Wind room for spreading and moulding a huge material on a moulding tape

摘要

Wind scatter chamber for spreading and moulding a material capable of forming (8) to a single or multi-layer material layer (11) on an endless conveyor belt (12) during the production of material plates in a press, where the wind scatter chamber (10) a chamber (1) with a material supply (22) for introducing the material (8) has an air flow (13) parallel to the forming band, the air flow (13) being discharged into the chamber (1) via an entrance aperture (14) and at the other end of the chamber (1) via an exit aperture (15),where a screening device (17) for the coarser parts of the material (8) is located in a first area (I) of the chamber (1) with the material input (22) and a space height (2a) is formed by the distance between the ceiling (23) of the chamber (1) and the mould band (12), characterized by the fact that in flow direction (7) at least in a further range (II, III, IV) a wall changing the height of the room (4, 5, 6).
