摘要： When drying a web-formed material (1), preferably glass fibre, the web-formed material is passed, in contact with a gas-permeable dryer screen (3), through a drying plant (21). One or more fans (27) blow hot process air against, and through, the web-formed material (1) in order to dry it. A chamber (27a), surrounding the fan or the fans (27), has a limiting surface that is essentially parallel to the surface of the web-formed material. This limiting surface has an opening (29a) that extends essentially across the whole width of the web-formed material (1). A distributing member (20), in the form of an arcuate perforated, sheet-formed element (90), placed outside the chamber (27a), covers the opening (29a) completely. With the distributing member (20) a first flow of process air is divided into a large number of jets, distributed over essentially the whole of the angular area that faces the web-formed material (1). Thereafter, the jets are allowed to mix with one another again to form a second flow of process air, which is passed through a flat perforated, sheet-formed element (2a) that is positioned close to and extends over essentially the whole of the web-formed material (1), and then against and through the web-formed material (1) lying on the gas-permeable dryer screen (3).
