Description

Die Erfindung betrifft eine Schleifwalze, bei welcher der Schleifpapierüberzug der Schleifwalze radial gegen den Kern der Schleif walze elastisch abgefedert ist. Elastische Zwischenmittel zwischen mit Schleifpapier überzogenen unelastischen Walzenmänteln und ihren Wal2?enkernen sind bekannt. Bei diesen Vorrichtungen wird das Schleifpapier mit besonderen Mitteln auf dem Schleifmantel befestigt, und die elastische Federung ist hier vom Kern auf einen starren Schleifmantel wirksam, so daß letzterer sich als starrer Mantel gegen den Walzenkern federnd bewegen kann.The invention relates to a sanding roller, in which the sandpaper cover of The grinding roller is elastically cushioned radially against the core of the grinding roller. Intermediate elastic means between with Inelastic roll mantles covered with sandpaper and their roll cores are known. With these devices, the sandpaper is attached to the sanding jacket with special means, and the elastic one Suspension is effective here from the core to a rigid abrasive jacket, so that the latter is can move resiliently as a rigid jacket against the roller core.

Die Erfindung besteht darin, daß der elasti-. sehe Belag der Schleifwalze so eingerichtet ist, daß ein schlauchartiges, also endloses Schleifpapierband direkt auf diesen elastischen Belag (z. B. Gummi) geschoben werden kann und sich dort ohne besondere Hilfsmittel selbsttätig zentriert und festhält. Dies wird dadurch erreicht, daß der elastische Schleifwalzenbelag Erhöhungen aufweist, die sich beim Aufschieben des Schleifbandes in axialer Richtung neigen können und, nachdem das Schleifband aufgeschoben ist, sich von selbst wieder aufrichten, wobei das aufgeschobene Schleifband zentriert und festgehalten wird, und zwar ohne jegliche mechanische Hilfsmittel.The invention consists in that the elastic. see the surface of the sanding roller set up like this is that a hose-like, so endless sandpaper tape directly on this elastic Covering (e.g. rubber) can be pushed and there without special aids automatically centers and holds. This is achieved by the elastic The sanding roller covering has elevations, which are in can incline in the axial direction and, after the sanding belt has been pushed on, move away from Erect yourself again, with the slid-on sanding belt centered and held in place without any mechanical aids.

Auf der Zeichnung ist dieErfindung beispielsweise veranschaulicht, und zwar stellen dar: Abb. ι den Querschnitt einer Schleifwalze mit zum Teil aufgeschobenem Schleifband,The invention is illustrated by way of example in the drawing, namely: Fig. Ι the cross-section of a sanding roller with partially pushed-on sanding belt,

Abb. 3, 4 und 5 Ausführungsbeispiele des Schleifbelages.Fig. 3, 4 and 5 exemplary embodiments of the abrasive coating.

Auf der Walze α ist ein elastischer Belag b befestigt, dessen Erhöhungen c radial zur Achse der Schleifwalze angeordnet sind. Das endlose Schleifband b, dessen Innendurchmesser etwas kleiner· gehalten ist als der Außendurchmesser des Belages b, c, wird in der angegebenen Pfeilrichtung (Abb. 1) über die Erhöhungen c geschoben, wobei sich dieselben in axialer Richtung neigen und so selbsttätig der Außendurchmesser des Belages b, c sich verkleinert, was ein Übergleiten des Schleifbandes ermöglicht.On the roller α an elastic covering b is attached, the elevations c of which are arranged radially to the axis of the grinding roller. The endless grinding belt b, the inner diameter of which is kept slightly smaller than the outer diameter of the covering b, c, is pushed in the indicated direction of the arrow (Fig. 1) over the elevations c , whereby the same incline in the axial direction and thus automatically the outer diameter of the Coating b, c is reduced, which enables the grinding belt to slide over.

Nach Aufhebung des in der Pfeilrichtung ausgeübten Druckes auf den Belag b, c gehen die Erhöhungen c von selbst in ihre ursprüngliche Lage zurück, wobei das Schleifband d zentriert und festgehalten wird. Der elastische Belag b, c kann verschiedene Ausführungsformen erhalten, z. B. zapfen-, rillen- oder schwammförmig u. dgl. sein, wie in den Abb. 3,4 und 5 beispielsweise gezeigt ist. After the pressure exerted on the covering b, c in the direction of the arrow has been released, the elevations c automatically return to their original position, with the grinding belt d being centered and held in place. The elastic covering b, c can have various embodiments, e.g. B. cone, groove or sponge-shaped and the like. As shown in Figs. 3, 4 and 5, for example.
