Abstract: The invention relates to an improved machine for continuously compacting ligno-cellulosic or like materials, comprising two toothed conveyor belts mounted around drums, the teeth and valleys of these belts being located outside so that their stretched sides cooperate to compress a fibrous or like materials poured between these belts via a hopper. Compression rollers facilitate compression and cooperate with the resilient toothed belts to cause a pulsating effect of the belts on the materials. The invention is more particularly applicable to compacting ligno-cellulosic or like materials.
