Abstract (en)
[origin: WO2021156520A1] The invention relates to a wind distributing chamber and method for distributing and forming a free-flowing material (8) to form a material nonwoven (11) on an endlessly revolving forming belt (12) during the course of the production of material panels in a press, the wind distributing chamber (10) having a chamber (1) with a material feed (22) for introducing the material (8) into an airflow (13), a first chamber height (2a) being variable in a first region (I) of the chamber (1) by the distance between ceiling (12) and the forming belt (12), and the chamber height being variable in a further region (II, II, IV) in the flow direction (7). A wall (4) that continuously reduces the chamber height (2b) is arranged below the ceiling (23) in the second region (II) and a wall (5) continuously increasing the chamber height is arranged in the third region (III).
