Definitions
- the invention relates to a method for producing a wood panel with a structured surface, wherein a top layer of hardwood laminated on a support layer and the surface side is edited structuring.
- the invention is thus based on the object of structuring the surface of a wood panel by a processing method so that the wood panels can be structured without sacrificing strength in the region of a surface layer with a comparatively small amount of work.
- the invention achieves this object by laminating the cover layer with a moisture content of between 7 and 9%, preferably between 7.5 and 8.5%, onto the carrier layer before the surface of the cover layer is shaped by embossing.
- the moisture content of the top layer is set between 7 and 9%, so with the locally applied during embossing pressure on the top layer of wood fibers sufficient pressure for a permanent structuring without fiber break can be plastically deformed.
- a shaping structuring of the surface of the cover layer requires sufficient compressive strength of the carrier layer, which is true given in carrier layers of plywood and other wood materials with a corresponding compressive strength, but not in conventional carrier layers of needlewood. For this reason, when using carrier layers, an annual ring course of the needle wooden strips is to be provided transversely to the carrier layer.
- Such an annual ring course brings about an increase in the compressive strength of the carrier layer by more than twice.
- a Brinell hardness of about 30 to 35 N / mm 2 can be achieved by this measure.
- this Brinell hardness is about 40 N / mm 2 .
- This compressive strength of the carrier layer is sufficient to support the laminated cover layer in order to be able to emboss this surface layer of the cover layer permanently and gently with a groove of 30 to 150 N / mm, preferably 50 to 100 N / mm, based on a unit length.
- the surface of the cover layer can be oiled and waxed or painted in a conventional manner.
- the cover layer can be provided at the peripheral upper edge with a chamfer, the depth of which is greater than the depth of the surface embossing, so that the groove-like depressions leak in the region of these chamfers.
- the surface of the cover layer can be embossed with a flank angle of less than 75 °.
- the comparatively small angle of inclination of the flanks of the groove-like depressions also brings greater security against fiber breakage in the region of the flanks of the depressions.
- the cover layer can be pretreated before embossing groove-like depressions with an increasing the bending softness of the wood fibers agent.
- various surface treatments for example by oils, offer.
- embossing For performing the surface treatment of the cover layer by embossing is to provide a load-bearing support of the wood panel against the embossing, which is preferably applied by means of an embossing roll, which is provided with the negative shape of the groove-like depressions corresponding rib-like embossing approaches.
- This embossing roller opposite a driven counter-pressure roller is set with the aid of an actuating drive to the counter-pressure roller and has a diameter which corresponds to at most one third of the diameter of the counter-pressure roller. Because of this diameter ratio, the line pressure occurring when embossing the surface layer of the cover layer can be removed to a sufficient surface area of the carrier layer so as not to overload the carrier layer with respect to its compressive strength.
- the embossing roller can be aligned with respect to the structured top layer of the wood panel transversely to the conveying direction, it is recommended that the embossing roller to store in an axially movable carriage on the displaceably mounted guide the actuator for employment of the embossing roller engages the counter-pressure roller.
- the axial slide guide allows the respectively required alignment of the embossing roll transversely to the conveying direction the counter-pressure roller while the embossing force is applied via the carriage guide.
- the apparatus shown by way of example for producing a wooden panel with a structured surface has a frame 1 in which a counter-pressure roller 3 rotatably driven via a geared motor 2 is mounted fixed to the frame.
- the bearings of the counter-pressure roller are designated 4.
- vertical guide columns 5 are provided for an axial slide guide 6 in the frame 1, which can be displaced with the aid of actuators 7 along the guide columns 5.
- a carriage 8 is movable and detectable by means of terminals 9.
- an embossing roller 10 is mounted, by means of paired bearing rollers 11, so that embossing rollers 10 can be used with different sized bearing pin.
- a wooden plate 12 to be structured on the surface is conveyed through the machining gap between the embossing roller 10 and the counterpressure roller 3 with the aid of the driven counterpressure roller 3 with a corresponding action on the embossing roller 10.
- the wooden plate 12 is constructed of a carrier layer 13 of needle wood strips 14, on the one hand, a cover layer 15 of hardwood and on the other hand, a counter-layer 16, preferably made of softwood peeled veneers, are laminated. But this counter 16 can also omitted.
- the arrangement is made such that the needle wooden strips 14 have an annual ring course, which is aligned transversely to the carrier layer 13, as shown in the Fig. 3 was hinted at. This annual ring pattern results from the so-called side product when sawing a log.
- the cover layer 15 Before the cover layer 15 is applied to the carrier layer 13, the cover layer must be adjusted in terms of their moisture, resulting in a requirement for a minimum moisture of 7% and a maximum wood moisture of 9% as a prerequisite for a largely break-free embossing of the wood fibers.
