    The invention relates to materials used as cladding, in particular to laminated tapes, and is intended for cladding building elements made of simple wood material, particle boards, etc.
    Closest to the invention to the technical essence and the achieved result is a laminated tape consisting of a base and a decorative layer. The base is made of unplasticized polyvinyl chloride and provided with a decorative seal imitating f17 wood.
    Laminated tape is made by a method that includes gluing the base and the decorative layer.
    The said laminated tape, due to its constructive peculiarity, often cannot be used for cladding where cladding from natural wood is required, since natural wood veneer is not in the form of endless tapes due to its limited length of tree trunk.
    The aim of the invention is to provide a seamless lining of building elements.
    This goal is achieved by the fact that in a layered tape consisting of a base made of synthetic CMO.PY and a decorative layer, polyvinyl chloride or is used as a synthetic resin. poly-. ethylene terephthalate, and the decorative layer is sewn from natural wood tap, the texture of which is directed
    10 along the tape.
    Such a laminated tape can be made by a method consisting in sticking a layer of natural wood veneer with a synthetic resin base, cutting the resulting laminate into separate parts, joining them into a laminated tape so that the texture of the veneer is directed along the laminated flax20 you, and weld the jagged butt joints.
    Polyurethane glue or composite glue is used as glue.
    25 polyester.
    FIG. 1-5 schematically depicts individual techniques for making an endless laminated tape. FIG. 6 and 7 - the use of an endless layer of tape for facing a profile.

    , rfSSs -; FIG. 1 shows the foil 1 and natural wood, obtained by cutting B as the so-called microfaners. The width of the foil made of natural wood in this case corresponds to the length of the trunk of the cut wood, and the direction of texture 2 passes transversely to the longitudinal stretch of foil 1. Foil 1 of natural wood is not suitable for facing an endless way of profiles or other load-bearing plates, because the band tape of natural wood in the longitudinal course cannot be edged due to the danger of fracture of wood foil due to the transverse texture 2. Therefore, foil 1 is made of natural wood when using a layer of glue 4 combined with the carrier foil 3 in the composite foil 5, as shown schematically in FIG. 2. However, this multilayer foil 5 is still not suitable for endless upholstery because the direction of the texture 2 is transverse to the longitudinal stretch of the multilayer foil. As shown in FIG. 3, the multi-layered foil 5 is divided into sections 6 or cut, for example, along cut lines 7. These sections are then along both edges running transversely to the direction of texture 2, which are serrated as seen in FIG. 4. In this connection, it should be pointed out that natural wood foil 1 cannot be made serrated due to the lack of sufficient rigidity and intrinsic strength. Only provided in accordance with FIG. 2, the bond permits the use of teeth or spikes. The teeth. 8 according to FIG. 4 may also have a different look. In addition, not separate sections b can be provided with teeth or spikes, but multilayered foil 5 before cutting it into separate sections along edges, passage 1 x transversely to texture direction 2. Then the notched areas are rotated in a plane by 90 and continuously connected as shown in FIG. 5. Butt points 9 without further addition of auxiliary medium are subjected to thermal welding, and no thickening of the weld is observed. Particularly advantageous was the use of high-frequency welding or thermo-pulse welding. The edges of the teeth 8 along the joint point 9 without the use of impurities are homogeneously joined, and a completely smooth joint without an overlap occurs. At the butt-place, the carrier foil is welded, a layer of glue 4 is activated, and the glue is pressed in small quantities under the pressure of the welding medium into the seams of the teeth of natural wood. An infinite multilayer is obtained, the tape 10, with which the texture 2 of natural wood foils is directed along a longitudinal stretch of the multilayer tape. Now, the multilayer tape 10 can be used for endless covering of profiles, because in the longitudinal stretch of the multilayer tape, i.e.; parallel to texture direction 2, it can be edged. Multilayer tape 10 can be wound into a roll, as the material of the foil carrier provides: sufficient elasticity and prevents fracture of foil from natural wood. FIG. 7 in cross-section is represented by a profile 11, forming, for example, the drawer frame. Profile 11 consists of a simple wood-based panel, which should be veneered from natural wood. A multilayer tape 10 is used for this. While in FIG. 1-5 schematically and on a reduced scale, the preparation of a multi-layer tape 10 is shown; FIG. 6 and 7. A much larger and more natural scale is shown. The multilayer