ABSTRACT:
Apparatus for the production of a middle layer of chipboards or the like and/or for the manufacture of chipboards formed only from middle layer material includes at least one spreading station associated with a spreading chamber arranged above a moving support for the reception of a chip layer or the like, the entire fine or coarse materials serving for the formation of a type of middle layer being fed by at least one metering tank to the support. The apparatus is further characterized in that at least one inclined screen which can be reciprocated in an essentially horizontal direction is disposed underneath the delivery point of the metering tank and a spreading roll is disposed underneath the lower edge of the screen in parallel to the screen edge, the roll serving for feeding the coarser material to the space lying beneath the screen.
