    A method and an apparatus for the continuous manufacture of particle board from a mat of cellulose based material in the form of particles, fibers or the like, together with at least one heat hardenable binder, features a high frequency heating station 4 disposed between a scattering station 2 and a finishing press 9. The mat 3 scattered in the scattering station 2 is continuously fed on an endless conveyor band 1 through a working gap defined between upper and lower electrode plates 5 and 6 of a high frequency capacitive heating arrangement in the high frequency heating station 4. A recirculating cover band 7 contacts the upper surface of the mat and the mat is moved with full-area contact between the upper and lower electrode plates 5 and 6, i.e. without any form of air gap. Several variants are described, in particular the upper and lower electrode plates 5 and 6 can be constructed to compress the mat to a certain degree. In the FIG. 2 embodiment several sequential pairs of electrode plates 5, 6; 5', 6' are used to heat the mat in stages with compression 10 taking place between sequential pairs of electrodes.

    The invention relates to the woodworking industry, in particular to equipment for the production of chipboard.
    The purpose of the invention is to increase productivity.
    Fig, 1 shows a diagram of the device, side view; Fig. 2 shows the layout of the additional electrode plates.
    A device for producing chip, fiber or similar plates includes a molding unit 1 with a conveyor 2 for continuously moving a layer of a carpet 3 of particles containing lignocellulose and / or cellulose and a binder mixed with particles, a high-frequency heating unit 4 with opposite electrode plates 5, forming the working gap 6, in which the layer-cover 3 is located, mounted between the conveyor 2 and the covering tape 7 moving together with it, the subpress 8 for sealing the heated layer of the carpet and a mounting device 9 and an actuator, the high-frequency heating unit 4 additionally having electrode plates 10 installed behind the main electrode plates 5, between which a pressure roller device 11 can be provided, the height of the working gap 6 main 5 and additional 10 electrode plates in the direction of transporting the layer - Carpet 3 decreases,
    The device works as follows.
    The layer-carpet 3 goes to the high-frequency heating unit 4, which with the help of electrode plates 5 and additional electrode plates 10 heats the layer-carpet 3 to an optimum temperature of 40-80 С
    33362
    then the layer-carpet 3 is compacted on the pressing device 8 or the roller device 11 and pressed on the pressing device 9, then the plates are removed and the cycle is repeated,
    I
    The use of the main 5 and additional 10 electrode plates provides an increase in the productivity of the device operation due to uniform heating of the layer of the carpet.
