Abstract

1. A process for the production of a front panel of an article of furniture wherein a cover foil or a veneer is applied to an initially flat chipboard panel and thereafter the cover foil or the veneer is joined to the chipboard panel under pressure and with the application of heat, with simultaneous relieflike surface deformation of the chipboard panel, characterized in that the chipboard panel (11) is of a density of about 400 to 450 kg/m**3 and it is compacted during the joining and deformation operation.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Möbelfrontplatte, wobei auf eine zunächst ebene Spanplatte eine Deckfolie oder ein Furnier aufgelegt und danach unter Druck und Wärmezufuhr die Deckfolie oder das Furnier unter gleichzeitiger reliefartiger Oberflächenverformung der Spanplatte mit dieser verbunden wird.The present invention relates to a method for producing a furniture front panel, a cover sheet or a veneer being placed on an initially flat chipboard and then the cover sheet or the veneer being connected to the latter under pressure and heat while simultaneously relieving the surface of the chipboard in relief.

Bislang hat man bei der Anwendung des gattungsgemäßen Verfahrens Spanplatten von einer Dichte von ca. 550 bis 600 kg/m3 eingesetzt, also verhältnismäßig feste Spanplatten. Der Einsatz derartiger Materialgüten erschien zwingend notwendig, um der fertigen Möbelfrontplatte die erforderliche Schraubfestigkeit zu geben, das heißt, Beschlagteile aller Art hochbelastbar an einer derartigen Möbelfrontplatte anbringen zu können.So far, chipboard with a density of approx. 550 to 600 kg / m 3 has been used when using the generic method, that is to say relatively solid chipboard. The use of such material qualities appeared to be absolutely necessary in order to give the finished furniture front panel the required screw strength, that is to say it is possible to attach fittings of all kinds to such a furniture front panel with a high load capacity.

Als nachteilig hat sich dabei allerdings herausgestellt, daß die reliefartige Oberflächenverformung nur in relativ kleinen Grenzen möglich ist.It has turned out to be disadvantageous, however, that the relief-like surface deformation is only possible within relatively small limits.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art dahingehend weiterzuentwickeln, daß eine vergleichsweise tiefe reliefartige Oberflächenverformung ermöglicht wird und die fertige Möbelfrontplatte dennoch mechanisch hochbelastbar ist.The present invention has for its object to further develop a method of the generic type in such a way that a comparatively deep relief-like surface deformation is made possible and the finished furniture front panel is nevertheless mechanically highly resilient.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Spanplatte von einer Dichte von etwa 400 bis 450-kg/m3 verwendet und dieselbe während des Verbindungs- und Verformungsvorganges verdichtet wird.This object is achieved in that a particle board with a density of about 400 to 450 kg / m 3 is used and the same is compressed during the connection and deformation process.

Durch die Verwendung einer Spanplatte von einer Dichte von etwa 400 bis 450 kg/m3, also einem vergleichsweise weichen Material, wird eine verhältnismäßig tiefgehende reliefartige Oberflächenverformüng ermöglicht, ohne daß hierbei übermäßig hohe Drücke aufgebracht werden müssen. Durch die gleichzeitige Verdichtung der Spanplatte wird diese in sich derart verfestigt, daß alle mechanischen Anforderungen, die an eine fertige Möbelfrontplatte gestellt werden, erfüllbar sind.The use of a particle board with a density of approximately 400 to 450 kg / m 3 , that is to say a comparatively soft material, enables a relatively deep relief-like surface deformation without the need to apply excessively high pressures. The simultaneous compression of the particle board solidifies it in such a way that all mechanical requirements that are placed on a finished furniture front panel can be met.

Es hat sich herausgestellt, daß eine Verdichtung der Spanplatte auf etwa 70 bis 85 % ihres ursprünglichen Volumens sowohl möglich wie auch völlig ausreichend ist.It has been found that compaction of the particle board to about 70 to 85% of its original volume is both possible and completely sufficient.

Anhand der beigefügten Zeichnungen wird in folgenden das erfindungsgemäße Verfahren noch einmal erläutert.The method according to the invention is explained again in the following with reference to the attached drawings.

