Description

Vorrichtung zur Verhinderung des Abreißens des Belages umlaufender Schleif-bzw. Polierbänder Schleif- oder Polierbänder werden auf Bandschleifmaschinen mit verhältnismäßig großen Geschwindigkeiten bewegt, so daß an den Umlenkrollen dieser Schleifbänder verhältnismäßig große Zentrifugalkräfte auftreten können. Dadurch entsteht die Gefahr, daß bei Bändern mit leicht losreißbarem Schleif- bzw. Polierbelag, z. B. Stahlwolle, der Belag abgerissen oder gelockert wird. Dieser Gefahr zu begegnen, ist Aufgabe der Erfindung.Device to prevent the covering from tearing off all around Grinding or Polishing belts Abrasive or polishing belts are used on belt grinders moved at relatively high speeds, so that on the pulleys relatively large centrifugal forces can occur on these grinding belts. Through this there is a risk that with belts with an easily tearable grinding or polishing layer, z. B. steel wool, the covering is torn off or loosened. To face this danger is the object of the invention.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an den Umlenkrollen von außen gegen Belag des Schleif- oder Polierbandes sich anlegende Stützbänder angeordnet werden, die im Schlepp oder angetrieben mit der gleichen Geschwindigkeit umlaufen wie das Schleif- oder Polierband.This object is achieved according to the invention in that on the pulleys from the outside against the coating of the grinding or polishing belt, supporting belts be arranged towing or propelled at the same speed circulate like the sanding or polishing belt.

Vorteilhafterweise sind die Stützbänder mit Durchbrächen versehen, durch die der abgetragene Schleif-und Polierstaub entweichen kann, wobei die an den Umlenkrollen auftretenden Zentrifugalkräfte für das Austragen des zwischen den einzelnen Stahlwollefasern vorhandenen Schleifstaubes zusätzlich ausgenützt werden. Als Stützbänder eignen sich Bänder aus Drahtgewebe, Drahtgewirke od. dgl.The support bands are advantageously provided with openings, through which the removed grinding and polishing dust can escape, whereby the the pulleys occurring centrifugal forces for the discharge of the between the individual steel wool fibers existing grinding dust can also be used. Belts made of wire mesh, wire mesh or the like are suitable as support bands.

Alles Nähere über die Erfindung ergibt sich aus der nachfolgenden Beschreibung in Verbindung mit der Zeichnung, in der ein Ausführungsbeispiel einer Vorrichtung gemäß der Erfindung - und zwar nur eine der beiden spiegelbildlich gleichen Hälften -dargestellt ist.All details about the invention emerge from the following Description in conjunction with the drawing, in which an embodiment of a Device according to the invention - and only one of the two is mirror-inverted Halves - is shown.

Das Schleifband 1, auf dessen Außenseite die Schleif- und Poliermittel 2 angebracht sind, läuft um die Umlenkrolle 3. Das Stützband 6 wird durch die Rollen 4, die gegebenenfalls auch federnd in Richtung auf das Schleifband 2 gedrückt werden können, auf das Schleifband 2 gepreßt und im Schlepp mitgenommen.The abrasive belt 1, are mounted on the outside of the grinding and polishing means 2 passes around the guide roller 3. The support strip 6 is pressed by the rollers 4, which may optionally also be pressed resiliently in the direction of the grinding belt 2 on the grinding belt 2 and taken in tow.

Die Rolle 5 dient dabei als Umlenkrolle für das Stützband 6. Über die Rollen 4 oder die Rolle 5 kann das Stützband 6 auch gesondert angetrieben werden.The roller 5 serves as a pulley for the support belt 6 the rollers 4 or the roller 5, the support belt 6 can also be driven separately.

Zwischen den beiden Rollen 4 wird das Stützband 6 durch die Schleifbandumlenkrolle 3 geführt, so daß die hier auftretenden Zentrifugalkräfte die Schleif- und Poliermittel 2 nicht vom Schleifband 1 loslösen oder lockern können.Between the two rollers 4 , the support belt 6 is guided through the grinding belt deflection roller 3 so that the centrifugal forces occurring here cannot detach or loosen the grinding and polishing agents 2 from the grinding belt 1.