tape You use an endless covering profile 11 on the side formed by the carrier foil 3 with grooves 12. The grooves 12 run parallel to the direction of texture 2 in the longitudinal stretch of the multilayer tape 10. After the grooves have been provided the multilayer tape 10 through the roller devices and the pressure rollers are brought to the Ne profile and are lined with it. The adhesive bond between the profile 11 of the multilayer tape 10 can be carried out, for example, with glue, which is preliminarily applied to the profile 11 from the external side. In Figs 6 and 7, the initial part 10a of the multilayer tape is marked, due to which the profiling of the verbose tape 10 provided for facing is visible. With the help of the proposed multilayer material, it is possible to veneer, coat the profiles, plates, etc. A foil of natural wood in an endless way to produce products suitable for various purposes, which until now could not be made. The decorative foil is made of natural wood, which is glued to a thermally welded, thermoplastic plastic film. Directed (1e foil textures of natural wood preferably run along the proposed multilayer tape. Thus, the multilayer tape is made of separate, joined and welded at the butt joints. The butt holes are preferably made notched. Since the butt of the natural wood is not welded, It is foreseen to use an adhesive activated in a high-frequency field as an adhesive layer. Due to this, when foils are welded by high-frequency pulses At the junction points of the multilayer tape, by activating the glue, natural foil foil along the edges of the teeth can be glued together.
    Consequently, according to the invention, natural wood foils are applied to carrier foils made of plastic and, in this form, are used for endless covering of chipboard profiles, etc. Due to this, it is possible to use for endless plating not only imitation of wood on the basis of plastic films as seals, but also to manufacture building elements revetted with endless whole ribbon of natural wood.
    The proposed method of making a laminated tape consisting of a plastic foil carrier and a decorative foil is characterized in that a natural wood foil is used as a decorative foil, which is bonded with glue to yokite foil using an adhesive. Then, segments are made of multilayer foil, which along edges extending transversely to the direction of the texture of natural wood foil are continuously connected into an endless multilayer tape and the butt points are thermoformed, for example, by high-frequency welding or by thermal pulses. In this case, according to the invention, the use of natural wood foil, lime as a microfaner, which is obtained by peeling veneer, is envisaged. In this wood foil, the wood texture is applied to the longitudinal stretch of the film tape of valuable wood obtained by cutting. The width of foil made of real wood depends on the length of the trunk of the tree being cut. Similar endless foil made of macrofanner or real wood is not suitable for endless profiles, because the wood texture is transverse to the longitudinal stretch of the foil and, therefore, it is necessary to turn the foil longitudinally because it is transverse to the texture. with the danger of breaking the wood.
    Consequently, there is a need for the manufacture of film tape from microfaners, the texture of which runs parallel to the film tape. This problem is solved by the fact that the foil

    From real wood, a layer of glue or reinforcement adhesion is applied to the carrier foil of a welded, thermoplastic plastic. At the same time, it is possible to apply a foil made of natural wood to sections of the foil carrier, the length of which corresponds to the width of the foil carrier, with an offset of 90 in order that the texture direction of the sections of the present wood passes
    0 along the film tape. In order to achieve a perfect transition-pattern at the butt points of the sites, it is necessary to rotate 180 each longitudinally over the second portion.
    5 However, this does not solve the problem of closing the butt spots in the natural wood zone. Therefore, it is preferable to continuously connect a natural wood tape film to a carrier tape, with the texture direction first running across the multi-layer tape.
    The first multi-layer tape is then used to make sections of the desired dimensions, which are continuously connected in
    5 endless multilayer tape with the direction of the texture of the foil of natural wood in the longitudinal stretch. Then without the addition of a welding additive or other bonding agents.
    0 they are thermally and seamlessly joined at butt joints. In this case, the butt points are homogeneously joined, namely by welding the carrier foil, and a completely smooth
    5 butt-joint without overlap, overlap or gap. Thus, the pro-fooling of the carrier foil makes it possible to make from real wood in the form of endless ribbons or strips, direction; wood textures which
    0 parallel to the longitudinal stretch of the tape or strip.
