    - ra; naya -pr>, in FIG. 7 is a sectional view of the surface of the grinding brush.
    FIG. 3 is a perspective view of a grinding device of a cooling device; in FIG. 4 cut from FIG. 3; in FIG. 5 - principle: operation diagram of grinding grinding device; in FIG. 6 • a longitudinal section of the grinding brush;
    A device for the continuous production of decorative layered materials consists of winding units 1,2 with feeding drums 3, 4 placed in them, which contain paper webs impregnated with a pre-condensed thermosetting resin, forming a decorative layered material, Resin-impregnated paper webs are continuously wound with feeding reels 3, and put together in front of the belt press with the formation of the layered structure 6. This layered structure 6 then enters the belt press 5 and there continuously under heat and pressure over the surface is cured to form a decorative laminate.
    Continuously operating belt press 5 consists of a lower press belt unit 8 and an upper 9 located
    1838133 AZ over each other. Press Belt Units
    8, 9 consist of each of two pairs of drums
    10, G>, 12, 13 and endless pressing tapes Μ, · 5 directed around the drums 10,
    11, 12, 13, and pulled by means of hydraulic cylinders 16. Four drums 10, 11, 12, 13 are mounted for rotation in a press frame (not shown in the drawing). At least, respectively, one drum of both press belt assemblies 8, 9 is driven so that both press belts 14, 15 move towards each other.
    Between the lower branch of the upper press belt 15 and the upper branch of the lower press tape 14 there is a reaction zone 17, with which the laminated structure 6 is pressed. The surface pressure exerted on the laminated structure 6 in the reaction zone 17 of the belt press 5 is hydraulically or mechanically transmitted via pressure plates 18, 19.
    During hydraulic pressure transfer, a fluid working sediment placed under pressure is placed in the volume between the pressure plate 19 and the inside of the press belt 15 (see Fig. 2) using the upper press belt assembly 9. On both sides this volume, the so-called pressure chamber 20, limited by the contact surface seal 21, ring-closed by itself, placed in the pressure plate 19 and sliding on the inside of the press belt 15. Synthetic oil is mainly used as the working medium. However, in the same way, you can use gas, such as compressed air,
    To mechanically produce surface pressure acting on the layered structure 6, stationary rollers 22 are located between the pressure plate 18 and the inside of the press belt 14, as shown in FIG. 2, using the lower press belt assembly 8. Using hydraulic cylinders 23, the pressure plate 18 together with the rollers 22 is fed to the inner side of the press belt 14.
    Needless to say, the pressure plate 19 can also be equipped with a mechanical pressure transmission system, or a hydraulic pressure transmission system of the pressure plate 18. If necessary, the pressure transmission can also be carried out in a combined way hydraulically mechanically, both of which are used simultaneously.
    The pressure plate 18, 19 can be made heated. The heat is then transferred from the pressure plate 18, 19 by means of rollers 22 or by means of heat-conducting elements to the press tape 14.15 and from it to the layered structure 6 in the reaction aeon 17. The pressure plates 18 , 19 of the tape press 5 can also be divided into heating and cooling zones, so that the layered structure 6 is cooled already in the tape press 5 under the influence of pressure.
    After compression, the material 7 passes into the grinding and cooling device 24. Subsequently, the material 7 is wound in the winding device 25 onto the feeding drums 26. Alternatively, the material web 7 can also be divided into transverse cutting stations 27 into separate plates 28, which are then stacked in stacks for transport to the side on pallets 29.
    The entire technological process is controlled by a computing device located in the cabinet of the complete switchgear 30. To enter the process parameters, the user uses the data input terminal 31. It goes without saying that the computing device in the cabinet of the complete switchgear 30 can also be connected to an external host computer located, for example, in a central installation of electronic data processing, to provide production management and feedback on production data for further Further analysis directly from the central unit.
    The grinding and cooling device 24 has a frame 32 with support shoes 33. On the frame 32 is a bath-shaped lower part of the housing 34 and above it the upper part of the housing 35. Inside the upper part of the housing 35 and the lower part of the housing 34 there is an inner bath 36 surrounded by an outer bath 37, formed by the body. The upper part of the housing 35 using the seal 38 sits on the lower part of the housing 34 and thereby seals the inner bath 36. For maintenance purposes, the upper part of the housing 35 can be removed from the lower part of the housing 34 due to the piston assembly 39. On the input and output slots 40 between the upper part of the casing 35 and the lower part of the casing 34, the web of material 7 enters the inner bath 36 of the grinding and cooling device 24, slides along the seal 38 in the upper part of the casing 35 and the lower part of the casing 34, so that the entrance and exit slits 40 are ohlazhdayusche5 oval and second device 24 is sealed relative to the outside.
    In the inner bath 36 of the lower part of the housing 34, there is a diamond brush 41 equipped with diamonds, round in cross section, which consists of a cylindrical hollow roller 42, the bosses 43 are welded at both ends, with which the grinding brush 41 mouths in the walls 44 of the inner bath 36 ( see FIG.
    is rolled with the possibility of rotation by side 52 of the web of material 7 and its pressing. For rollers 51 three-wheel drive, as they rotate due to: neniya cloth material. Reference 50 may be brought in or retracted
    3). An axial boss 43, mounted on the front side of the grinding brush 41, passes through the wall 44 of the inner bath 36 into the outer tub 45. A gear 46 is placed on the axial boss 43 in the outer tub 45. The motor 47 is located in the relay 32, on the shaft of which there is a drive gear 48. A gear belt 49 is pulled through the drive gear 4B and gear 46, so that the motor 47 rotates the grinding brush 41.
