Date Jun. 6, 1996A device for levelling a particulate material web (3), such as a wood-fibre mat laid out on a wire (2) and intended for the production of wood-fibre boards, the material web being moved in relation to the device, comprises a rotary shaft (4) and a plurality of elliptic discs (6) mounted thereon. The shaft (4) is adapted to be arranged transversely of the direction of movement of the material web (3) and extends through the centers of the discs (6). The discs (6) are mounted at an axial distance from one another so as to rotate with the shaft (4). About their minor axes, the discs (6) are so inclined in relation to the shaft (4) as to have a circular axial projection.

    Abstract: PCT No. PCT/SE94/00591 Sec. 371 Date Nov. 30, 1995 Sec. 102(e) Date Nov. 30, 1995 PCT Filed Jun. 16, 1994 PCT Pub. No. WO95/00261 PCT Pub. Date Jan. 5, 1995In a method for separating heavy particles from a particulate material containing such heavy particles, use is made of a device having a Coanda sifter, which is adapted to receive a flow of the particulate material and which has a downwardly-facing, convexly single-curved surface (9), and a zigzag sifter (13) arranged after the Coanda sifter and having a plurality of zig-zag-shaped vertical walls (14) which are perpendicular to the axis of curvature of the single-curved surface (9) and define between them channels (15) extending upwards in zig-zag fashion. The particulate material is transported to the Coanda sifter and is conducted over its convexly single-curved surface (9) to have imparted to it a direction of motion (P1, P2) which is dependent on the weight of the particles and in which the particles are guided into the zigzag sifter (13). The particles are guided into the channels (15) of the zigzag sifter (13) in the lower portions thereof and from the side parallel to the channel walls (14). The particles are transported up through the channels (15) with the aid of a flow of transport air which is so adjusted that the heavy particles are separated in the zigzag sifter. (13).

    Abstract: The present invention refers to a device for spreading and distributing particles on a material web (9), such as glue-coated wood fibres on a wire or a conveying belt for production of wood-fibre boards, which material web (9) being moved relative said device, comprising forming rollers (7) with several, transverse the direction of movement of th e material web, arranged and along a rotating axle (11) distributed, essentially oblique distributing means (12), which rotate with said axle (11 ). The essential with the invention is that several forming rollers (7) are arranged successive after each other on increasing height and are arranged in such a way that the distribution means (12) extends down into the material web, whereas the particles at each axle (11), by the rotation of the distribution means, spread across the material web (9) to an even layer of homogenous distributed particles.
