    The invention relates to the woodworking industry and can be used in the manufacture of chipboard.
    The purpose of the invention is to reduce energy consumption and improve the quality of the plates.
    Fig. 1 shows a device for the continuous manufacture of an endless web of chipboard, a general view; figure 2 - press part of the device; Fig. 3 shows a part of the press in the area of plate entry into the press gap.
    The device comprises a spreading machine 1, an endless forming tape 2 in the form of a textile tape, a high-frequency heating device 3, a pre-pressing press 4, a take-off device 5 in the form of a curved support table with a take-off edge 6, a take-off rollers 7-11. The final pressing device comprises a pressing roll 12, partially covered by a steel tape 13, passing around a take-off roll 14, a take-up roll 15, a hold-down roll 16 and a backpressure roll 17 pressing the steel tape 13 to; the cracking roll 12 and thereby forming a press gap between these two rolls. A coil 18 is provided in the device, from which the paper web 19 runs off through the take-off roll 20 in front of the pressing gap between the press roll 12 and the back pressure roll 17.
    From the point of incidence of the paper web 19 on the steel tape 13 to the press nip, the paper web 19 is already firmly attached to the winding roller 17 of the backpressure steel tape 13 in such a way that no relative movement between them is possible.
    A coil 21 may also be provided on top, from which the second paper web 22, through the deflecting roller 23, hits the pressing roller 12 immediately before the pressing gap.
    At the end of the diverting device 5, small diverting rollers 24 are provided, around which the textile tape 2 rotates. These rollers have a diameter of approximately 6 mm and their axis is held by comb-like protrusions entering between the polycings.
    molds on the leading edge of the diverter 5.
    In the direction of pre-compressed preformed chipboard 25 lying on the textile tape 2, a flat support 26 is triangular in cross section behind the outgoing rollers 24, through which the cooling channel 27 passes. The support on the surface of the support guide 26 passes along the tangent to the outgoing rollers 24 and felling 17 back pressure.
    The device works as follows.
    Mixed 1m chips are bonded to a textile belt 2, which passes through a high-frequency heating device 3 to the pre-pressing press 4, where the chips are heated to 50-60 ° C. In the pre-press, the preform is compacted by no more than 50%. This is enough to ensure the transfer of the plate to the steel strip without disrupting the structure, then the workpiece is fed to the device for final pressing. The plate enters the pressing gap, which is formed by an extruded roller 12 and a counterpressure roller 17 enclosed in steel tape 13. The pressing pressure is maintained in the region after this pressing gap due to the tension of the steel tape 13, and this pressure is sufficient for residual adhesion before leaving the press roll 12.
    The retracting edge 6 of the table 5 is quite close before the pressing gap between the backpressure roller 17 and the pressing roller 12 and close above the backpressure roller 17, so that the pre-pressed chipboard lying on the textile tape 2 falls on the upper side of the steel with almost no change in direction. tape 13 and then included in the pressing gap. The presence of a cooling channel 27 in the support guide 26 prevents the heating of the support surface due to thermal radiation from the side of the steel tape 13. During operation of the device, the spreading machine 1 continuously mixes the chips with the drying agent onto the continuous textile with the forming tape 2. Formed. the chipboard blank is heated in a high-frequency heating device 3 to a temperature that is safe for textile tape 2 and otherwise lying below the binding temperature in the actual medium. This preheating increases the compressibility of the 1o-ppt wood billet to the pressing plate in the following pre-press press 4. After leaving the pre-press 4, the chipboard preform has a significantly smaller thickness and is already of such strength that it is possible to transfer the pre-pressed wood billet - a slab plate without disturbing the structure from the textile tape 2 to the steel tape 13 in the area of the diverting edge 6. In this case, it is assumed that the textile tape 2 and the steel tape 13 have substantially the same oKp i / rHbie speed. In addition, the chipboard harvesting in this area is pressed, so that the paper nolotno can no longer make changes in length, which could lead to disruption in the chipboard harvesting. Therefore, the paper web 19, without sacrificing quality, is sash- ed when the web is manufactured on a wood particle board in the pressing gap onto the web.
    The device provides for the use of a flexible textile tape, which can take very small radii of curvature and due to this can rotate around the retraction edge, which can be located very close above the steel tape before it runs onto the pressing roll and can be transferred on a flexible textile fabric. tape the workpiece on the steel tape. The workpiece passes an exceptionally short section of the path without a moving support, thus no friction can arise and the danger of thrust and deterioration of the finished chipboard is prevented.
    With a support guide, the latter is so short. -
    54346
    This means that the friction arising due to the support on the upper side of this support) ian- is equal to friction so that the danger of thrusting is lost.
    The use of a flexible textile tape ensures the use with an increased efficiency of high-frequency heating in a triple, as follows: a copy of an elastic tape from -. d to turn off from the material having especially small dielectric losses. This leads to a very uniform progression of the wood-shaving plate. When using the device, up to 0% of heat energy is saved.
