Abstract: The invention relates to a device for aligning and depositing elongate particles covered with at least one bonding agent on a continuously moving support so as to form a non-woven fabric for the subsequent production of boards. Said device comprises a dosing hopper, a unit for transferring the particles to an orientation unit consisting of several rollers having several compartments, said rollers being arranged at a distance from each other on a horizontal surface and at right angles to the direction of displacement of the continuously moving support. The alignment faces of the rollers, whose surfaces define the compartments and are embodied in an airtight manner, are configured in such a way that, at least in the area of their free ends, they are curved and/or bent against the direction of displacement of the continuously moving support.
