Abstract (en)
The edge strip (3) is removed before the web (1) is transferred to the belt (8) which carries it on. The strip is separated using a water jet, during support by the belt (2). The strip (3) is released using an air and/or water jet. This is directed at the belt (2) from a nozzle (6) on the opposite side of the belt (2). The belt is air- and water-permeable. The edge strip is scraped (5) from the belt and led off. The strip is carried away using a removal channel or tube (12) using suction and/or water flushing, into a pulper. Further variants in accordance with these principles are presented. Salient features include a ceramic strip associated with the air nozzle, which contacts the belt. The belt (2) is a forming sieve. During removal of the web from the belt (2), the transfer belt employed, wraps a suction guide roller (9). A strip is removed from each side of the web. An independent claim is included for corresponding equipment.
