ABSTRACT:
The present apparatus deposits a fleece of wood chips, particles or shavings on a conveyor belt for manufacturing panels. In order to avoid a uniform orientation of all particles in one direction and to assure an orientation of the particles in all directions in substantially uniform distribution, there is provided a particle flow disturbing device for disorienting the chips, particles or shavings as they are directed toward a conveyor belt. The particle flow disturbing device includes a plurality of screens, which intersect at a common axis, which is located slightly above and across the conveyor belt and which extends normal to the direction of movement of the conveyor belt. The wood chips are directed downwardly through the screens by an air current flowing generally in parallel to the conveyor belt to mix the descending wood chips. The common intersection axis of the screens is located upstream of the opposite edges of the screens with respect to the air current. The lowermost screen extends in parallel to the belt and the opening angles between adjacent screens is preferably the same.
