Description

Die Erfindung betrifft ein Verfahren zum Erstellen mehrschichtiger, aus einzelnen Brettern aufgebauter Paneele nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for producing multilayer panels constructed from individual boards according to the preamble of claim 1.

Ein derartiges Verfahren ist aus DE 297 06 060 U1 bekannt. Dort ist eine Deckelnagelmaschine mit einem in der Höhe verstellbaren Arbeitstisch offenbart, auf dem Quer- und Deckbretter für die Weiterverarbeitung zu fertigen Holzpaletten miteinander vernagelt werden. Hier werden die Quer- und Deckbretter fertigt ausgerichtet in eine Magazinschablone eingeschoben und dort über einen Nagelvorgang miteinander verbunden. Eine Messung der Bretter findet jedoch nicht statt.Such a procedure is over DE 297 06 060 U1 known. There, a lid nail machine with a height-adjustable work table is disclosed, are boarded together on the cross and cover boards for further processing into finished wooden pallets. Here, the cross and cover boards are manufactured aligned inserted into a magazine template and connected there via a nail process. However, a measurement of the boards does not take place.

In der EP 1 097 791 A2 ist ein Verfahren zur Steuerung eines Montagezyklus einer Rahmenmontagemasehine offenbart, bei dem der Querschnitt der zu montierenden Rahmenbauteile mit Hilfe eines Scanners erfasst und die Position der montierenden Rahmenbauteile berechnet wird.In the EP 1 097 791 A2 discloses a method of controlling a mounting cycle of a frame mounting system in which the cross section of the frame members to be mounted is detected by means of a scanner and the position of the mounting frame members is calculated.

Aufgabe der Erfindung ist es, ein Verfahren der eingangs genannten Art zu schaffen, bei dem die Erstellung mehrschichtiger Paneele auf einfache und effiziente Weise erfolgen kann.The object of the invention is to provide a method of the type mentioned, in which the creation of multi-layer panels can be done in a simple and efficient manner.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruch 1 gelöst. Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a method having the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Insbesondere als sehr vorteilhaft hat es sich erwiesen, wenn als Zuführung eine Vorfertigungseinrichtung vorgesehen ist.In particular, it has proved to be very advantageous if a prefabrication device is provided as the feed.

Dabei wird auf einem gesonderten Werktisch/Maschine wenigstens ein Teil einer Lage vorgefertigt und dann dieser vorgefertigte Teil an die erfindungsgemäße Vorrichtung übergeben.At least part of a layer is prefabricated on a separate workbench / machine and then transferred this prefabricated part of the inventive device.

Es hat sich auch als sehr vorteilhaft erwiesen, wenn wenigstens eine Transporteinrichtung vorgesehen ist, welche zu verarbeitende Bretter an die Verarbeitungsposition zu bringen vermag. Dabei kann als Transportvorrichtung ein Schieber vorgesehen sein.It has also proved to be very advantageous if at least one transport device is provided which is able to bring boards to be processed to the processing position. In this case, a slider may be provided as a transport device.

Ein Schieber, der auch als Schieblineal ausgebildet sein kann, vermag Bretter auf einfache Art und Weise an die Verarbeitungsposition zu bringen. Die Bretter können dabei über die vorangehende Lage geschoben oder auch im Abstand darüber hinweg transportiert werden.A slider, which can also be designed as a sliding rule, can bring boards in a simple manner to the processing position. The boards can be pushed over the previous position or transported in the distance over it.

Eine Meßeinrichtung für die Breite und/oder Position der zu verarbeitenden Bretter ist vorgesehen.A measuring device for the width and / or position of the boards to be processed is provided.

Hierdurch können die Nagelpositionen exakt berechnet werden.This allows the nail positions to be calculated exactly.

Vorteilhaft ist es auch, wenn wenigstens eine horizontale und/oder vertikale Anpresseinrichtung vorgesehen ist.It is also advantageous if at least one horizontal and / or vertical pressing device is provided.

