Description

  

      Tischlerplatte.       Die     bekannten        Tischlerplatten    bestehen  oft aus einer     Blindholzlage,    die ein- oder  beidseitig mit     Furnierblättern    versehen ist.  Wichtig     ist    hierbei die Beschaffenheit der       Blindholzlage,    da     diese    für die Festigkeit  der Platte     bestimmend    ist.

   Während die       Blindholzlage    bekannter Tischlerplatten aus  miteinander verleimten     Holzstäbchen    besteht,       wobei    das Planbleiben der Platte von der  Breite der zusammengeleimten Stäbchen ab  hängt, besteht bei der     Tischlerplatte    nach der  vorliegenden Erfindung die     Blindholzlage     aus einem zusammenhängenden Holzbrett,  das mindestens     einseitig        mit    in Faserrichtung  des Holzes verlaufenden Schlitzen versehen       ist.    Dadurch kommt das lästige und zeit  raubende     Verleimen    von     Holzstäbchen    in  Wegfall,

   während man trotzdem eine span  nungsfreie und gut     abgesperrte    Tischler  platte erhalten kann.  



  Auf der beiliegenden Zeichnung ist ein  Ausführungsbeispiel des Erfindungsgegen  standes veranschaulicht.         Fig.    1 zeigt im     Schaubild    eine Blindholz  lage.  



       Fig.    2 zeigt einen Längsschnitt durch eine  fertige     Tischlerplatte,    und       Fig.    8 zeigt     eine    Stirnansicht einer sol  chen Platte.    Die in     F'ig.    1     dargestellte        Blindholzlage     1 besteht aus einem     ununterbrochen    durch  gehenden Holzbrett, wie solches aus Baum  stämmen gesägt     wird.    In diesem Brett sind  mehrere parallel zueinander, in Richtung der  Fasern verlaufende Schlitzreihen angeordnet.

    Eine solche Schlitzreihe     weist        eine    Anzahl       hintereinander    liegende Schlitze 2 auf, die  durch die ganze Brettstärke durchgehen, und  die zu den Schlitzen der benachbarten Schlitz  reihen versetzt sind. Diese in verhältnis  mässig geringen Abständen (ca. 8 mm) von  einander angeordneten Schlitzreihen haben  den Zweck, die     Jahresringe    des Holzes zu  unterbrechen, wodurch die naturgemäss in  einem     Holzbrett    vorhandenen     Spannungen         sich ausgleichen können und ein Reissen des  Brettes vermieden wird.  



  Zweckmässig werden, wie in     Fig.    2 ge  zeigt ist, die Schlitze, die nebeneinander zu  liegen kommen, abwechslungsweise von bei  den Seiten her in das Holzbrett eingesägt.  



  Die     Blindholzlage    1 wird, um eine ge  brauchsfertige Tischlerplatte zu erhalten,  beidseitig mit     Furnierblättern    3 verleimt, wie  aus     Fig.    2 und 3 ersichtlich ist.  



  Es ist nicht notwendig, dass die Schlitze  der     Blindholzlage    das Brett in der ganzen    Dicke     durchsetzen;    sie     könnten    dasselbe auch  nur teilweise durchsetzen.



      Blockboard. The known blockboard often consist of a blind wood layer, which is provided on one or both sides with veneer sheets. The quality of the blind wood layer is important here, as this is decisive for the strength of the panel.

   While the blind wood layer of known blockboard consists of wooden sticks glued together, whereby the flatness of the plate depends on the width of the glued together sticks, in the blockboard according to the present invention the blind wood layer consists of a coherent wooden board, which has at least one side with slots running in the direction of the grain of the wood is provided. This eliminates the annoying and time-consuming gluing of wooden sticks,

   while you can still get a tension-free and well-sealed joiner's board.



  On the accompanying drawing, an embodiment of the subject invention is illustrated. Fig. 1 shows a blind wood location in the diagram.



       Fig. 2 shows a longitudinal section through a finished blockboard, and Fig. 8 shows an end view of such a plate. The one in Fig. 1 shown blind wood layer 1 consists of an uninterrupted continuous wooden board, as such is sawn from tree trunks. In this board several parallel rows of slots are arranged in the direction of the fibers.

    Such a row of slots has a number of slots 2 lying one behind the other, which pass through the entire board thickness, and which are offset from the slots of the adjacent slot rows. These rows of slots, which are arranged at relatively small intervals (approx. 8 mm) from each other, have the purpose of interrupting the annual rings of the wood, so that the tensions naturally present in a wooden board can be balanced out and the board is prevented from tearing.



  Appropriately, as shown in Fig. 2, the slots that come to lie next to each other, alternately sawn from the sides in the wooden board.



  The blind wood layer 1 is, in order to obtain a ready-to-use blockboard, glued on both sides with veneer sheets 3, as can be seen from FIGS. 2 and 3.



  It is not necessary for the slots in the blind wood layer to penetrate the entire thickness of the board; they could only partially enforce it.
