ABSTRACT:
A method of forming a multilayer blanket of wood particles adapted to be pressed into particle board in which a particle separator scatters the wood particles in separate streams by particle size. The finest-particle streams are deposited directly, i.e. without interception while the fine and coarse particle streams are intercepted by downwardly inclined plates formed with parallel channels for guiding the respective particles into separate layers on a moving support to form the blanket. The plates are vibrated so that the individual particles are oriented as they pass along the respective channels.