Dadurch werden die Bretter an das zuvor verarbeitete Brett und die zuvor verarbeitete Lage eng angelegt, wodurch eine hohe Stabilität des fertigen Paneels erreicht werden kann.As a result, the boards are tightly applied to the previously processed board and the previously processed layer, whereby a high stability of the finished panel can be achieved.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt auch darin, daß die Anpresseinrichtung zweigeteilt ausgebildet ist, wobei der zweite Teil der Anpressvorrichtung als Vorlaufrolle ausgebildet sein kann.A further advantageous embodiment of the invention is also in that the pressing device is formed in two parts, wherein the second part of the pressing device may be formed as a feed roller.

Hiermit wird sichergestellt, daß das Brett auf seiner gesamten Länge am vorhergehenden Brett anliegt und parallel dazu verläuft.This ensures that the board rests over its entire length on the previous board and runs parallel to it.

Wenigstens eine Nagelvorrichtung ist vorgesehen, wobei die Nagelvorrichtung dreh- und/oder kippbar gelagert sein kann.At least one nail device is provided, wherein the nail device can be rotatably and / or tiltably mounted.

Damit ist es zum Beispiel möglich, mit nur einer Nagelvorrichtung sowohl Nagelreihen in Längs- als auch in Querrichtung anzubringen.This makes it possible, for example, to attach both nail rows in the longitudinal and in the transverse direction with only one nail device.

Mit einer Nagelvorrichtung können die einzelnen Bretter einfach und schnell, aber dennoch haltbar miteinander verbunden werden. Die Möglichkeit der Schrägstellung der Nägel bewirkt einen nochmals verbesserten Kraftlinienverlauf im fertigen Paneel. So können Paneele für besondere Einsatzzwecke gefertigt werden.With a nail device, the individual boards can be easily and quickly, yet durable connected to each other. The possibility of tilting the nails causes a further improved line of force in the finished panel. So panels can be made for special purposes.

Wenn eine verfahrbare Traverse vorgesehen ist, an welcher die Nagelvorrichtung gelagert ist und verfahren werden kann, kann auf einfache Art und Weise jede beliebige Position des Arbeitstisches angefahren werden.If a movable traverse is provided, on which the nailing device is mounted and can be moved, can be approached in a simple manner any position of the work table.

Dabei hat es sich als sehr vorteilhaft erwiesen, wenn zwei oder mehr Nagelvorrichtungen vorgesehen sind, wodurch in einem Durchlauf eine entsprechende Anzahl an Nagelreihen angebracht werden kann. Die Nagelreihen können versetzt zueinander angeordnet sein.It has proved to be very advantageous if two or more nail devices are provided, whereby a corresponding number of nail rows can be mounted in a single pass. The nail rows can be arranged offset from one another.

Desweiteren kann die Nagelvorrichtung mit einem oder mehreren Nagelmagazinen versehen sein. Die Nägel können mittels einer z.B. pneumatischen Transportvorrichtung der Nagelvorrichtung zugeführt werden. Zusätzlich kann auch eine Vereinzelungsvorrichtung vorgesehen sein, welche größere Mengen von Nägeln sortiert, ausrichtet und vereinzelt.
Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt auch dann vor, wenn der Arbeitstisch mittels wenigstens eines Hydraulik- oder Pneumatikzylinders in der Höhe verstellbar ausgebildet ist.
Furthermore, the nail device may be provided with one or more nail magazines. The nails can be fed by means of a pneumatic transport device of the nail device. In addition, too a separating device may be provided which sorts, aligns and isolates larger quantities of nails.
A further advantageous embodiment of the invention is also present when the work table is adjustable in height by means of at least one hydraulic or pneumatic cylinder.

Damit kann der Arbeitstisch an die jeweils schon gefertigte Dicke des Paneels angepasst werden, wodurch die Arbeitshöhe während der gesamten Fertigung gleich bleibt.Thus, the work table can be adapted to the already manufactured thickness of the panel, whereby the working height remains the same throughout the production.

Dabei kann im Bereich der Ecken des Arbeitstisches jeweils eine Höhenverstellung angeordnet sein, welche einstellbar miteinander verbunden sein können.In this case, in each case a height adjustment can be arranged in the region of the corners of the work table, which can be adjustably connected to each other.

Hierdurch kann die Höhe des Arbeitstisches mittels eines einzigen Hydraulik/Pneumatikzylinders verstellt werden, wobei trotzdem sichergestellt ist, daß der Tisch gleichmässig hoch ist.In this way, the height of the work table can be adjusted by means of a single hydraulic / pneumatic cylinder, while still ensuring that the table is uniformly high.

