<p>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 the 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.</p> |
