Abstract (en)
[origin: US4883546A] There is proposed a process for the manufacture of wood fiber boards, wherein by far the largest part of the outer layers to be conventionally sanded away no longer consists of wood fibers but of wood dusts of a defined particle size, a material which is available as waste from other consolidations of wood raw materials. By employing the process of the invention, it also is possible to achieve an only small density drop towards the center of the board, so that this process is particularly suitable for the manufacture of medium density wood fiber boards with a weight of 600 to 950 kg/m3.
