Abstract

Die Erfindung betrifft einen Prallströmtrockner zur Trocknung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn (1), bei dem die Faserstoffbahn (1) einseitig mit einer Heißluft-und/oder Heißdampfprallströmung beaufschlagt wird und sich mit der gegenüberliegenden Seite auf einem luftdurchlässigen, endlos umlaufenden Stützband (2) abstützt.
Dabei wird eine thermische Schädigung des Stützbandes (2) auch bei sich ändernder Bahnbreite der Faserstoffbahn (1) dadurch verhindert, daß zumindest die mit der Heißluft-und/oder Heißdampfprallströmung direkt beaufschlagte Randzone des Stützbandes (2) gekühlt wird.
