<p>A method and an apparatus for manufacturing fibre board sheets according to the dry method. The fibre material is defibered in a defibrator (3), mixed with resin (7) and dried with hot gas in a tube drier (5). After the drying the drying gas is separated in a cyclone (15), whereafter the fibre material in a forming station (16) is formed to a fibre mat, which is pressed in a pre-press (27) and finally pressed in a hot-press (28). Due to the location of the cyclone (15) above the forming station (16), the fibres are transferred directly from the drying to the forming with substantially maintained temperature, which reduces the energy demand.</p> |
