Apparatus and method for continuous production of materials

An apparatus and method for the continuous production of materials, preferably for producing material boards made of essentially non-metallic material, comprising a continuous furnace (1) for continuously heating material (3) on an endlessly circulating conveyor belt (10) and a press (2) provided downstream in the production direction (15), wherein the continuous furnace (1) comprises a plurality of magnetrons (4) for generating electromagnetic waves and hollow conductors (5) with outlet openings (6) for feeding the waves into a radiation chamber (14). The invention is intended to solve the problem of reacting to various operating modes for the continuous furnace and, in particular, to heat up the material used in the best possible manner for later pressing. The invention is characterized in that a control or regulating apparatus (17) is arranged for controlling individual or grouped magnetrons (4) in order to provide them with different powers (L) for producing a differentiated power profile (9), preferably in and/or transversely to the production direction (15).

Method for manufacturing high-density wood laminate material

This method for manufacturing a high-density strand board enables high-density strand boards to be formed by using about the same press pressure as press pressures required to form strand boards with common densities, so that the high-density strand boards can be produced without using special facilities and equipment. A pretreatment process P2 is performed on strands 5 before pressing. The pretreatment process P2 is comprised of a first treatment process P2a and a subsequent second treatment process P2b. At least one of beating, high-frequency treatment, high-temperature high-pressure treatment, high-water pressure treatment, repeated deaeration and dehydration treatment, and chemical treatment is performed in the first treatment process P2a, and roll pressing or flat press pressing is performed in the second treatment process P2b. A strand board B with a density of 750 to 950 kg/m.sup.3 is formed by using a press pressure of 4 N/mm.sup.2 or less.