    Since a natural wood foil in the joint zone cannot be directly joined, an additional adhesive action is directly provided with an adhesive layer. Therefore, it is preferable to use an adhesive activated in the high-frequency field, which simultaneously with the high-frequency welding
    0 is activated and, due to welding pressure, small quantities are pressed into the butt spots of the foil made of natural wood, ensuring its gluing along the edges. but
    5 glue should not penetrate to the surface of the multilayer tape.
    According to a preferred embodiment, the foil textures of natural wood arranged transversely to one another and transversely to the direction of the texture are made of serrated or spiked sections of natural wood. The cut lengths thus made are then connected. Homogeneous

    5, the connection is achieved by welding the carrier foil in the joint area, the natural wood foil being seamlessly and seamlessly embedded through the glue. It is desirable to use wood foil from microfaners with a thickness of preferably 0.1 - 0.3 mm. According to the first method, using a glue, for example, on the basis of polyurethane, nitrile rubber, PvAc or polyester, the foil is applied on solid wood, for example, by passing through a pair of rolls. The application of glue can be carried out either directly prior to the connection of the foil carrier with a foil of real wood, or the glue can be worn on one foil first and then activated by heat at the beginning of the connection. The thickness of the adhesive layer is 0.01 and 0.1 mm. Polyvinyl chloride based thermoplastic weldable plastics, preferably hardened or resistant PVC, acryl-butadiene-styrene, polystyrene, polyethylene terephthalate, polycarbonate, polyamide, styrene-acrylonitrile-copolymer, and the foil has a thickness of 0.1%, are foil-resistant. mm, preferably 0.1 - 0.4 mm. From the combined carrier foil and natural wood foil with the texture direction transversely to the longitudinal axis of the foil, the proposed length of the predetermined length is cut using the LM method and then preferably on the edges transverse to the texture direction, supply teeth and push each other. The technique of making teeth on plywood of solid wood, which are then inserted into each other, is already known. However, according to the invention, foil made of natural wood is used because of its small thickness However, due to this, insufficient stiffness and intrinsic strength cannot be made serrated. Only its connection with the carrier foil ensures that the teeth are made and can be joined into endless multilayer sheets. Flawless butt spots are achieved by thermal welding by high-frequency or thermal pulses of the carrier foil, and, as a rule, the jagged edges of the foil of real wood are additionally glued to each other by activation of the adhesive layer during the welding process. The infinite multilayer tape thus made can be provided with grooves on the side of the carrier foil in order to provide 1 lot covering at the corners of the profiles with endless facing. Preferably, the proposed endless multilayer tape with a foil of real wood, the texture of which also extends over the length of the multilayer tape, is used for endless lining of slabs or profiles, such as chipboard, preferably for furniture production, interior decoration. Example. An endless walnut veneer with a thickness of 150 microns is passed between a pair of rolls between the two, and it is glued to a 0.3 mm thick PVC base using polyurethane glue. In this case, the adhesive layer has a thickness of 0.2 mm. The resulting layered structure is cut into lengths of 1200 x 200 mm, on the narrow edges of which teeth are made 35 mm long, spaced 10 mm from each other. Then, the nicked edges of the segments are connected into an endless belt by welding under pressure of 12 kgf / cm for 2 s using a high-quality welding machine 12.kV. Example 2. Example 1 is repeated, with the difference that an endless birch wood veneer of 100 microns thickness and a 0.4 km thick polyethylene terephthalate substrate are used. The base is bonded to the veneer with polyester-based glue. The thickness of the adhesive layer is 0.3 mm. The resulting layered structure is cut into segments of 1200 X 50 mm in size. The main property of a laminated tape is its peeling strength, which is determined in the following way. Strips of an endless belt in examples 1 and 2 wide 5 cm put on the roll with a girth angle of 180 °. With the subsequent roll-off from the roll, the strength of the strips for peeling is determined using a knife. It is 9 and 9.3 kgf, respectively. On a chipboard with a length of 1 m and a thickness of 0.5 cm, paste the laminated tapes of Examples 1 and 2, respectively, and then determine the peeling strength using a knife Fixture. The strength is 6 kgf in both cases. The minimum peel strength exerted for wood-lined veneer products should be 2 kgf. Claims 1.
