Abstract

Die Erfindung betrifft eine Maschine zur Herstellung einer Faserstoffbahn, insbesondere Papier-, Karton- oder Tissuebahn, mit einer Trockenpartie (1) die eine oder mehrere Trockengruppen (2,4) umfasst mit jeweils mehreren beheizten Trockenzylindern (5), welche von der Faserstoffbahn umschlungen sind, wobei die Faserstoffbahn eine erste und eine zweite Seite hat und so durch zumindest eine der Trockengruppen (2) geführt ist, dass nur die erste Seite der Faserstoffbahn mit den Trockenzylindern (5) dieser Trockengruppe (2) in Berührung ist. die Erfindung ist dadurch gekennzeichnet, dass in Bahnlaufrichtung unmittelbar nach dieser Trockengruppe eine kombinierte Glätt- und Trocknungsvorrichtung (3) angeordnet ist, die ein beheiztes Metallband (14) umfasst auf dem die Faserstoffbahn abschnittweise geführt wird, die ferner Mittel (17) umfasst mittels denen die Faserstoffbahn auf dem Metallband gepresst wird und in der die Bahnführung der Faserstoffbahn so ist, dass die Faserstoffbahn nur mit ihrer zweiten Seite mit dem Metallband (14) in Berührung ist.
