Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zum schwebenden Führen von Warenbahnen mittels eines gasför­ migen oder flüssigen Mediums. Die Vorrichtung besteht aus einem oder mehreren in Materialbahnlaufrichtung und quer dazu hintereinander angeordneten länglichen Strömungskör­ pern mit konvex zur Materialbahn 1 gewölbter Oberfläche und mit Abstand zu dieser Oberfläche und in Reihe derart angeord­ neten Düsen 11a, 11b, daß die aus den Düsen austretenden Freistrahlen 15, 16 die Oberfläche des Strömungskörpers 10 unter spitzem Winkel anblasen und sich an der Oberfläche in Wandstrahlen umwandeln, bevor sie insbesondere durch Strö­ mungsumkehr die Materialbahn 1 anblasen. Besonders bei beiden Längsrändern eines jeden Strömungskörpers zugeord­ neten Düsen mit gegeneinander gerichteten Freistrahlen er­ gibt sich ein gegenüber herkömmlichen, nach dem Tragflä­ chenprinzip oder Luftkissenprinzip arbeitenden Vorrichtungen ein verbessertes Tragverhalten mit stark progressiver Kennli­ nie im Nahbereich der Materialbahn und verhältnismäßig stei­ lem Einlauf in den Nullwert der Tragkraft. The invention relates to a device for suspended guiding of material webs by means of a gas conveyor medium or liquid medium. The device consists of one or more in the direction of the web and across for this purpose arranged elongated flow bodies core with convex surface to the material web 1 and at a distance from this surface and arranged in such a row neten nozzles 11a, 11b that the emerging from the nozzles Open jets 15, 16 the surface of the flow body 10 Blow at an acute angle and in on the surface Convert wall beams before they are particularly affected by currents Blow on the material web 1. Especially at assigned to both longitudinal edges of each flow body neten nozzles with opposing free jets gives itself compared to conventional, after the wing Chen principle or air cushion principle working devices an improved wearing behavior with strongly progressive characteristics never close to the material web and relatively stiff lem entry into the zero value of the load capacity.
