ABSTRACT:
Method and apparatus are provided for equalizing the density distribution of pressed wood panels manufactured from adhesive coated bulk material. A bottom belt hopper has an outlet, the width of which is identical with the spreading width for the pressed wood panels being manufactured. Devices installed below the bottom belt hopper transport the bulk material as adhesive coated chip material onto a forming belt. Density deviations existing in the bulk material when it is removed from the bottom belt hopper are determined and correspondingly eliminated. If required, a density profile for a finished pressed wood panel is provided when the bulk material is taken from the bottom belt hopper.
