Abstract

Die Erfindung betrifft ein Bahnleitelement zur Führung und/oder Umlenkung einer laufenden Papier-, Karton- oder anderen Faserstoffbahn, welches mit Druckgas beaufschlagbar ist und sich im Wesentlichen über die gesamte Breite der Faserstoffbahn (3) erstreckt, aufweisend einen Mantel (2) mit einer der Faserstoffbahn (3) zugeordneten Bahnleitfläche (2a) und wenigstens einer gasdurchlässigen, porösen Schicht, um zwischen der Bahnleitfläche (2a) und der darüber laufenden Faserstoffbahn (3) einen Tragfilm zu bilden.
Erfindungsgemäß ist vorgesehen, dass der Mantel (2) aus einer inneren (4) und einer äußeren Schicht (5) besteht, wobei die äußere Schicht (5) aus dem gasdurchlässigen, porösen Material besteht, welches einen Widerstand gegen das den Mantel (2) durchströmende Druckgas () bildet und wobei die innere Schicht (4) stabilitätsbildend ist und eine Vielzahl an Durchtrittsöffnungen (13) aufweist, die in Verbindung stehen mit wenigstens einer Druckkammer (7) für die Beaufschlagung mit dem Druckgas.

The invention relates to a web guide for guiding and / or deflecting a running paper, cardboard or other fibrous web, which is acted upon with compressed gas and extends substantially over the entire width of the fibrous web (3), comprising a jacket (2) with a the fibrous web (3) associated Bahnleitfläche (2a) and at least one gas-permeable, porous layer in order to form a support film between the Bahnleitfläche (2a) and the overlying fibrous web (3).
According to the invention, the jacket (2) consists of an inner (4) and an outer layer (5), wherein the outer layer (5) consists of the gas-permeable, porous material which provides a resistance against the jacket (2). and wherein the inner layer (4) is stability-forming and has a plurality of passage openings (13) which are in communication with at least one pressure chamber (7) for the application of the pressurized gas.
