<p>A seal arrangement in a fibre web drying apparatus, in which a fibre web (5) is dried between two tight bands (1, 2) that move in the same direction around turning rolls (6a, 6b, 7a, 7b). The first band (1) is heated by a pressure chamber (9), and the second band (2) is cooled by a water chamber (10). The fibre web (5), with at least one wire (3, 4), is led through a drying zone formed by the bands (1, 2) so that the fibre web is in contact with the surface of the first band (1), and the wire (3, 4) is between the fibre web (5) and the second band (2). The drying apparatus comprises side chambers (11) in which pressure medium dripping from the chambers (9, 10) collects. The ends of the side chambers (11) are sealed with an end seal (13), which comprises elongated sealing elements (15) attached at at least their one end and having a length that is greater than the height of the area to be sealed.</p> |
