Abstract
An arrangement in an apparatus for drying a fiber web, in which apparatus the fiber web (5) is dried between two tight bands (1, 2) moving in the same direction and turning around turning rolls (6a, 6b, 7a, 7b). The first band (1) is heated by means of a pressure chamber (9) and the second band (2) is cooled by means of a water chamber (10). The fiber web (5) is led together with at least one felt or wire (3, 4) through a drying zone formed by the bands (1, 2) in such a way that the fiber web is in contact with the surface of the first band (1) and the felt or wire (3, 4) is between the fiber web (5) and the second band (2). The arrangement comprises means for supporting the wire or wires (3, 4) in such a way that the fiber web (5) is exposed to a compression pressure by the effect of the wire or wires (3, 4) substantially immediately upon coming into contact with the first band.
