ABSTRACT:
Method for one of drying and cooling a web in which a web is passed over an arcuate circumference of a blow device, a gas is directed from an interior of the blow device at the web through first openings formed in a mantle of the device to form a support zone between the mantle and the web, and moistened exhaust gas is drawn from the support zone into the interior of the blow device through second openings formed in the mantle. A revolving edge support is arranged at each end of the blow device to support the web during the passage of the web over the circumference of the blow device, the edge supports being separate from the blow device, and the edge supports include one of interior circumferential and friction surfaces to seal the support zone. A device for one of drying and cooling a web includes an elongate blow device having a circumference over which the web is guided to run, intake and exhaust ducts arranged in an interior of the blow device and a mantle including first openings in flow communication with the intake duct and second openings in flow communication with the exhaust duct. The device also includes a revolving edge support arranged at each end of the blow device for supporting and guiding the web during running of the web over the circumference of the blow device, the edge supports being separate from the blow device, and support constructions for supporting the blow device in a stationary position.