Eine weitere sehr vorteilhafte Ausgestaltung der Erfindung liegt auch darin, daß unterhalb des Arbeitstisches wenigstens eine Rolle oder eine Gleitschiene vorgesehen ist, wobei die Rolle antreibbar ausgebildet sein kann.Another very advantageous embodiment of the invention is also the fact that below the work table at least one roller or a slide rail is provided, wherein the roller can be designed to be drivable.

Auf diesen kann das fertige Paneel aus der Vorrichtung herausgeschoben werden, wenn der Arbeitstisch entsprechend weit abgesenkt wird.On these, the finished panel can be pushed out of the device when the work table is lowered accordingly far.

Als sehr vorteilhaft hat es sich auch erwiesen, wenn der Vorrichtung eine Einrichtung zum Falzschneiden vorgeordnet und/oder eine Einrichtung zum Bearbeiten der erstellten Paneele nachgeordnet istIt has also proven to be very advantageous if the device is preceded by a device for folding cutting and / or a device for processing the created panels is arranged downstream

Eine weitere vorteilhafte Fortbildung der Erfindung liegt auch darin, daß die Bretter wenigstens auf einer Seite Nuten, Einkerbungen und/oder Einschnitte aufweisen, die sich in Längs oder Querrichtung erstrecken.A further advantageous development of the invention lies in the fact that the boards have at least on one side grooves, notches and / or incisions extending in the longitudinal or transverse direction.

Hierdurch werden Lufträume gebildet, die eine sehr gute Wärmeisolation begründen. Durch entsprechend kleine Abmessungen der Nuten od. dgl. wird zudem wirkungsvoll ein Wärmetransport durch Konvektion verhindertAs a result, air spaces are formed, which justify a very good heat insulation. By correspondingly small dimensions of the grooves od. Like. Effective heat transport is prevented by convection

Es ist auch sehr vorteilhaft, wenn innerhalb des Paneels wenigstens eine Lage eines Dämmmaterials vorgesehen sein kann.It is also very advantageous if at least one layer of insulating material can be provided within the panel.

Durch ein Dämmmaterial kann eine Dampf-, Wind- oder Feuchtigkeitssperre realisiert werden. Auch eine zusätzliche Wärmedämmung kann vorgesehen sein. Als Wärmedämmung bietet sich als natürliches Dämmmaterial Schafwolle oder Weichholzdämmung an.By insulating a vapor, wind or moisture barrier can be realized. An additional thermal insulation can also be provided. For thermal insulation, natural wool or sheep softwood insulation can be used.

Die Paneele können aus günstigem "Abfallholz" gefertigt sein, worunter Brettabschnitte, Weichholzbretter und Schwartenbretter zu verstehen sind. Die äußersten Lagen der Paneele können aus Edelholz oder furniertem Holz gefertigt sein.The panels can be made of cheap "waste wood", which is to be understood as board sections, softwood boards and rafter boards. The outermost layers of the panels can be made of precious wood or veneered wood.

Mit 1 ist in Fig. 1 eine Vorrichtung zum Zusanunenfügen mehrschichtiger Paneele bezeichnet. Auf einem Arbeitstisch 2 werden einzelne Bretter 3 parallel zueinander und dicht aneinander abgelegt. Eine Spannvorrichtung 4, die am Arbeitstisch angelenkt ist, hält die Bretter 3 eng aneinander. Auf diese erste Bretterlage werden in Querrichtung weitere Bretter 5 aufgebracht, die ebenso wie die Bretter 3 der ersten Lage auf einen Vorlagetisch 6 aufgelegt werden und dann mittels eines Lineals 71 an die zu bearbeitende Position transportiert und dort durch Verkippung des Lineals 71 abgeworfen werden. Die Bretter 5 werden auf dem Vorlagetisch 6 an einem Anschlag 8 ausgerichtet. Hierzu können die Bretter 5 mittels einer Einzugsrolle 61 auf den Vorlagetisch 6 gezogen werden und nach vollständigem Einzug rückwärts gegen den Anschlag 8 transportiert werden. Denkbar ist aber auch, daß die Bretter 5 einem nicht dargestellten Magazin entnommen werden, oder daß mehrere bereits zusammengefügte Bretter zusammen an die Arbeitsposition verbracht werden. Anstatt eines Lineals 71 kann auch ein Greifer, ein Sauger oder ein Schieber 7 als Transporteinrichtung vorgesehen sein.With 1 is in Fig. 1 a device for Zusanunenfügen multilayer panels called. On a work table 2 individual boards 3 are stored parallel to each other and close together. A clamping device 4, which is hinged to the work table, keeps the boards 3 close together. On this first board position further boards 5 are applied in the transverse direction, which are placed as well as the boards 3 of the first layer on a feed table 6 and then transported by a ruler 71 to the position to be processed and dropped there by tilting the ruler 71. The boards 5 are aligned on the feed table 6 at a stop 8. For this purpose, the boards 5 can be pulled by means of a feed roller 61 on the feed table 6 and are transported after complete retraction backwards against the stop 8. It is also conceivable that the boards 5 are removed from a magazine, not shown, or that several already assembled boards are brought together to the working position. Instead of a ruler 71, a gripper, a sucker or a slider 7 may be provided as a transport device.

