发明名称 Apparatus for drying a fiber web
摘要 The invention relates to 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 cooled second band (2). The surface (11) of the first band (1) bearing against the fiber web (5) is at least partially formed in such a way that reflection from it to a specular reflection angle is reduced substantially. Excessive gloss can then be removed from the surface of the fiber web (5) and the end product to be manufactured of it.
