Description

Decks for panels and profiles panels for the manufacture of furniture, Doors, walls and other construction elements are known to consist of a core, also called middle position, and the so-called.

Outside decks. The core can be made of stick or stick-glued solid wood, made of chips or fibers wetted with binding agents, produced in the pressing process, exist. These plate cores or middle layers are with or without interposition a barrier layer with one- or two-layer veneer decks glued. Thereon the opaque or transparent exterior comes in the form of known lacquers or Synthetic resin dispersions.

The endeavors of the furniture manufacturing and wood processing industry go towards the natural product wood in its unrestricted naturalness demonstrate ; this is the only way that the rich expression of this noble material comes into its own come into its own. Maintaining the warmth and comfort is a task that always is and is placed everywhere and which this inventive idea also pursues.

The protection of a bolt-veneered surface against mechanical damage can only be achieved to a limited extent. A protection against activity and similar aggressive Influences can, however, already be achieved by known, relatively simple processes. It is understandable when attempts are made to refine this surface protection more and more, by making the connection to the wooden surface as intense as possible will. The so-called Polyester lacquer process with several layers of application and in between horizontal grinding operations has brought considerable progress, but it is time consuming and costly. The lamination process that has recently been used, in particular with so-called thermoplastic but transparent foils, like PVC, Polyethylene, etc. has advantages and disadvantages at the same time.

The advantages are that at the same time the edges in the common procedures, while the disadvantage is that that the impact, pressure and scratch resistance is only limited.

The experiments have shown and from the test results confirms that for the durability of the wood surface coating u. a. The decisive factor is how far the moisture present in the wood is determined and controlled will. Plate cores were made under the best climatic conditions with accordingly Glued to dried visible veneers and immediately, without the ingress of moisture could, provided with a synthetic resin layer. After a certain storage time showed sucked themselves anyway. Hairline cracks. It follows that it is necessary to have the To limit moisture to the lowest possible volume.

According to the invention it is therefore proposed that the surface or. Exposed veneer to be covered on one side with a metal or insulating film. This metal or insulating film has the function of blocking moisture and heat on the back or support side to act.

Appropriately, plate decks can be manufactured so that between 2 veneers, the fibers of which are the same or arranged at a right angle are, a metal or insulating film is put on one or both sides beforehand provided with a suitable adhesive and using the pressing process pressed together by pressure and / or heat to form a composite deck similar to plywood will. Depending on the nature of the panel core or the panel middle layer, these sucked

Decks with one, two or more layers, similar to the plywood process, getting produced. According to the invention, however, care must be taken that the metal or Insulation film as close as possible behind the first, d. b. facing the line of sight Veneer layer, is arranged.

According to the invention it is achieved that exposed veneer surfaces can be produced in one working press cycle. Synthetic resin films are suitable for this based on melamine-formaldehyde, which after appropriate condensation a result in good surface hardness. But non-hardening plastics, such as polyvinyl chloride, polyvinyl acetate or similar. be used. The choice of plastics depends on the demands made on the surface in the respective area of application be asked.

When using transparent synthetic resins in the form of liquid application or foils is achieved that the advantages of wood in their complex effect remain ; But plastics with colored pigments can also be applied will. According to the invention, the moisture control and management is carried out by Interposition of the metal or insulating film to the lowest possible mass, depending limited by the thickness of the exposed veneer and thus made easier. The influences which have so far been accepted due to moisture from the core of the middle layer had to are turned off because of the shift of moisture in the carrier material is present, can no longer affect the top veneer.

According to the invention it is proposed that the production of the one or multilayer plate decks, as described above, with simultaneous lamination the visible surface is done in the press-and-press process. Usually metal shim plates are used used, which have a smooth surface.

This surface can be polished or matted; corresponding this creates a high-gloss or matt appearance on the synthetic resin-laminated surface achieved.

The metal shim plate can also be used to achieve an interaction be treated with a high gloss and matt finish. You can use stripes, diamonds, rhombuses or figures so by changing the glossy or matt treatment of the sheet metal insert the Veneer synthetic resin surface can be achieved. The shim sheet, preferably on attached to the visible side of the deck to be produced, but can also be milled, for example in the thickness of the usual visible veneers, in the form of stripes, diamonds, rhombuses or figures are provided. According to these millings, veneers are made in Shape of stripes, diamonds, rhombuses or figures and punched into the millings of the insert plate inserted; beforehand, the plastic material intended for the casing is used Applied or inserted in the form of foils or liquid resin.

An attractive effect of the deck is achieved simply by that the supplementary sheets, whether flat or milled, optionally and alternately in depth or heightening are matted or polished, as these effects are also reflected in the plastic lamination result.

For the last method according to the invention it has been shown in tests that that it is advisable to have 2 veneer thicknesses with the interposition of gluing a metal or insulating film in 2 different colors to connect with each other. So it is possible, after cutting open or punching out, alternating light and dark To achieve surface effect.

According to the invention it is also provided that, for example, composite panels are produced in such a way that a cover veneer is applied to a fiber mat made of matted or glued wood or plant fibers with the interposition of the metal or insulating film. A plastic foam body can also be used instead of the fiber mat. According to the invention it is of course also possible that instead of the veneers z. B. a thin fiber mat is used when lamination with decorative film. Here, too, remains inven- important that between this surface fiber matt and the carrier body the metal-offfer insulating film is interposed.

It should be noted that the structure of the veneer decks, whether one or more layers, whether wood veneer or fiber mat, for the individual layers is used, depends on which particular strength is required.

That way, decks can be factory-made in one place and finally made in one place Point of use can be further processed.

FIG. 1 of the drawing shows an exemplary embodiment according to the invention on a greatly enlarged scale by adding a peeled or sliced wood veneer is covered in an appropriate thickness with a metal or insulating film.

FIG. 2 shows 2 thicknesses of veneer with a metal or metal layer in between Insulating film.

FIG. 3 shows a veneer covered with metal or insulating film which a veneer strip (a) is arranged so that it fits into the recess (b) of the Beilagenbbches (c) fits in.