Ist das Brett an der Arbeitsposition angelangt, wird es mittels einer Spannvorrichtung 9 an das zuvor bearbeitete Brett angedrückt. Diese Spannvorrichtung 9 ist verschiebbar an einer an der Vorrichtung 1 verfahrbar gelagerten Traverse 10 befestigt. Damit ist jede beliebige Position des Arbeitstisches 2 anfahrbar. Mittels einer Vorlaufrolle 11 wird sichergestellt, daß das zu bearbeitende Brett auf seiner gesamten Länge am vorhergehenden Brett anliegt. Zusätzlich wird das zu bearbeitende Brett durch eine vertikale Spannvorrichtung 12, welche ebenfalls an der Traverse 10 gelagert ist an die vorhergehende Brettlage 3 angedrückt. Desweiteren wird mittels einer Meßeinrichtung die Breite des aktuellen Brettes 5 gemessen. Die Meßeinrichtung kann sowohl an der Traverse 10 als auch am Vorlagetisch 6 vorgesehen sein. Daraus werden unter Berücksichtigung der Brettbreiten der vorhergehenden Lage 3 die Positionen zum Vernageln der Bretter berechnet. Ein Nagler 13 welcher wiederum an der Traverse 10 befestigt ist, vernagelt das aktuelle Brett 5 mit Aluminium-, Eisen-, Holz-, Kunststoffnägeln/-stiften oder dergleichen.If the board has reached the working position, it is pressed by means of a tensioning device 9 to the previously edited board. This tensioning device 9 is slidably mounted on a traverse 10 movably mounted on the device 1. Thus, any position of the work table 2 can be approached. By means of a feed roller 11 ensures that the board to be machined rests on its entire length on the previous board. In addition, the board to be processed is pressed by a vertical tensioning device 12, which is also mounted on the traverse 10 to the previous board layer 3. Furthermore, the width of the current board 5 is measured by means of a measuring device. The measuring device can be provided both on the traverse 10 and on the feed table 6. From this, considering the board widths of the previous layer 3, the positions for nailing the boards are calculated. A nailer 13 which in turn is attached to the cross member 10, the current board 5 with aluminum, iron, wood, plastic nails / pins or the like nailed.

Es ist auch denkbar, daß zwei Nagler 13 an der Traverse 10 befestigt sind, die zusammen in einem Arbeitsgang zwei Nagelreihen anbringen. Die Nagelreihen können dabei versetzt zueinander sein. Es ist desweiteren auch denkbar, daß der eine der beiden Nagler 13 das vorhergehende Brett 5 und der andere das aktuelle Brett 5 vernagelt. Die beiden Nagler 13 können derart drehbar an der Traverse 10 befestigt sein, daß sie jeweils längs oder quer ausgerichtet werden können, je nachdem ob Längs- oder Querbretter 3 bzw. 5 verarbeitet werden sollen.It is also conceivable that two nailer 13 are attached to the cross member 10, which attach together two nail rows in one operation. The nail rows can be offset from each other. It is also conceivable that one of the two nailers 13 the previous board 5 and the other board 5 boarded up. The two nailer 13 may be rotatably mounted on the cross member 10 so that they can be aligned longitudinally or transversely, depending on whether longitudinal or transverse boards 3 and 5 are to be processed.