    In the support block 50, located in the upper part of the housing 35, two backpressure rollers 51 are mounted for rotation, and they are located above the grinding brush 41 in the immediate vicinity of it. The support block 50 is adjusted so that the counter-pressure rollers 51 are in contact with the front, the reverse side 53 on a part of the volume of the grinding brush 41 is under counter-pressure, its own movement is not required!
    perpendicular to the web of material 7, in order to adjust the pressure of the rollers of the material 7.
    Grinding the reverse side 53 of the web of material 7 with the diamond-equipped grinding brush 41 is very effective and can be carried out at higher speeds than this was further refined]; | in order to prevent it from grinding in a stationary position, which can be caused by production, the support block 50 can move the fowler brush 41, so that the pressure of the back pressure rollers 51 and the reverse side 53 are stopped so that with this it is possible51 back pressure to the web is still possible since Thus, the device is generally deserted for ovulation of the layered material. However, to take place during breaks to the side in the direction from the material schlipot 7, it is removed from the grinding brush 41. For automation, a displacement sensor can be placed on the material sheet 7, signaling that it is stopped by the computing device 5 in the cabinet of the complex switchgear 30, which, in turn, removes backpressure rollers 51 in the support block 50 from the web of material 10 7.
    The operation of the device is as follows.
    Material 7 from the drums 3, 4 of the winding units 1, 2 enters in the form of a bag for 15 press 5. The pressed laminated material 7 enters the grinding and cooling. device 24.
    During grinding of the reverse side 53, the web of material 7 is simultaneously cooled 20 in the grinding and cooling device 24, for which there is cooling water in the inner bath 36, which is filled with this water so that both sides 52, 53 of the web of material 7 25 are completely covered with cooling water . The exit of cooling water from the internal. her bath 36 is prevented by the seal 38. However, due to leakage, small amounts of water can exit 30 of the inner bath 36, as well as be carried away by the movable web of material 7 through this seal. Such water captures. The external bath 45 is collected and collected therein, so that the exit of cooling water 35 from the grinding and cooling device 24 is effectively prevented.
    The principle of operation of the grinding and cooling device 24 is explained in more detail in the circuit diagram of 40 of FIG. 5. Through the cooling water supply 52, fresh cooling water is supplied to the inner bath 36 of the grinding and cooling device 24. From the inner bath, cooling water can be drained 45 by means of a return pipe 54 for cooling water. By controlling the inflow in the supply of cooling water and the drain in the return line 55 for cooling water, both the temperature and the level of filling with cooling water in the inner bath 36 can be kept constant 50 to ensure optimal cooling of the laminate web 7, Leaking cooling water collected in the outer bath 45, is discharged through the return line 56 for water injection.
    Grinding dust resulting from grinding of the reverse side 53 of the web of material 7 is carried away by cooling water. This grinding dust dissolved in cooling water is transported with waste water in a cooling water return pipe 54 and in an injection return pipe 56 to a filter 57, in which grinding dust is removed from the used cooling water. The purified waste water is then discharged from the filter 57 into the supply pipe 58. For this, it can still be sent through a heat exchanger so that the heat absorbed during cooling of the web of material 7 can be returned.
    In order to keep the amount of water collected in the outer bath 37 as small as possible, a small vacuum is created in the inner bath 36. For this, a vacuum pump 59 is located in the frame 32 of the grinding and cooling device 24, from which there is a connecting pipe 60 to the inner wall 36 in the upper part of the housing 35. This reduced pressure prevents the cooling water from escaping from the inner bath 36 to the outer bath 45. To tighten under vacuum, the inner bath 36 there are ribs 61.
    The grinding brush can be equipped with solid materials, such as cubic boron nitride. However, grinding brushes equipped with diamonds, which both have an increased service life and a high feed rate of the material web 7 in the grinding and cooling device 24, proved to be particularly effective, using higher feed speeds when processing the back side 53 of the material web 7 with equipped with a diamond grinding brush 41 is only ensured by simultaneous cooling during grinding.
    One particularly preferred embodiment of the grinding brush 41 involves the presence of spiral grooves 63 on the cylindrical web of the roller 69, forming alternating grooves 63 and protrusions 64. which are equipped with diamonds that have their own grinding effect on the webs of material 7. Due to the spiral arrangement of the protrusions and grooves 63 and 64, , on the one hand, a completely uniform grinding effect on the back side 53 of the fabric 7, The grinding dust resulting from grinding is taken from the surface of the fabric 7 into grooves 64 and from them with cooling water is discharged through a return pipe.
    The protrusions 63 can be equipped with diamonds in a galvanic way. A diamond composite layer can be welded onto the protrusions 63, which consists of a mass of diamond particles randomly oriented in a metal matrix, spliced together at extremely high temperatures and pressures.
    The device can be used for the manufacture of arbitrary materials, and the combination of grinding and cooling in one unit increases the production speed for the continuous production of material.
