<p>An arrangement in a dryer for a fibre web for sealing bands (5a, 5b) that move between a chamber (3) containing pressurized vapour and a chamber (1) containing pressurized water and transport a web (7) and a felt (8) between them, and also for sealing the edges of the chambers (1, 3). The arrangement comprises a closed recovery chamber (16) into which the edges of the bands (5a, 5b) extend and in which the vapour escaping from the vapour chamber (3) from between the band (5a) and the seals (9, 10) and the water escaping from the water chamber (1) from between the band (5b) and the seals (12, 13) gather, whereby the vapour and water can be discharged from the recovery chamber (16) such that they are cannot escape into surrounding air. <IMAGE></p> |
