Abstract
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 defined 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). At least one band (1, 2) is guided by a shoe (11a, 11b) in such a way that the fiber web substantially immediately upon coming into contact with the first band (1) is exposed to the effect of the compression pressure of the pressure chamber (9). Then the drying of the fiber web (5) surface has no time to reduce the plasticity of the web surface and it is also possible to prevent the fiber web from pealing.
