| 摘要 |
<p>The invention relates to a method and apparatus for cutting the edge of a fibre web (4) in a paper machine. In the method, water nozzles (13a, 13b) are conducted in a transverse direction with respect to the edge of the fibre web (4) so that the place where the cut comes against the surface of the yankee cylinder of the drying unit varies. The apparatus comprises water nozzles (13a, 13b) used for cutting, pipes (14a, 14b), a base (16), and a pneumatic cylinder (17) by which the water nozzles (13a, 13b) are deflected both in a longitudinal and transverse direction with respect to the fibre web (4).</p> |
