摘要:
A multi-cylinder dryer of a paper machine, has at least one drying cylinder (10) and at least one roll (11, 12) located at a different height to the cylinder and at a distance to it in the machine direction. A paper web (14) travels from the drying cylinder (10) to this roll (11, 12). Dry air is brought to the dryer through a beam (13) located in front of the web (14) in the machine direction, the air is directed by means of nozzles (33) in the beam into a throat (21) between the drying cylinder (10) and the web (14) mainly to intensify the drying effect. A doctor (27) keeps the surface of the drying cylinder clean. The beam (13) forms with the roll (12) a smooth, high channel (25), at least on the side of the roll (12), for the passage of the web during a disturbance.
