Bei den bekannten Holzschleifern mit Preßkasten ist eine ununterbrochen gleichmäßige Belastung der Schleiffläche bisher noch nicht erreicht, weil beim Füllen der Preßkästen die Schleifarbeit des jeweilig zu füllenden Preßkastens unterbrochen werden muß. Diese Unterbrechung der Schleifarbeit übt verschiedene ungünstige Wirkungen aus, wie einseitige Belastung der Schleifsteinwelle und StößeIn the case of the known wood grinders with a press box, an uninterrupted uniform The load on the grinding surface has not yet been reached because the press boxes are filled Grinding work of the respective press box to be filled must be interrupted. These Interruption of the grinding work has various unfavorable effects such as one-sided Load on the grinding stone shaft and shocks
ίο auf die Antriebsmotoren, und ergibt schließ-. lieh noch einen ungleichmäßigen Stoff.ίο on the drive motors, and results in closing. still borrowed an uneven fabric.
Zur Beseitigung dieser Übelstände ist angeregt worden, durch die eigene Last des Schleifholzes den erforderlichen gleichmäßigen Druck zu erzeugen. Abgesehen, daß man dabei zu Ausführungen kommt, welche eine Holzsäule von 20 und mehr Meter Höhe voraussetzt, führt diese Ausführung auch nicht zu einem befriedigenden Ergebnis, weil dabei eine Regelung des Druckes bei schwankender Kraft nicht durchführbar sein würde.To remedy these evils has been suggested by the own burden of the Sanding wood to generate the required even pressure. Apart from that one this comes to statements that require a wooden column of 20 and more meters in height, this design also does not lead to a satisfactory result, because it regulates the pressure when the pressure fluctuates Force would not be feasible.
Auch die Zuführung des Schleifholzes durch Riffelwalzen, welche den Vorschub des Schleifholzes bewirken, ist praktisch schwer durchführbar, da eine derartige Einrichtung zu hohe Anforderungen an die Beschaffenheit des Schleifholzes stellen würde, welche in Wirklichkeit nicht zu erfüllen sind.Also the feeding of the sanding wood by corrugating rollers, which feed the sanding wood effect is practically difficult to carry out because such a device is too would make high demands on the quality of the sanding wood, which in reality are not to be fulfilled.
Um die eingangs genannten Nachteile zu beseitigen und eine stets gleich groß bleibende Schleiffläche zu erhalten, ist die den Gegenstand der Erfindung bildende Ausführung getroffen worden.In order to eliminate the disadvantages mentioned at the beginning and always remain the same To obtain grinding surface, the embodiment forming the subject of the invention is met been.
Über dem Schleifstein s sind ein oder mehrere Preßkasten α angebracht, welche einen größeren Holzvorrat aufnehmen können. Um ein Klemmen des Holzes zu verhüten, ver-Above the grindstone s one or more press boxes α are attached, which can accommodate a larger supply of wood. To prevent the wood from jamming,
