ABSTRACT:
An arrangement for making a multi-layer particle board having several layers of a pressed fleece with two outer cover layers of lignocellulose-containing slender oriented particles mixed with binder material. The particles are strewn to form a lower layer onto the fleece carrier, while they are simultaneously oriented. A middle layer is applied onto the lower cover layer, and an upper cover layer is strewn onto the middle layer under orientation of the particles. At least a part of the slender particles for the cover layers strewn prior to orientation in the opposite direction relative to the transport direction of the fleece carrier, so that in the region of the cover layer facing away from the center layer, the length of the slender particles increases with the distance from the center layer.
