A stratified layer, for the manufacture of sheets, is formed from finely divided particles of material exhibiting a size distribution such as chips, fibers or the like, especially for the manufacture of wood chip panels, by forming a stratified mat on a substantially horizontal advancing surface by spraying particles of the material thereon, in such a manner that the finest particles are at at least one surface of the mat, through imparting a motion parallel to the direction of advance of the surface to the particles which are falling, causing the motion of individual particles to differ depending on the coarseness thereof so that different particles follow different parabolic trajectories and by collecting and removing particles which fall at least approximately vertically during said spraying. |