- the double-ground wood plates 12 are then machined between the embossing roller 10 and the platen roller 3 according to the embossing projections of the embossing roller 10 by the embossing approaches are pressed with an adapted to the respective conditions embossing pressure in the surface layer of the cover layer 15, namely with a sufficient plastic Deformation of the wood fibers to obtain a permanent embossing in the form of groove-like depressions 17.
- the embossing approaches of the embossing roll 10 are formed in cross section so that an inclination of the flanks of these embossing approaches of at most 75 ° results. Such flank angles not only help to clean the cover layer 15 superficially, but also support the gentle deformation of the wood fibers in the area of the groove-like depressions 17.
- the peripheral upper edge of the cover layer 15 can be provided with a chamfer 18, as shown in the Fig. 4 is indicated.
- this chamfer 18 is formed with a depth greater than the depth of the groove-like recesses 17, the groove-like recesses 17 run out in the region of the chamfer 18, which can be provided with a corresponding coating to prevent the ingress of moisture in the region of the chamfers , The vulnerable to the ingress of moisture abutting surfaces of the cover layers 15 adjacent wood panels 12 cover each other, so that a moisture attack in the joint area of the wood panels 12 can be largely avoided.
Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Holzplatte mit einer strukturierten Oberfläche, wobei eine Decklage aus Laubholz auf eine Trägerschicht aufkaschiert und oberflächenseitig strukturgebend bearbeitet wird.The invention relates to a method for producing a wood panel with a structured surface, wherein a top layer of hardwood laminated on a support layer and the surface side is edited structuring.
Zur Profilierung der Oberfläche von Holzplatten, insbesondere für Holzböden, ist es bekannt (
Der Erfindung liegt somit die Aufgabe zugrunde, die Oberfläche einer Holzplatte durch ein Bearbeitungsverfahren so zu strukturieren, dass die Holzplatten ohne Festigkeitsverlust im Bereich einer Oberflächenschicht mit einem vergleichsweise geringen Arbeitsaufwand formgebend strukturiert werden können.The invention is thus based on the object of structuring the surface of a wood panel by a processing method so that the wood panels can be structured without sacrificing strength in the region of a surface layer with a comparatively small amount of work.
Die Erfindung löst die gestellte Aufgabe dadurch, dass die Decklage mit einem Feuchtigkeitsgehalt zwischen 7 und 9 %, vorzugsweise zwischen 7,5 und 8,5 %, auf die Trägerschicht aufkaschiert wird, bevor die Oberfläche der Decklage durch ein Prägen formgebend strukturiert wird.The invention achieves this object by laminating the cover layer with a moisture content of between 7 and 9%, preferably between 7.5 and 8.5%, onto the carrier layer before the surface of the cover layer is shaped by embossing.
Um das Laubholz der Decklage ohne einen die Festigkeit der zu strukturierenden Oberflächenschicht beeinträchtigenden Faserbruch spanlos durch ein Prägen formgebend bearbeiten zu können, ist der Feuchtigkeitsgehalt der Decklage zwischen 7 und 9 % einzustellen, sodass mit dem beim Prägen örtlich aufzubringenden Druck auf die Decklage die Holzfasern mit einem für eine bleibende Strukturierung ausreichenden Druck ohne Faserbruch plastisch verformt werden können. Eine solche formgebende Strukturierung der Oberfläche der Decklage setzt allerdings eine ausreichende Druckfestigkeit der Trägerschicht voraus, was zwar bei Trägerschichten aus Sperrholz und anderen Holzwerkstoffen mit einer entsprechenden Druckfestigkeit, nicht aber bei üblichen Trägerschichten aus Nadelholzleisten gegeben ist. Aus diesem Grunde ist beim Einsatz von Trägerschichten ein Jahresringverlauf der Nadelholzleisten quer zur Trägerschicht vorzusehen. Ein solcher Jahresringverlauf bringt eine Steigerung der Druckfestigkeit der Trägerschicht um mehr als das Doppelte mit sich. Für Fichtenholzleisten kann durch diese Maßnahme eine Brinellhärte von ca. 30 bis 35 N/mm2 erreicht werden. Für Kiefernholz liegt diese Brinellhärte bei ca. 40 N/mm2. Diese Druckfestigkeit der Trägerschicht reicht zur Abstützung der aufkaschierten Decklage aus, um diese Oberflächenschicht der Decklage mit einem auf eine Längeneinheit bezogenen Druck von 30 bis 150 N/mm, vorzugsweise von 50 bis 100 N/mm dauerhaft und schonend nutenförmig prägen zu können. Nach diesem Prägevorgang kann die Oberfläche der Decklage in an sich bekannter Weise geölt und gewachst bzw. lackiert werden.In order to edit the hardwood top layer without affecting the strength of the structuring surface layer affecting fiber fraction without cutting by embossing, the moisture content of the top layer is set between 7 and 9%, so with the locally applied during embossing pressure on the top layer of wood fibers sufficient pressure for a permanent structuring without fiber break can be plastically deformed. However, such a shaping structuring of the surface of the cover layer requires sufficient