- 21 - Device for Driving a Material Web Abstract A material web 9 to be dried runs across a first drying cylinder 11 ontowhich it is forced by a concurrently running continuous drying wire 10. Thereafter, the web and the drying wire proceed jointly from the first drying cylinder 11 to a suction guide roll 21. From the latter, at least the drying wire 10 returns to another drying cylinder 12. This path of the drying wire 10 defines a wire space S. Blown into this wire space, for instance by means of a blow pipe 48, is drying air at uniform distribution across the machine width and sucked out again by the suction guide roll 21. This suction air is blown at the material web 9 by means of a circulation air fan 49, at the circumference of the suction guide roll 21, and is sucked away again from there by means of an exhaust air fan 44. Fig. 1.
