ABSTRACT:
An apparatus for drying a continuously moving web has a housing defining a vertical zigzag path having a succession of oppositely directed and inclined stretches each flanked by a pair of parallel and confronting walls each in turn provided with an array of nozzles. Rollers are provided at the ends of the stretches for reversal and guiding of the web, and a blower is provided whose pressure side is connected to the nozzles for creating a gas cushion to each side of the web which supports the web and guides it along the path. Each of the walls is corrugated in a direction perpendicular to the direction of travel of the web, and the nozzles are provided on each side of the crests of the corrugations. The gas cushion is drawn off at the ends of the troughs of the corrugations.
