Abstract

Die Erfindung betrifft ein Verfahren in einem Zylindertrockner einer Papiermaschine, in dem die Papierbahn an den Oberzylindern unter Verwendung eines Obersiebes und an den Unterzylindern unter Verwendung eines Untersiebes geführt wird, wobei die Siebe von den Trockenzylindern und in deren Zwischenräumen angeordneten Leitwalzen geführt werden, derart, daß die Bahn an der Oberzylinderreihe vom Obersieb in direkten Trocknungskontakt mit der Oberfläche der Oberzylinder und entsprechend vom Untersieb gegen die Oberfläche der Unterzylinder gepreßt wird und die Bahn von einer Zylinderreihe zur anderen über eine bestimmte Strecke als freier Zug geführt wird, wobei Luft eingeblasen wird. Sie ist voprnehmlich dadurch gekennzeichnet, daß die Luft, insbesondere erhitzte Frischluft direkt in die vom Trockensieb und der Papierbahn gebildeten Taschen eingeblasen wird. Weiters betrifft die Erfindung eine Vorrichtung die für einen Zylindertrockner einer Papiermaschine mit einer Zweisiebführung vorgesehen ist, der eine Lufteinblaseinrichtung aufweist. Die Vorrichtung ist gekennzeichnet dadurch, daß die Lufteinblaseinrichtung (18, 19, 20, 21), insbesondere ein Lufteinblasrohr, in der vom Trockensieb (8, 9) und der Papierbahn (7) gebildeten Tasche (22, 23, 24, 25) vorgesehen ist.
