Abstract

Die Erfindung betrifft eine Vorrichtung zur Entwässerung einer Materialbahn, insbesondere einer Papier- oder Kartonbahn, durch Austreiben von Wasser aus der Materialbahn mittels Gasdruck, mit zumindest einem von wenigstens vier parallel angeordneten Walzen begrenzten Druckraum, in den ein Druckgas einleitbar und durch den die Materialbahn hindurchführbar ist, wobei die Positionen der Walzen relativ zueinander verstellbar sind.

The invention relates to a device for dewatering a material web, in particular a paper or cardboard web, by expelling water from the material web by means of gas pressure, with at least one pressure space limited by at least four rollers arranged in parallel, into which a compressed gas can be introduced and through which the material web can be passed is, the positions of the rollers are adjustable relative to each other.
