Description

Die Erfindung betrifft eine Sperrholzpiatte. Die bekannten Sperrholzplatten bestehen aus Langholzleisten, die beiderseits mit Furnieren beleimt werden, wobei man je nach der Anzahl der Furniere und der Mittellage von einer 3fachen, 5fachen, 7fachen usw. Sperrholzplatte spricht.The invention relates to a sheet of plywood. The well-known plywood panels consist of long wooden strips that are glued with veneers on both sides, whereby depending on the number of veneers and the middle layer of a 3-fold, 5-fold, 7fold etc. plywood sheet speaks.

Erfindungsgemäß werden die bekannten Sperrholzplatten dadurch verbessert, daß ihre beiderseits mit Furnieren beleimte Mittellage aus in beliebigem Abstand voneinander regellos angeordneten Hirnholzklötzchen von beliebiger Form besteht, deren Stirnflächen den Furnieren zugewandt sind. Auch hier können auf jede Seite eine Furnierschicht, zwei, drei oder mehr Furnierschichten aufgelegt werden.According to the invention, the known plywood panels are improved by that their middle layer glued on both sides with veneers at any distance consists of randomly arranged end-grain blocks of any shape, whose end faces face the veneers. Again, you can go to each side a layer of veneer, two, three or more layers of veneer are placed on top.

Man erhält auf diese Weise eine Sperrholzplatte, die völlig verzugsfest ist. Ein weiterer Vorteil besteht darin, daß beträchtliche Nutzholzmengen eingespart werden, was schon an sich zu einer Verbilligung in der Herstellung führt. Schließlich ist der Verschnittverlust gering, und ein besonderer Vorteil des Erfindungsgegenstandes besteht darin, daß keinerlei besondere Bedingungen an die Form des Hirnholzes gestellt zu werden brauchen. Jede Dimension des anfallenden Stammes kann daher benutzt werden; auch irgendwelches Stangen- oder Abfallholz ist, als Hirnholz für die Ausführung der Erfindung zu benutzen. Hierdurch wird weiter die Herstellung des Erfindungsgegenstandes verbilligt.In this way, a sheet of plywood is obtained that is completely resistant to warping is. Another advantage is that it saves considerable amounts of timber become, which in itself leads to a cheaper production. In the end the waste loss is low, and a particular advantage of the subject matter of the invention consists in the fact that no special conditions are placed on the shape of the end grain need to become. Any dimension of the resulting trunk can therefore be used; Any logs or waste wood is also used as end grain for the execution to use the invention. This further increases the production of the subject matter of the invention cheaper.

Die Abbildung zeigt in vereinfachter Darstellung eine Ausführungsform der Erfindung. Es zeigt Fig. i eine Ansicht auf eine erfindungsgemäß ausgebildete Sperrholzplatte, Fig. 2 einen Planschnitt durch diese Platte nach Linie 11-1I der Fig. 3, Fig. 3 einen Querschnitt durch diese Platte nach den Fig. i und 2.The figure shows a simplified representation of an embodiment the invention. FIG. 1 shows a view of one designed according to the invention Plywood panel, Fig. 2 is a plan section through this panel along line 11-1I of the 3 and 3 show a cross section through this plate according to FIGS. 1 and 2.

Die Sperrholzplatte nach den Fig. i bis 3 besteht aus einer größeren Anzahl von in beliebigem, jedoch nicht zu weitem Abstand voneinander regellos angeordneten Hirnholzklötzen i, deren Form ebenfalls beliebig ist. Auf den beiden Stirnseiten dieser Hirnholzklötze i sind im Ausführungsbeispiel je eine Furnierplatte 2 und 3 geleimt. Statt dessen können auch auf jeder Seite mehrere Furnierplatten übereinander geleimt werden.The plywood sheet according to FIGS. I to 3 consists of a larger one Number of randomly arranged at any, but not too great a distance from one another End grain blocks i, the shape of which is also arbitrary. On the two front sides these end grain blocks i are each a veneer panel 2 and in the embodiment 3 glued. Instead, several veneer panels can be stacked on each side be glued.