Am Nagler 13 kann ein nicht dargestelltes Vorratsmagazin für Nägel vorgesehen sein, welches auch als Sortier-, Ausricht- und Vereinzelungsvorrichtung für die Nägel ausgebildet sein kann. Es ist auch denkbar das Vorratsmagazin an den Rand der Vorrichtung 1 zu verlagern. Es kann dort besonders einfach mit Nägeln bestückt werden. Die Nägel können dann über einen Schlauch od. dgl. dem Nagler zugeführt werden. Die Nägel werden im Schlauch mittels Druckluft transportiert. Dabei ist es auch denkbar, daß am Nagler 13 ein weiteres Vorratsmagazin vorgesehen ist, welches vom ersten Vorratsmagazin aus mit Nägeln bestückt wird. So können auch mehrere Nagler 13 aus nur einem einzigen Vorratsmagazin mit Nägeln versorgt werden.At the nailer 13, an unrepresented storage magazine for nails may be provided, which may also be designed as a sorting, aligning and separating device for the nails. It is also conceivable to shift the storage magazine to the edge of the device 1. It can be equipped there very easily with nails. The nails can then be supplied via a hose or the like to the nailer. The nails are transported in the hose by means of compressed air. It is also conceivable that a further storage magazine is provided on the nailer 13, which is equipped with nails from the first storage magazine. Thus, several nailer 13 can be supplied from a single storage magazine with nails.

Nach Fertigstellung einer Brettlage wird der Arbeitstisch 2 um die Dicke der Lage 5 abgesenkt. Hierzu ist im Bereich der vier Ecken des Arbeitstisches 2 jeweils eine Höhenverstellung 14 vorgesehen, welche mittels Ketten 15 und Arbeitsbalken 16 miteinander verbunden sind. Am einen Arbeitsbalken 16 greift ein Hydraulikzylinder 17 an, welcher zentral die Höhe des Arbeitstisches 2 einzustellen vermag. Die Ketten 15 sind manuell einstellbar an den Arbeitsbalken 16 angelenkt, wodurch Fertigungstoleranzen ausgeglichen werden können. Es ist dabei aber auch denkbar, daß jeder Höhenverstellung ein eigener Arbeitszylinder 17 zugeordnet ist. Diese Zylinder 17 müssen dann aber so aufeinander abgestimmt werden, daß der Arbeitstisch 2 jeweils eine ausgerichtete Position einnimmt. Nach Aufbringen aller Holzlagen 3,5 wird der Arbeitstisch 2 so weit abgesenkt, daß das aus den Holzlagen gebildete fertige Paneel 18 auf Rollen 19 aufliegt und aus der Vorrichtung 1 herausgeschoben werden kann. Dabei ist es denkbar, daß auch Gleitschienen vorgesehen sind und daß mindestens eine Rolle 19 angetrieben ist. Das fertige Paneel 18 kann dann in einer weiteren, nicht dargestellten Bearbeitungsstation mit Ausschnitten 21, Einschnitten 22, Falzen 23 oder dergleichen versehen werden. Die Bretter 3 und 5 können vor Verarbeitung in der Vorrichtung 1 mit Falzen 24, Einschnitten 25, Fugen 26 oder dergleichen versehen werden. Werden Falzen 24 an den Seitenkanten der Bretter vorgesehen, wird dadurch eine dichte Verbindung zwischen den einzelnen Brettern erzielt. Andererseits erzeugen längs oder quer eingeschnittene Nuten 26 Luftkammern, die für eine Wärmeisolierung des gesamten Paneels 18 sorgen. Bei entsprechend kleiner Dimensionierung dieser Nuten wird auch ein Wärmetransport durch Konvektion wirkungsvoll verhindert.After completion of a board position of the work table 2 is lowered by the thickness of the layer 5. For this purpose, in each case a height adjustment 14 is provided in the region of the four corners of the work table 2, which are connected to each other by means of chains 15 and working beam 16. On a working beam 16 engages a hydraulic cylinder 17, which is able to centrally adjust the height of the work table 2. The chains 15 are manually adjustable hinged to the working beam 16, whereby manufacturing tolerances can be compensated. It is also conceivable that each height adjustment is associated with a separate working cylinder 17. However, these cylinders 17 must then be coordinated so that the work table 2 occupies an aligned position. After applying all layers of wood 3.5 of the work table 2 is lowered so far that the finished panel 18 formed from the wood layers rests on rollers 19 and are pushed out of the device 1 can. It is conceivable that slide rails are provided and that at least one roller 19 is driven. The finished panel 18 can then be provided in a further processing station, not shown, with cutouts 21, cuts 22, folds 23 or the like. The boards 3 and 5 can be provided with seams 26, grooves 26 or the like prior to processing in the device 1. If folds 24 are provided on the side edges of the boards, this results in a tight connection between the individual boards. On the other hand, longitudinally or transversely cut grooves 26 create air chambers that provide thermal insulation of the entire panel 18. With correspondingly smaller dimensions of these grooves, a heat transfer by convection is effectively prevented.