In den Zeichnungen zeigen

  • Fig. 1 eine mit reliefartiger Oberflächenverformung versehene Möbelfrontplatte in perspektivischer Darstellung,
  • Fig. 2 einen Teilschnitt nach der Linie 11 - 11 in Fig. 1,
  • Fig. 3 eine Teilansicht einer weiteren Möbelfrontplatte,
  • Fig. 4 einen Schnitt durch die Möbelfrontplatte gemäß Fig. 3,
  • Fig. 5 eine Teilansicht einer weiteren Möbelfrontplatte,
  • Fig. 6 einen Teilschnitt nach der Linie VI - VI in Fig. 5.
Show in the drawings
  • 1 is a perspective view of a furniture front panel provided with relief-like surface deformation,
  • 2 shows a partial section along the line 11-11 in FIG. 1,
  • 3 shows a partial view of a further furniture front panel,
  • 4 shows a section through the furniture front panel according to FIG. 3,
  • 5 is a partial view of a further furniture front panel,
  • 6 shows a partial section along the line VI-VI in FIG. 5.

Die in Fig. 1 dargestellte und insgesamt mit dem Bezugszeichen 10 versehene Möbelfrontplatte besteht, was insbesondere aus Fig. 2 hervorgeht, aus einer Spanplatte 11 und einer auf diese Spanplatte 11 aufgebrachten Deckfolie 12. Statt einer Deckfolie 12 kann selbstverständlich auch ein Furnier aufgebracht sein.The furniture front panel shown in FIG. 1 and provided overall with the reference number 10 consists, as can be seen particularly from FIG. 2, of a particle board 11 and a cover film 12 applied to this particle board 11. Instead of a cover film 12, a veneer can of course also be applied.

Die Möbelfrontplatte 10 ist auf einer Seite, nämlich auf derjenigen, auf der die Deckfolie 12 aufgebracht ist, mit einer reliefartigen Oberflächenverformung versehen. Im dargestellten Ausführungsbeispiel handelt es sich dabei um parallel zueinander verlaufende Rillen 13. Statt einer derartigen Verformung können selbstverständlich auch andere Muster gewählt werden.The furniture front panel 10 is provided with a relief-like surface deformation on one side, namely on that on which the cover film 12 is applied. In the exemplary embodiment shown, these are grooves 13 running parallel to one another. Instead of such a deformation, other patterns can of course also be selected.

Die Möbelfrontplatte 10 ist in der Weise hergestellt, daß auf die zunächst flachebene Spanplatte 11 die Deckfolie 12 aufgebracht worden ist. In einer entsprechenden Form ist danach unter entsprechendem Druck und unter Wärmezufuhr die Deckfolie 12 mit der Spanplatte 11 unter Einbringung der reliefartigen Oberflächenverformung verbunden worden. Während des Verbindungs- und Verformungsvorganges ist die Spanplatte 11 gleichzeitig verdichtet worden, und zwar etwa auf 70 bis 85 % ihres ursprünglichen Volumens.The furniture front panel 10 is manufactured in such a way that the cover sheet 12 has been applied to the initially flat-level chipboard 11. In a corresponding form, the cover film 12 was then connected to the chipboard 11 with the introduction of the relief-like surface deformation under appropriate pressure and with the application of heat. During the connection and deformation process, the particle board 11 was compressed at the same time, namely to about 70 to 85% of its original volume.

Durch die strichpunktierten Linien in den Fig. 1 und 2 soll angedeutet sein, daß die Spanplatte 11 vor dem Verbindungs- und Verformungsvorgang beträchtlich dicker war als nach dem Verbindungs- und Verformungsvorgang.The dash-dotted lines in FIGS. 1 and 2 are intended to indicate that the chipboard 11 was considerably thicker before the connection and deformation process than after the connection and deformation process.

Es ist eine Spanplatte 11 verwendet worden, die vor dem Verdichtungsvorgang eine Dichte von ca. 400 bis 450 kg/m3 aufwies. Nach dem Verdichtungsvorgang beträgt die Dichte der Spanplatte 11 etwa 550 bis 600 kg/m3 und weist damit die erforderliche mechanische Festigkeit auf.A particle board 11 was used which had a density of approximately 400 to 450 kg / m 3 before the compression process. After the compression process, the density of the particle board 11 is approximately 550 to 600 kg / m 3 and thus has the required mechanical strength.

In den Fig. 3 bis 6 sind weitere Möbelfrontplatten 10 dargestellt, die aufzeigen, daß mit dem erfindungsgemäßen Verfahren die unterschiedlichsten reliefartigen Oberflächenverformungen durchgeführt werden können.3 to 6 show further furniture front panels 10, which show that the most varied relief-like surface deformations can be carried out with the method according to the invention.
