ABSTRACT:
A material web to be dried runs across a first drying cylinder onto which it is forced by a concurrently running continuous drying wire. Thereafter, the web and the drying wire proceed jointly from the first drying cylinder to a suction guide roll. From the latter, at least the drying wire returns to another drying cylinder. This path of the drying wire defines a wire space S. Blown into this wire space, for instance by means of a blow pipe, is drying air at uniform distribution across the machine width and sucked out again by the suction guide roll. This suction air is blown at the material web by means of a circulation air fan, at the circumference of the suction guide roll, and is sucked away again from there by means of an exhaust air fan.
