KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. 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 Rieflung der einen Walze greift das harte Material der anderen Walze den Span unmittelbar an und reibt während des Eindrückens des Holzes in die Rief lung auf dem Span entlang, soThe present invention relates to an apparatus for making corrugated Wood chips, in which the corrugation of the chip is made by appropriately profiled rollers. When the chip is pressed into the grooves of one of the rollers, the hard material grips the other roller directly on the chip and rubs while the wood is pressed in along the grooves on the chip, like this ίο daß infolge der Sprödigkeit des Materials schon bei der Formgebung der Span abgesplittert und rissig werden kann. Dieser Übelstand soll gemäß vorliegender Erfindung dadurch vermieden werden, daß man ein Tuch gleichzeitig mit dem zu wellenden Span zwischen den Profilwalzen hindurchlaufen läßt. Die neue Wirkung, die hierdurch erreicht werden soll, besteht darin, daß bei der Formgebung der Span insofern geschont wird, als beim Eindrücken des Holzes in die Rieflung der Walze α nicht das harte Material der oberen Profilwalze den Span angreift, sondern der Druck bei der Formgebung von dem elastischen Material des Tuches auf den Span übertragen wird. Auf diese Weise soll ein Abstreifen von Holzfasern , sowie ein Reißen der Fasern bei der Formgebung vermieden werden.ίο that due to the brittleness of the material, the chip can split off and crack during the shaping process. According to the present invention, this disadvantage is to be avoided in that a cloth is allowed to run between the profile rollers at the same time as the chip to be corrugated. The new effect that is to be achieved in this way is that during the shaping of the chip is spared insofar as when the wood is pressed into the grooves of the roller α, not the hard material of the upper profile roller attacks the chip, but the pressure in the Shaping is transferred from the elastic material of the cloth to the chip. In this way, stripping of wood fibers and tearing of the fibers during shaping should be avoided. Die Zeichnung veranschaulicht den Erfindungsgegenstand. The drawing illustrates the subject matter of the invention. Die eine als Heizwalze ausgebildete Profilwalze α 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. Das Tuch ο, welches gleichzeitig dazu dient, den gewellten Span auch nach der Formgebung in die Rillen der Walze a eingepreßt zu halten, ist über die Profilwalze k, über etwa 3/4 des Umfanges der Walze α und über die Führungswalzen η geführt und läuft gleichzeitig mit dem zu pressenden Span zwischen den Walzen a und k hindurch.The one formed as a heating roller profile roller α 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 ο, serving which at the same time to keep the corrugated chip pressed even after the shaping into the grooves of the roller a, k over the profile roller, α over about 3/4 of the circumference of the roll and guided η over the guide rollers and runs at the same time as the chip to be pressed through between the rollers a and k.
