Abstract
Plate having several layers of a pressed fleece, whose outer cover layers are of preferably lignocellulose-containing slender oriented particles mixed with at least one binder material. At least in a region of the cover layer facing away from the center layer, the length of the slender particles increases with their distance from the center layer. The region may include the entire cover layer. The slender, shorter particles are homogeneously arranged in the intermediate between the region of the cover layer.