compressive strength of the carrier layer, which is true given in carrier layers of plywood and other wood materials with a corresponding compressive strength, but not in conventional carrier layers of needlewood. For this reason, when using carrier layers, an annual ring course of the needle wooden strips is to be provided transversely to the carrier layer. Such an annual ring course brings about an increase in the compressive strength of the carrier layer by more than twice. For spruce laths, a Brinell hardness of about 30 to 35 N / mm 2 can be achieved by this measure. For pine wood, this Brinell hardness is about 40 N / mm 2 . This compressive strength of the carrier layer is sufficient to support the laminated cover layer in order to be able to emboss this surface layer of the cover layer permanently and gently with a groove of 30 to 150 N / mm, preferably 50 to 100 N / mm, based on a unit length. After this stamping process, the surface of the cover layer can be oiled and waxed or painted in a conventional manner.
Da beim stumpfen Stoßen zweier Holzplatten nicht damit gerechnet werden kann, dass die in die Oberfläche der Decklage nutenartigen Vertiefungen im Stoßbereich fluchten, besteht die Gefahr, dass Feuchtigkeit in die stirnseitig nicht ausreichend behandelte Decklage eindringt. Um dies zu vermeiden, kann die Decklage an der umlaufenden Oberkante mit einer Fase versehen werden, deren Tiefe größer als die Tiefe der Oberflächenprägung ist, sodass die nutenartigen Vertiefungen im Bereich dieser Fasen auslaufen.Since the blunt collision of two wooden panels can not be expected that the grooves in the surface of the cover groove-like recesses in the joint area, there is a risk that moisture penetrates into the front side not sufficiently treated cover layer. To avoid this, the cover layer can be provided at the peripheral upper edge with a chamfer, the depth of which is greater than the depth of the surface embossing, so that the groove-like depressions leak in the region of these chamfers.
Damit die durch das Prägen gebildeten, nutenartigen Vertiefungen im Oberflächenbereich der Decklage nicht zu Reinigungsproblemen führen können, kann die Oberfläche der Decklage mit einem Flankenwinkel kleiner als 75° geprägt werden. Der vergleichsweise kleine Neigungswinkel der Flanken der nutenartigen Vertiefungen bringt außerdem eine größere Sicherheit gegenüber einem Faserbruch im Bereich der Flanken der Vertiefungen mit sich.So that the groove-like depressions formed by embossing in the surface region of the cover layer can not lead to cleaning problems, the surface of the cover layer can be embossed with a flank angle of less than 75 °. The comparatively small angle of inclination of the flanks of the groove-like depressions also brings greater security against fiber breakage in the region of the flanks of the depressions.
Zur Verbesserung der Geschmeidigkeit der Holzfasern kann die Decklage vor dem Einprägen nutenartiger Vertiefungen mit einem die Biegeweichheit der Holzfasern steigernden Mittel vorbehandelt werden. Für diesen Einsatzzweck bieten sich verschiedene Oberflächenbehandlungen, beispielsweise durch Ölen, an.To improve the suppleness of the wood fibers, the cover layer can be pretreated before embossing groove-like depressions with an increasing the bending softness of the wood fibers agent. For this purpose, various surface treatments, for example by oils, offer.
Zur Durchführung der Oberflächenbearbeitung der Decklage durch ein Prägen ist für eine lastabtragende Abstützung der Holzplatte gegenüber dem Prägedruck zu sorgen, der vorzugsweise mit Hilfe einer Prägewalze aufgebracht wird, die mit der Negativform der herzustellenden nutenartigen Vertiefungen entsprechenden, rippenartigen Prägeansätzen versehen ist. Diese einer angetriebenen Gegendruckwalze gegenüberliegende Prägewalze wird mit Hilfe eines Stelltriebes an die Gegendruckwalze angestellt und weist einen Durchmesser auf, der höchstens einem Drittel des Durchmessers der Gegendruckwalze entspricht. Aufgrund dieses Durchmesserverhältnisses kann der beim Prägen der Oberflächenschicht der Decklage auftretende Liniendruck auf eine ausreichende Fläche der Trägerschicht abgetragen werden, um die Trägerschicht hinsichtlich ihrer Druckfestigkeit nicht zu überlasten.For performing the surface treatment of the cover layer by embossing is to provide a load-bearing support of the wood panel against the embossing, which is preferably applied by means of an embossing roll, which is provided with the negative shape of the groove-like depressions corresponding rib-like embossing approaches. This embossing roller opposite a driven counter-pressure roller is set with the aid of an actuating drive to the counter-pressure roller and has a diameter which corresponds to at most one third of the diameter of the counter-pressure roller. Because of this diameter ratio, the line pressure occurring when embossing the surface layer of the cover layer can be removed to a sufficient surface area of the carrier layer so as not to overload the carrier layer with respect to its compressive strength.
