LAYER-FORMING APPARATUS, ESPECIALLY FOR THE PREPARATION OF PARTICLE-BOARD MATS

摘要

A layer-forming apparatus, particularly for the preparation of particle-board mats adapted to be compressed with heating in a platen or other press to form a coherent structure generally known as particle board, comprises a dispensing unit for metering the particulate matter onto a conveyor to form the layer and, between the dispensing unit and the conveyor, a classifying device for separating fine particles from coarser particles. The conveyor feeds a head which spreads the particles from the layer on a receiving surface. The receiving surface carries the mat and the head is designed to deposit the coarser particles of the layer from the conveyor either before or after the fine particles so that the fine particles form a facing zone on the bottom and/or top of the mat.
