 EMI1.1 
 



   Die vorliegende Erfindung behandelt eine Vorrichtung zur Herstellung von gewelltem Holzspan, bei welcher die Wellung des Spanes durch entsprechend profilierte Walzen erfolgt. Beim Eindrücken des Spanes in die Riefelung der   eipen   Walze greift das. harte Material der anderen Walze den Span unmittelbar an und reibt während des Eindrückens des Holzes in die Riefelung auf dem Span, so dass der Span infolge seiner Sprödigkeit schon bei der Formgebung abgesplittert und rissig werden kann. Dieser Übelstand wird gemäss vorliegender Erfindung dadurch vermieden, dass man ein Tuch gleichzeitig mit dem zu wellenden Span zwischen den Profilwalze hindurchlaufen lässt, so dass das Tuch gleichzeitig mit dem Span deformiert wird.

   Die neue Wirkung, die hiedurch erreicht wird, besteht darin, dass der Span bei der Formgebung geschont wird, da das harte Material der oberen Profilwalze den Span beim Eindrücken in die Riefelung der anderen Walze nicht angreift, sondern der Druck von dem elastischen Material des Tuches auf den Span übertragen wird. Auf diese Weise wird ein Abstreifen von Holzfasern und ein Reissen der Fasern vermieden. 



   Die Zeichnung veranschaulicht den Erfindungsgegenstand. 



   Die eine als Heizwalze ausgebildete Profilwalze a ist mit den Rillen   b   versehen, in welche die Zähne der Profilwalze k eingreifen, so dass dem zwischen die Walzen a und k eingeführten Holzspan Wellenform erteilt wird.

 EMI1.1
 



   The present invention deals with a device for the production of corrugated wood chips, in which the corrugation of the chip is carried out by appropriately profiled rollers. When the chip is pressed into the grooves of the other roller, the hard material of the other roller attacks the chip immediately and rubs it on the chip while the wood is pressed into the grooves, so that the chip splintered and cracked as it was shaped due to its brittleness can be. According to the present invention, this inconvenience is avoided in that a cloth is allowed to run between the profile roller at the same time as the chip to be corrugated, so that the cloth is deformed simultaneously with the chip.

   The new effect that is achieved here is that the chip is spared during the shaping, since the hard material of the upper profile roller does not attack the chip when it is pressed into the fluting of the other roller, but the pressure from the elastic material of the cloth is transferred to the chip. In this way, stripping of wood fibers and tearing of the fibers is avoided.



   The drawing illustrates the subject matter of the invention.



   The one formed as a heating roller profile roller a is provided with the grooves b, in which the teeth of the profile roller k engage, so that the wood chip introduced between the rollers a and k is given a wave shape. The cloth o, which also serves to press the corrugated chip into the grooves of the roller a even after the shaping

Shaping does not attack directly, but the pressure on the chip is transferred through the cloth 0.
