Description
Profilierte Sperrholzplatte Die vorliegende Erfindung bezieht sich auf eine profilierte Sperrholzplatte, zum Bei spiel ein dekoratives Paneel-, eine Tür- und Wandbekleidung oder ein anderes Bauele ment, aber a.ucli ein. Möbelteil wie Stuhlsitz, Stuhllehne, sowie für dekorative Verpaekun- gen.
Bekannt. ist, profiliertes Sperrholz dadurch herzustellen, dass Holzleisten- oder =lamellen in beliebigen Zwischenräumen nebeneinander auf der einen ,Seitenfläche fertiger Sperr holzplatten aufgeleimt werden. Dabei wur den stets die Faserrichtungen benaehbarter Sehfichten. senkreeht zueinander gewählt. Die ses bekannte Verfahren hat. den Nachteil, dass sieh die aufgeleimten Lamellen häufig vom Sperrholz lösen.
Wenn ferner die Fasern der verschiedenen Schichten in parallelen Rich tungen verlaufen, besteht die Gefahr eines Suchwerfens der ganzen Platte unter dem Binfluss der Temperatur oder der Feuehtig- keit, die verschiedene Wirkungen auf die ver schiedenen Schichten haben können.
Diese Nachteile werden durch die erfin dungsgemässe profilierte Sperrholzplatte ver mieden, die dadurch gekennzeichnet ist, dass sie aus mehreren Ho@l!zschichten besteht., wobei gerade Rillen eine äusserste Schicht ganz. und die der letzteren benachbarte 'Schicht teil weise durchsetzen, welche Schichten parallel verlaufende Fasern aufweisen.
Es hat. sich gezeigt., dass es möglich ist., auf diese Weise profiliertes Sperrho'l'z 'herzustellen, das eine grosse Widerstandsfähigkeit gegen ein 'Such- werfen des Holzes aufweist. Falls die äusserste Schicht. und die angrenzende Schicht der Sperrholzplatte aus verschiedenen Holzsorten bestehen, bzw. verschiedene Einfärbungen aufweisen, ergibt. sieh eine besonders dekora tive Wirkung.
In der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegen- standes dargestellt. Es zeigen: Fig.1 einen 'Teil einer profilierten Sperr- holzp'latte im Grundruss, Fig.2. einen Querschnitt nach der Linie II-II in F'ig. 1, Fig. 3 eine perspektivische- Teilansicht einer andern Sperrholzplatte.
In Fig.1 und \' bezeichnet 1 die eine der Aussenschichten einer aus fünf auf bekannte Weise zusammengeleinten ebenen .Schichten 1, 0', 5, 7 und 9 bestehenden Sperrholzplatte. In der Schicht. 1 sind gleichlaufende gerade Rillen 2- aasgekehlt., die von den die Aussen schichtbildenden Leisten oder Lamellen 4 be grenzt sind; diese Rillen greifen ebenfalls in die nächste der Schicht 1 benachbarte Schicht 3.
Diese Rillen '2a haben einen recht winkligen Querschnitt.
Die Rillen 2 können jedoch eine beliebig andere Querschnittsform aufweisen. Zweck mässig werden die Rillen parallel zur Faser richtung der Schicht 1 eingeschnitten.
Das Schneiden der Rillen in die fünf schichtige Platte erfolgt in einer Hobel- oder Fräsmaschine mit einem profilierten Messer entsprechend der für die Oberfläche der Aussenschicht gewünschten Form. Alle gleich laufenden Rillen in ein und derselben. Sperr- holzplatte werden in einem einzigen Arbeits gang gekehlt.
Es sei bemerkt, dass die in Fig. \?. ge zeigten Schraffierungen der Schichten 1, 3, 5, 7 und 9 nicht die Faserrichtungen in den verschiedenen Schichten angehen, sondern nur bedeuten, dass Fig. ?. einen Querschnitt durch das Sperrholz darstellt..
Bei der beschriebenen, profilierten Sperr holzplatte, bei welcher die Rillen \? die ganze Aussenschicht 1 durchschneiden und sich noch in die angrenzende Schicht 3 hineinstreeken, sind - wie bereits erwähnt - -um die Gefahr eines Sichwerfens des Sperrholzes auf ein Mindestmass zu beschränken, die Faserrich tungen des Holzes der Schichten,1 und 3 zueinander parallel, und aus denselben Grün den ist es ebenfalls vorteilhaft,
die Faser richtungen des Holzes der Schichten 7 und 9 auf der andern Seite der Sperrholzplatte par allel zur Faserrichtung der beiden. ,Schichten 1 und 3 anzuordnen. Die Faserrichtung der INlittelsehieht 5 verläuft quer zur F'aserrieh- tung der vier andern Schichten 1, 3, 7 und 9.
