An apparatus for drying a fibre web, the apparatus comprising two endless bands that conduct heat well and are impermeable to air, which bands are arranged to run part of the way parallel with each other, the first band (1) being heated and the second band (2a) being cooled and the fibre web (3) being conducted together with at least one fabric between the bands (1, 2a) in such a way that the fibre web is in contact with the heated band (1) and the fabric is between the fibre web and the cooled band (2a). The invention comprises additionally a third band (2b) that conducts heat well and is impermeable to air, which band is located after the second band (2a) in the travel direction of the bands and forms together with the first band (1) a second drying zone.
An apparatus for drying a fibre web, the drying apparatus comprising a first and a second endless band that are impermeable to air and conduct heat well, first turning rolls, around which the first band is arranged to turn, and second turning rolls, around which the second band is arranged to turn, the first and the second band being arranged to run part of the way parallel with each other so that they form a drying zone between them, the first band being heated and the second band being cooled, and a fibre web and at least one fabric that forms an endless loop being conducted between the bands so that the fibre web is in contact with the heated first band and the fabric is between the fibre web and the cooled second band, as well as guide rolls for guiding endless fabrics,