Größer dimensionierte Einschnitte 25 dienen zum Ausgleich von Spannungen, die sich durch Größenänderungen der Bretter unter anderem durch Temperaturschwankungen, Trockung und Schwund einstellen.Larger-sized cuts 25 are used to compensate for stresses that occur due to changes in size of the boards, among other things, by temperature fluctuations, drying and shrinkage.

Zusätzlich kann zwischen einzelnen Brettlagen eine Isolierschicht vorgesehen sein, welche aus einem Isoliermaterial zur Wärmedämmung, zur Windbrechung oder als Dampfsperre wirken kann. Es hat sich zur Wärmedämmung der Einsatz von Holzweichfaserplatten oder Schafwolle und zur Windbrechung der Einsatz von Folien und Papier bewährt. Folien können dabei diffusionsdicht aber auch diffusionsoffen für Wasserdampf ausgebildet sein.In addition, an insulating layer can be provided between individual board layers, which can act from an insulating material for thermal insulation, for wind breakage or as a vapor barrier. It has been proven for thermal insulation of the use of soft wood fiber boards or sheep's wool and wind breaking the use of films and paper. Films can be diffusion-proof but also vapor-permeable to water vapor.

Zusätzlich zum oben beschriebenen können weitere Spann- und Nagelvorrichtung an der Traverse 10 vorgesehen sein, wobei dann entweder mehrere gemeinsam ein einziges Brett bearbeiten oder jede für eine Brettrichtung (längs oder quer) vorgesehen ist.In addition to the above-described further tensioning and nailing device may be provided on the traverse 10, in which case either several together process a single board or each is provided for a boarding direction (longitudinal or transverse).

Zudem können die Nägel in einem vorgegebenen Abstand vom Brettrand vorgesehen werden.In addition, the nails can be provided at a predetermined distance from the edge of the board.

Die Nägel können auch relativ zu den Senkrechten der Bretter verkippt vernagelt werden.The nails can also be nailed tilted relative to the uprights of the boards.

Die gefertigten Paneele bestehen aus zwei oder mehr Lagen lagenweise gegeneinander verdrehter Bretter, wobei die Bretter einer einzelnen Lage jeweils aneinandergereiht nebeneinander zu liegen kommen. Als zu verarbeitende Bretter können alle Arten von Brettern herangezogen werden, inclusive Schwartenbrettern und dergleichen. Die Schwartenbretter können zumindest in einzelnen Lagen des Paneels vorgesehen sein.The manufactured panels consist of two or more layers of layers twisted against each other boards, the boards of a single layer each juxtaposed come to rest next to each other. As boards to be processed all types of boards can be used, including rafter boards and the like. The rafter boards can be provided at least in individual layers of the panel.

Das gesamte Paneel weist vorzugsweise eine Gesamtdicke zwischen 20 und 600mm, insbesondere zwischen 80 und 350mm auf.The entire panel preferably has a total thickness of between 20 and 600 mm, in particular between 80 and 350 mm.

Es ist desweiteren auch denkbar, daß wenigstens eine Oberfläche des Paneels mit einer Edelholzschicht versehen ist bzw. die Oberflächenschicht aus einem Edelholz gefertigt ist, wodurch sich besondere optische Wirkungen erzielen lassen.It is also conceivable that at least one surface of the panel is provided with a precious wood layer or the surface layer is made of a precious wood, which can achieve special visual effects.
