Abstract
A drying end which comprises a plurality of drying groups. Referring to FIG. 2, each drying group has its own endless support belt (171-175) which travels together with the web alternately over drying cylinders (101-138) and guide rollers. In each drying group, at least some of the drying cylinders lie in a row of cylinders (161-168) which is arranged approximately vertically. Within the first drying group (160/161) the web travels downward through a vertical cylinder row (161), the lower side of the web contacting the cylinders. In the second drying group (162/163), the web first of all travels upward, the upper side of the web contacting the cylinders. At least two drying groups have two vertical cylinder rows (162-167). Referring to these later two groups, the rows of guide rollers in one drying group are arranged outside the corresponding cylinder rows, and in the other drying group the guide rollers are arranged inside the cylinder rows.
