    The present invention provides an apparatus for the simultaneous application of pressure and microwaves to a curable assembly, comprising (1) a continuous press including two endless press belts forming a nip region, the press belts being disposed to apply pressure to curable assemblies inserted therebetween, and including an inlet and an outlet for the passage of curable assemblies, (2) a press chamber defined by the two substantially parallel belt surfaces in the nip region and by two side walls, (3) means to apply microwaves to the curable assemblies from at least one microwave generator through a waveguide forming an interface with the press chamber located in an opening in a side wall, and (4) dam means at the interface between the waveguide and the press chamber to withstand the lateral pressure exerted thereon by curable assemblies being pressed, and which effectively permits propagation of microwaves into the press chamber. The press includes a means at the interface between the waveguide and the press chamber to substantially equalize fringing electric fields before the microwaves reach the curable assembly to be treated by pressure and microwaves and the waveguide includes wave chokes. A method of curing assemblies is also disclosed.

    The invention relates to wood processing in industrial production, in particular, to equipment for the production of wood-based sheet materials.
    The purpose of the invention is to improve the quality of pressing wood materials.
    Fig. 1 shows a schematic of the continuous pressing device, side view; figure 2 - section A-L in Fig, 1; Fig. 3 is a schematic diagram of the pressing zone of the device, top view; figure 4 is an insert with parallel metal plates; Fig. 5 is a schematic of the lubricant coating unit, the top pid; figure 6 - the same, with injectors; in fig. 7 - the same, in the form of an endless plastic tape; jHa FIG. 8 is a side view of a quarter-wave drossel with a ceramic insert; figure 9 is a diagram of the stop with the node; figure 10 - section bb in fig.Z; in fig. 11 - quarter wave throttle circuit; on Fig - the same cross section.
    A device for continuous pressing of wood-based materials includes the upper 1 and lower 2 infinite metallic pressure tapes, in the middle of which there is an extrusion chamber 3 with side walls 4 and a heating unit for packages 5 in the microwave range, made in the form of extrusion measures 3 parallel to the planes of the pressure tapes 1 and 2 of the waveguide 6 with the CB I-generator 7 and installed at the end of the waveguide 6 in the plane of the side wall 4 of the chamber 3 of the stop insert 8 made of radio transparent material and mounted at the top and bottom of the stop insert 8 parallel to the axis of the waveguide 6 quarter-wave chokes 9, the stop insert 8 can be made of aluminum layers with air gaps and equipped with a lubricant coating unit, which, in turn, is designed as an infinite plastic tape.
    Quarter-wave chokes 9 provide physical contacting of the waveguide 6 with pressure tapes at a point located at a distance equal to 1-4 wavelengths from the entrance to the choke 9,
    The quarter-wave chokes 9 have a total length of ./2 wave for the limit5

    to reduce the possibility of arcing at the point of actual contact of the waveguides 6 with the pressure tapes 1 and 2 and to prevent destruction, each waveguide 6 being used with two throttles 9, one above and one below.
    The stop insert 8 can be made in the form of a ceramic material or a reinforced element containing spaced metal layers arranged normally to the vector of the electric component of the microwave field, between which the radio-transparent layers in the microwave range are located, and also in the form located on the side facing Pressing chamber 3 is made of plastic.
    The operation of the device is as follows.
    Cured packages of wood materials are delivered between the upper 1 and lower 2 endless metallic pressure tapes, which gradually prepress the bags and, after they are pressed, move the latter to the chamber pressing — to the heating unit of the packages 5 with a moisture content of 5-20% by weight, where the packages exposed to electromagnetic microwave energy from 100 to 10,000 MHz, while the packet is heated to the curing temperature of the binder, the number of which is assumed to be 1-10% of the dry weight of wood, and when using foil For resin resins, the temperature of wood materials is set to 100-170 ° C, with a linear speed of 0.15-15 m / min and a package pressing pressure of 28-70 kg / cm or more, after which the compressed wood material is discharged and the cycle is repeated .
    The device provides an increase in the quality of the wood material due to the uniform heating of the bag.
