    Disclosed is a system for continuously manufacturing and refining the surface of plate webs made from fleece, with at least one of the elements (10, 11) forming the pressing gap and being temperature regulated during operation having allocated to it means (28, 29) for applying paint and varnish. Furthermore, at least one stamping and/or profiling device may be provided for the plate web having cover layer particles pretreated with or without colour pigment, whereby an extremely large variety of possibilities for designing high quality plate surfaces is produced. <IMAGE>

    The invention relates to the field of the pulp and paper industry, in particular to installations for the continuous manufacture and finishing of a sheet web of fibrous material.
    The purpose of the invention is the efficiency of the installation.
    The drawing shows the proposed device, a General view.
    The plant for continuous fabrication and surface finishing of the sheet web 1 of mixed with at least one binding agent containing lignocellulose and / or cellulose shavings, fibers or similar particles, includes endless carrier 2 for a given carpet layer 3, driven around rollers or rollers 4, which change the direction and the rearranged tension roller 5, which in the direction of the arrow 6 through the guide plate 7 moves towards the gap 8 of the two-belt press 9. In addition, the installation contains an upper endless th rotating belt 10 and a lower endless rotating belt 11. between which the carpet layer 3 moves in the direction of arrow 6 during the passage and is subjected to the process step m preliminary and main compression, and calibration.
    On the side 12 of the strips 10 and 11 opposite to the layer 3 of the carpet throughout the pressing section 13, which consists of the preliminary pressing section 14 and the main pressing section 15, as well as calibration, there is a layer of slip coating 16 which, for example, may be made of rubber, vulcanized onto support 17 in press section 13.

    s
    In the pre-press section 14, the slip cover 16 is angled to each other to form a tapered pressing gap. These coatings may consist of slip coating modules, which, one after the other in the direction of movement 18 of the belts 10, 11, are displaced at an angle between each other and finally in the area of the main extrusion are installed parallel to each other.
    The slip coating 16 on the pre-pressing section before the start of the main pressing section 15 was performed with a constant or continuous curvature,
    On the side of the entrance to the press, above the layer-carpet 3, a device 19 is provided with rollers 20, 21 from which the profiled strip 22 can be pulled and directed onto the surface of the layer-carpet. Both rollers 20, 21 are provided, in particular, in order to allow volatile exchange between the rollers and thus ensure the continuous operation of the entire installation.
    Layer x over 3 and the carpet layer lying on the surface of the tape 22 are held together and synchronously through the pressing gap, whereby by means of a profiled tape
    22 and / or, by means of two-lamination final press ribbons 10, 11, decorative protrusions and recesses may be communicated to the sheet web 1, for example, in the form of a sandstone structure or shale. On the exit side of the press, the profiled tape 22 is transferred to the device 23 or, through this device 23, is lowered from the sheet web 1. The device
    23 consists of two rollers 24, 25, between which a volatile exchange can be made.
    Together with the use of the profiled belt 22, the making of the decorative protrusions and recesses can also be carried out only by means of one rotating endless belt 10, which in this case has surface profiling done in the desired manner.
    A two-liter final press may have a pair of rollers 26, 27 installed after it, which serves to carry out additional profiling operations.
    The following shows from the entrance to the press fixture 28,29 for coating for varnish and paint. In the illustrated embodiment, these devices are placed directly in front of the gap of the entrance to the press and are provided for the upper and lower sides of carpet layer 3. It may also be advantageous if you install fixture 28, 29 for coating at a greater distance from the horizontal gap. stitches 10, 11.
    Two-belt final presses may, if necessary, have a pair of pre-compression or compaction rollers in front of them and / or rollers provided on the entrance side of the press, changing direction for the belts 10, 11 of a two-belt final press, which can simultaneously be press rollers for rendering final pressing pressures. It may be beneficial, depending on the materials used in each case, to vary with temperature gradients along the pressing gap in order to establish optimal deformation and stabilization conditions for the carpet layer.
    The installation works as follows.
    The rollers 30, 31 transfer the mass of varnish or paint evenly onto the outer surfaces of the upper and lower endless rotating belt 10. 11. In some cases, the application may be sufficient to apply a lot of paint or varnish on one side of the carpet layer 3.
    Inside the pressing gap, the mass of paint or varnish is internally bonded to the carpet layer and during the passage through the press dries and at least substantially hardens, as a result of which, at the exit point of the two-belt final press, the rotating belts 10, 11 are separated from the finished sheet web 1 generally free from any paint residues and, accordingly, the sheet web retains its high-quality appearance.

    Invention Formula
    1, A plant for the continuous manufacture and finishing of a sheet of fibrous material sheet, comprising a heated pressing device in the form of a continuously operating two-belt finishing press with working surfaces forming a gap for pressing a carpet-layer sheet containing at least one binder chips, fibers or other particles containing lignocellulose and / or cellulose, roller-like agent for applying at least a one-side coating on a JA sheet Special feature for embossing and / or profiling, characterized in that. In order to make the installation more economical, the rollers of the means for applying at least a one-sided coating to the carpet layer cloth are installed with the possibility of their working surfaces contacting the working surface of the heated pressing device directly before entering the pressing gap.
    [2]
    2. The apparatus according to Claim. Distinguishing from the fact that the embossing and / or profiling device is a tape of a double-belt finishing press.
    [3]
    3. Installation pop. Distinctive - in that the embossing and / or profiling device is formed by one profiled strip, covering the feed rollers from the inlet side of the press and the discharge rollers from the outlet side of the press.
    4: Set pop. 1, characterized in that the coating means are mounted with a possibility of reciprocating movement in the direction of movement of the tapes of the finishing press.
