Abstract

Zum Trocknen einer laufenden Materialbahn, insbesondere einer gestrichenen Papier- oder Kartonbahn, ist es bekannt, die Bahn zunächst in einem Infrarot-Trockner (1) mit Infrarot-Strahlern (4) vorzutrocknen und anschließend in einem Lufttrockner (2) mit Luft weiter zu trocknen. Nach der Erfindung wird der Lufttrockner (2) so betrieben, dass der Wärmeübergangskoeffizient zwischen der Trocknungsluft (8) und der Bahn (B) in Bahnlaufrichtung (L) ansteigend verläuft.

For drying a running material web, in particular a coated paper or cardboard web, it is known to first pre-dry the web in an infrared dryer (1) with infrared emitters (4) and then to dry it further with air in an air dryer (2) , According to the invention, the air dryer (2) is operated in such a way that the heat transfer coefficient between the drying air (8) and the web (B) increases in the web running direction (L).
