Description

  

      Sperrholzplatte.       Die Erfindung betrifft eine Sperrholz  platte. Bekannte     Sperrholzplatten    bestehen  aus     Langholzleisten,    die beiderseits mit Fur  nieren     beleimt    werden, wobei man je nach der  Anzahl der Furniere und der Mittellage von  einer 3fachen, 5fachen, 7fachen usw. Sperr  holzplatte spricht.  



  Erfindungsgemäss werden die bekannten       Sperrholzplatten    dadurch verbessert, dass ihre  beiderseits mit Furnieren     beleimte    Mittellage  aus in Abstand voneinander regellos angeord  neten     Hirnholzklötzchen    von gleicher Höhe  besteht, deren Stirnflächen den Furnieren zu  gewandt sind. Auch hier können auf jede       ,3eite    eine, zwei, drei oder mehr Furniere auf  geleimt sein.  



  Man erhält auf diese Weise eine Sperr  holzplatte, die völlig verzugsfest ist. Ein wei  terer Vorteil besteht darin, dass beträchtliche       Nutzholzmengen    eingespart werden, was zu  einer Verbilligung in der Herstellung führt.  Schliesslich ist der     Verschnittv    erlast gering,  und ein besonderer Vorteil des Erfindungs  gegenstandes besteht darin, dass keinerlei be  sondere Bedingungen an den Querschnitt des  Hirnholzes gestellt zu werden brauchen. Jede  Dimension des anfallenden Stammes kann  daher benutzt. werden; auch irgendwelches    Stangen- oder Abfallholz ist als Hirnholz zu  benutzen. Hierdurch wird weiter die Herstel  lung des Erfindungsgegenstandes verbilligt.  



  Die beiliegende Abbildung zeigt in verein  fachter Darstellung ein Ausführungsbeispiel  der Erfindung. Es zeigen:       Fig.    1. eine Ansicht,       Fig.    2 einen Schnitt nach Linie     II-II     der     Fig.    3,       Fig.    3 einen Querschnitt.  



  Bei der     Sperrholzplatte    nach den     Fig.1     bis 3 besteht, die Mittellage aus einer grö  sseren Anzahl von in nicht zu grossem Ab  stand voneinander regellos angeordneten  Hirnholzklötzen 1 gleicher Höhe, deren Quer  schnitt verschieden ist. Auf den beiden Stirn  seiten dieser Hirnholzklötze 1 sind je ein  Furnier 2 und 3 geleimt. Stattdessen können  auch auf jeder Seite mehrere Furniere mit  den Fasern kreuzweise     übereinandergeleimt     sein.



      Plywood board. The invention relates to a plywood plate. Known plywood panels consist of long wooden strips, which are glued on both sides with fur kidneys, depending on the number of veneers and the middle layer of a 3-fold, 5-fold, 7-fold, etc. plywood speaks.



  According to the invention, the known plywood panels are improved in that their middle layer, glued on both sides with veneers, consists of end-grain blocks of the same height, which are randomly arranged at a distance from one another and whose end faces face the veneers. Here, too, one, two, three or more veneers can be glued onto each side.



  In this way, a plywood board is obtained that is completely resistant to distortion. Another advantage is that considerable amounts of timber are saved, which leads to cheaper production. Finally, the waste load is low, and a particular advantage of the subject matter of the invention is that no special conditions need to be imposed on the cross-section of the end grain. Every dimension of the resulting trunk can therefore be used. will; Any logs or waste wood can also be used as end grain. This further reduces the cost of the manufacture of the subject matter of the invention.



  The accompanying figure shows a simplified representation of an embodiment of the invention. There are shown: FIG. 1 a view, FIG. 2 a section along line II-II in FIG. 3, FIG. 3 a cross section.



  In the plywood sheet according to FIGS. 1 to 3, the middle layer consists of a larger number of end-grain blocks 1 of the same height, whose cross-section is different, which were randomly arranged from one another in not too great a distance. A veneer 2 and 3 are glued on each of the two end faces of these end grain blocks 1. Instead, several veneers with the fibers can be glued crosswise on each side.