Man könnte aber auch die Fasern der Schichten 1, 3 in eine Richtung und die der Schichten 5, 7, 9 in die andere verlaufen lassen. Die Rillen \_'i sind paarweise angeordnet in Fig. 1, ?, wobei der Abstand a. der Rillen jedes Paares kleiner als der Abstand b zweier Paare ist. Wie ans Fig. 3 hervorgeht, könnten diese Abstände auch gleich gewählt werden.
Es hat sich in der Praxis gezeigt, dass die beschriebenen Sperrholzplatten eine über raschende Widerstandsfä.higheit gegen ein Sich-werfen aufweisen. Die zweite Schicht rea gierte unter dem Einfluss einer Temperatur- oder Feuchtigkeitsvariation wie die erste.
Dieser Effekt ist der Wirkung der durch gehenden Rillen zuzuschreiben. Die beschrie bene Sperrliolzpla.tte kann somit in Ländern mit einem feneliten. Klima füglich als Bauele ment. verwendet werden und entgegen der bisher in der Fachwelt vertretenen Ansichten.
Profiled plywood sheet The present invention relates to a profiled plywood sheet, for example a decorative panel, door and wall cladding or another component, but a.ucli. Furniture part such as chair seat, chair back and for decorative packaging.
Known. is to produce profiled plywood by gluing wooden strips or lamellas next to each other in any space on one side of finished plywood panels. The fiber directions of adjacent visual spruces were always used. chosen perpendicular to each other. This has known procedure. the disadvantage that the glued-on lamellas often detach from the plywood.
Furthermore, if the fibers of the various layers run in parallel directions, there is a risk of the whole plate being thrown under the influence of temperature or fire resistance, which can have different effects on the various layers.
These disadvantages are avoided by the profiled plywood sheet according to the invention, which is characterized in that it consists of several layers of wood, with straight grooves completely forming an outermost layer. and partially enforce the layer adjacent to the latter, which layers have parallel fibers.
It has. It has been shown that it is possible to produce profiled plywood in this way, which is highly resistant to being thrown in search of the wood. If the outermost layer. and the adjacent layer of the plywood panel consist of different types of wood, or have different colors, results. see a particularly decorative effect.
An exemplary embodiment of the subject of the invention is shown in the accompanying drawing. They show: FIG. 1 a part of a profiled plywood plate in the base, FIG. 2. a cross-section along the line II-II in F'ig. 1, 3 is a partial perspective view of another sheet of plywood.
In FIGS. 1 and 1, 1 denotes one of the outer layers of a sheet of plywood consisting of five planar layers 1, 0 ', 5, 7 and 9 that are tied together in a known manner. In the shift. 1 are concurrent straight grooves 2- aasgekehlt. Which are bordered by the outer layer-forming strips or slats 4 be; these grooves also engage in the next layer 3 adjacent to layer 1.
These grooves' 2a have a right angled cross-section.
However, the grooves 2 can have any other cross-sectional shape. Appropriately, the grooves are cut parallel to the fiber direction of the layer 1.
The grooves are cut in the five-layer board in a planing or milling machine with a profiled knife according to the shape desired for the surface of the outer layer. All grooves running in the same direction in one and the same. Plywood panels are grooved in a single operation.
It should be noted that the in Fig. \ ?. Ge showed hatching of layers 1, 3, 5, 7 and 9 do not concern the fiber directions in the different layers, but only mean that Fig. represents a cross-section through the plywood ..
In the case of the profiled plywood board described, in which the grooves \? Cut through the entire outer layer 1 and still stretch into the adjacent layer 3 - as already mentioned - in order to limit the risk of the plywood throwing itself to a minimum, the fiber directions of the wood of the layers, 1 and 3 parallel to each other, and for the same reasons it is also advantageous
the fiber directions of the wood of layers 7 and 9 on the other side of the plywood sheet par allel to the fiber direction of the two. To arrange layers 1 and 3. The fiber direction of the middle layer 5 runs transversely to the fiber direction of the four other layers 1, 3, 7 and 9.
But you could also let the fibers of the layers 1, 3 run in one direction and those of the layers 5, 7, 9 in the other. The grooves \ _'i are arranged in pairs in Fig. 1,?, The distance a. of the grooves of each pair is smaller than the distance b between two pairs. As can be seen from FIG. 3, these distances could also be chosen to be the same.
It has been shown in practice that the plywood panels described have a surprising ability to resist throwing themselves. The second layer responded like the first under the influence of a temperature or humidity variation.
This effect is due to the effect of the continuous grooves. The above-mentioned Sperrliolzpla.tte can therefore be used in countries with a fenelite. Climate suitable as a component. are used and contrary to the views previously represented in the professional world.
