Description
Die Hülse kann sich über die gesamte mit Austrittsöffnungen versehene Länge des Mantels erstrecken; in diesem Fall erlaubt die Verwendung einer aus einer Mehrzahl unterschiedlicher Hülsen mit jeweils anders angeordneten von Durchgangsöffnungen freien Bereichen auszuwählenden Hülse die Anpassung des Austrittsbereichs an die Breite einer umzulenkenden Materialbahn. Denkbar ist aber auch, Hülsen zu verwenden, die sich nur über einen Teil der Länge des Mantels erstrecken, und die zu mehreren nebeneinander angeordnet werden, um den gesamten mit Durchgangsöffnungen versehenen Bereich des Mantels zu überdecken. Durch Verwendung von Hülsen mit zu den Austrittsöffnungen kongruent verteilten Durchgangsöffnungen einerseits und von Hülsen ohne Durchgangsöffnungen andererseits ist es möglich, die Breite des an der Oberfläche der Umlenkstange erzeugbaren Luftkissens an die Breite der umzulenkenden Materialbahn anzupassen.
