.
