ABSTRACT:
A continuously operating heat-treatment press in which a continuously advanced layer (7) of material under pressure, for example including glue-coated wood chips, is heated dielectrically. The press is of the kind which comprises at least one endless, continuously running press chain (8), for maintaining a vertically acting press force on the layer (7) of material, said press chain (8) being formed of mutually linked support elements. The press surface of the support elements in the press chain (8) comprises mutually electrically insulated metal rods (23) extending in the transverse direction of the chain. At least one stationary electrode plate (28) connected to a high frequency generator is arranged adjacent said metal rods (23).