Damit einerseits der erforderliche Prägedruck feinfühlig eingestellt und anderseits die Prägewalze gegenüber der zu strukturierenden Decklage der Holzplatte quer zur Förderrichtung ausgerichtet werden kann, empfiehlt es sich, die Prägewalze in einem achsparallel verfahrbaren Schlitten zu lagern, an dessen verschiebbar gelagerter Führung der Stelltrieb zur Anstellung der Prägewalze an die Gegendruckwalze angreift. Die axiale Schlittenführung ermöglicht die jeweils geforderte Ausrichtung der Prägewalze quer zur Förderrichtung der Gegendruckwalze, während die Prägekraft über die Schlittenführung aufgebracht wird.Thus, on the one hand the required embossing pressure sensitively adjusted and on the other hand, the embossing roller can be aligned with respect to the structured top layer of the wood panel transversely to the conveying direction, it is recommended that the embossing roller to store in an axially movable carriage on the displaceably mounted guide the actuator for employment of the embossing roller engages the counter-pressure roller. The axial slide guide allows the respectively required alignment of the embossing roll transversely to the conveying direction the counter-pressure roller while the embossing force is applied via the carriage guide.

Bevor die Decklage 15 auf die Trägerschicht 13 aufgebracht wird, muss die Decklage hinsichtlich ihrer Feuchtigkeit eingestellt werden, wobei sich eine Forderung nach einer Mindestfeuchtigkeit von 7 % und einer größten Holzfeuchte von 9 % als Voraussetzung für ein weitgehend bruchfreies Prägen der Holzfasern ergibt. Die beidseitig geschliffenen Holzplatten 12 werden dann zwischen der Prägewalze 10 und der Gegendruckwalze 3 entsprechend den Prägeansätzen der Prägewalze 10 formgebend bearbeitet, indem die Prägeansätze mit einem an die jeweiligen Verhältnisse angepassten Prägedruck in die Oberflächenschicht der Decklage 15 eingedrückt werden, und zwar bei einer ausreichenden plastischen Verformung der Holzfasern, um eine bleibende Prägung in Form von nutenartigen Vertiefungen 17 zu erhalten. Die Prägeansätze der Prägewalze 10 sind im Querschnitt so geformt, dass sich eine Neigung der Flanken dieser Prägeansätze von höchstens 75° ergibt. Solche Flankenwinkel helfen nicht nur, die Decklage 15 einfach oberflächlich zu reinigen, sondern unterstützen auch die schonende Verformung der Holzfasern im Bereich der nutenartigen Vertiefungen 17.Before the
Trotz des notwendigen Prägedruckes bis zu 150 N/mm können diese linienförmig aufgebrachten Drücke ohne Überlastung der Trägerschicht 13 auf die Gegendruckwalze 3 abgetragen werden, weil einerseits der Jahresringverlauf der Nadelholzleisten 14 entsprechend gewählt wurde und ein Durchmesserverhältnis zwischen der Gegendruckwalze 3 und der Prägewalze 10 von wenigstens 3 eingehalten wird, was eine entsprechende Druckverteilung über einen größeren Oberflächenbereich der Holzplatte 12 auf der Seite der Gegendruckwalze 3 erlaubt.Despite the necessary embossing pressure up to 150 N / mm, these line-applied pressures can be removed without overloading the
Beim Fügen zweier geprägter Holzplatten 12 ist damit zu rechnen, dass die nutenartigen Vertiefungen 17 im Stoßbereich zwischen den Holzplatten 12 nicht fluchten und daher an der Stirnseite der Decklage 15 der anschließenden Holzplatte 12 enden. Damit die Stirnseite der Decklage 15 im Bereich der endenden nutenartigen Vertiefungen 17 nicht durch eindringende Feuchtigkeit belastet werden kann, kann die umlaufende Oberkante der Decklage 15 mit einer Fase 18 versehen werden, wie sie in der
