Bandschleifmaschinen für Holz o. dgl. bestehen gewöhnlich aus zwei Rollen, die ein endloses Schleifband tragen. Das riemenartig laufende Schleifband wird mittels eines Druckschuhes an das zu schleifeinde Holz angedrückt. Bisher verwendet man feststehende, mit Filz oder Leder überzogene Druckschuhe oder solche aus Holz. Solche Druckschuhe haben den Nachteil, daß sie das Schleifband nichtBelt sanders for wood o. The like. Usually consist of two rollers that one wearing endless sanding belt. The belt-like running sanding belt is made by means of a pressure shoe pressed against the wood to be sanded. So far one used fixed, with Felt or leather covered pressure shoes or those made of wood. Have such pressure shoes the disadvantage that they do not use the sanding belt to genau eben an das zu schleifende Holz drükken können, denn diese Druckschuhe werden einseitig abgenutzt. Das ebene Schleifen von Flächen wird dadurch erheblich erschwert, besonders wenn furnierte Flächen geschliffen werden sollen. Es besteht hier die Gefahr des Durchschleifens der Furniere.to be able to press exactly against the wood to be sanded, because these pressure shoes are worn on one side. The level sanding of surfaces is made considerably more difficult as a result, especially when veneered surfaces are to be sanded. There is danger here sanding through the veneers. Dieser Nachteil wird an der erfindungsgemäßen Bandschleifmaschine dadurch beseitigt, daß das Schleifband mittels eines teller- This disadvantage is eliminated in the belt grinding machine according to the invention in that the grinding belt is ao förmigen Druckschuhes angedrückt wird, dessen umlaufende Ebene senkrecht zu der des umlaufenden Schleifbandes liegt. Dadurch wird das Schleifband gleichmäßig angedrückt, und der Druckschuh kann infolge der umlaufenden Bewegung nicht einseitig abgenutzt werden, sondern bleibt immer gleichmäßig eben.ao-shaped pressure shoe is pressed, the circumferential plane of which is perpendicular to that of the circumferential sanding belt. As a result, the sanding belt is pressed evenly, and the pressure shoe cannot be worn on one side as a result of the revolving movement but always remains evenly flat. Dadurch werden schnell und mühelos schöne ebene Flächen erzielt, und das Schleifband gleitet leichter unter den umlaufenden Druckschuh hinweg. Hinter dem tellerförmigen Druckschuh kairm in bekannter Weise leine Staubsaugvorrichtung angebracht werden, die den restlichen Staub absaugt.This means that beautiful, flat surfaces are achieved quickly and effortlessly, as is the sanding belt slides more easily under the circumferential pressure shoe. Behind the plate-shaped Pressure shoe kairm in a known way be attached leash vacuum cleaner, which sucks off the remaining dust. In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Bandschleifmaschine dargestellt, und zwar in Abb. 1 in einem lotrechten Schnitt und in Abb. 2 in Ansicht von oben.In the drawing is an embodiment of the belt grinder according to the invention shown, namely in Fig. 1 in a vertical section and in Fig. 2 in View from above. Unter dem Schleifband 1 liegt das zu schleifende Brett 2, der tellerförmige Druckschuh 3 mit der Filzauflage 4 sitzt über dem Schleifband i. Das Schleifband bewegt sich in der Pfeilrichtung, der Druckschuh 3 wird so in Umlauf gesetzt, daß dessen umlaufende Ebene senkrecht zu der des umlaufenden Schleifbandes liegt und in bekannter Weise an das Schleifband 1 gedrückt. Außerdem kann der umlaufende, tellerförmige Druckschuh in gewöhnlicher Weise seitlich verschoben werden.The one to be sanded lies under the sanding belt 1 Board 2, the plate-shaped pressure shoe 3 with the felt pad 4 sits above the sanding belt i. The sanding belt moves in the direction of the arrow, the pressure shoe 3 is so in Circulation set that its circumferential plane is perpendicular to that of the rotating abrasive belt and pressed against the grinding belt 1 in a known manner. In addition, the circumferential, plate-shaped pressure shoe can be moved laterally in the usual way.
