The invention relates to a method and device for guiding a paper web, or corresponding web-like moving track, by using jets of compressed air as an aid. There are two jet directions, one essentially facing the arrival direction of the web (1) and the other essentially facing the departure direction of the web (1), in which case the jets form an area of vacuum between them. Compressed air is fed from one or more inlet ducts (3, 6).
La présente invention concerne un procédé et un dispositif destinés à guider un papier en bobines, ou un rail de déplacement de type bobine correspondant, à l'aide de jets d'air comprimé. Il existe deux directions de jet, l'une faisant sensiblement face à la direction d'arrivée de la bobine (1) et l'autre faisant sensiblement face à la direction de départ de la bobine (1), auquel cas les jets forment une zone de vide entre elles. L'air comprimé est admis par un ou plusieurs conduits d'admission (3, 6).
