Description

Schleifmaschinengleitband tt Die Erfindung betrifft eine Schleifmaschine mit Schleifband, das über einen Schleifschuh zur Erzeugung des Anpreßdruckes geleitet wird. Grinding machine sliding belt tt The invention relates to a grinding machine with sanding belt, which is passed over a sanding shoe to generate the contact pressure will.

Bei Schleifmaschinen dieser Art wird der Schuh Schuh gegen di. Rückseite des laufenden Scbleifbandes gepreßt, um dem Werkstück, z.B. Spanplatte, zwischen Schleifschuh und Gegendruckwalze eine genau definierte Stärke zu geben.With grinding machines of this type, the shoe is shoe against di. back of the moving lead tape in order to hold the workpiece, e.g. chipboard, between To give the sanding shoe and counter pressure roller a precisely defined strength.

Zur Versinderung der Reibung1 die dabei zwischen dem Schleitschuh und dem Schleifband auftritt, wird der Schleifschuh Mit einem Gleitband bestückt, welches mit einem Schmiermittel, meistens Graphit, eingeschmiert ist. Dabei ergibt sich aber, daß die Graphitteilchen als Abrieb der Gleitbandes sich iii Laufe der Zeit auf das Gewebe des Schleifbandes übertragen, sich dort festsetzen und unrege1-äßige Erhöhungen bilden.To reduce the friction1 between the shoe and the sanding belt occurs, the sanding pad is equipped with a sliding belt, which is smeared with a lubricant, usually graphite. This results in but that the graphite particles as abrasion of the sliding tape iii the course of the Time is transferred to the fabric of the sanding belt, where it gets stuck and irregular Make increases.

Dadurch ändert sich an manchen Stellen die Dicke des Schleifbandes und damit die gleichbleibende Werkstückstärke, so daß die Oberflächengüte des zu bearheitenden Werkstückes beeinträchtigt wird.This changes the thickness of the sanding belt in some places and thus the constant workpiece thickness, so that the surface quality of the to machining workpiece is impaired.

Der Erfindung liegt die Aufgabe zugrunde, den Schleifschuh bei dieser Art von Schleifmaschinen so auszubilden, daß die gleitende Reibung nicht durch ein mehr oder weniger zähflüssiges Schmiermittel, sondern durch eine Trockensubstanz herabgesetzt wird.The invention is based on the object of the sanding shoe in this Kind of grinding machines should be designed in such a way that the sliding friction is not caused by a more or less viscous lubricant, but by a dry substance is reduced.

Das wird erfiudungsgenäß dadurch erreicht, daß der Schleifschuh mit einem Gleitband versehen wird welches mit einer anorganischen Substanz beschichtet ist, deren kristalline Plättchenform die Reibung des Schleifbandes vermindert, ohne aber die Nachteile eines Schmiermittels zu haben. Als enorganische Substanz, die diesen Effekt bewirkt, wird Magnesiumsilikat (Talkum) verwendet.This is achieved according to the invention in that the sanding shoe with a sliding band is provided which with an inorganic substance is coated, the crystalline platelet shape of which reduces the friction of the sanding belt, but without the disadvantages of a lubricant. As an inorganic substance, Magnesium silicate (talc) is used to achieve this effect.

Wie Versuche gezeigt @@aben, verhindern die Magnesiumsilikatkristalle die Reibung beim Schleifvorgang, ohne daß aber die Gefahr besteht, daß die Gewebefläche des Schleifbandes verschmutzt wird.As shown by experiments, the magnesium silicate crystals prevent the friction during the grinding process, but without the risk of damaging the fabric surface the sanding belt becomes dirty.

In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.An example embodiment is shown in the drawing.

Fig. 1 zeigt im Prinzip die Schleifmaschine; Fig. 2 zeigt den Schleifschuh mit den Belag. Fig. 1 shows in principle the grinding machine; Fig. 2 shows the sanding shoe with the topping.

Das Schleifband 1 wird über die Rollen 2 und 3 geführt, wobei zwischen den Rollen der insgesamt mit 4 beseichnete Schleifschuh angeordnet ist, über den das Schleifband läuft. Der Schuh driickt das Schleifband auf das zu bearbeitende Werkstück, z.B. die Spanplatte 5, die über die Gegendruckrolle 6 läuft.The sanding belt 1 is guided over the rollers 2 and 3, with between the rollers of the total of 4 denoted sanding shoe is arranged over the the sanding belt runs. The shoe presses the sanding belt onto the material to be processed Workpiece, e.g. the chipboard 5, which runs over the counter-pressure roller 6.

Wie Fig. 2 zeigt, besteht der Schleifschuh aus der Halterung 7 und dem eigentlichen Schleifschuhstück 8.As FIG. 2 shows, the sanding shoe consists of the holder 7 and the actual shoe 8.

Dabei ist der Schleifschuh mit einem Belagband 9 versehen, wobei zwischen der Schleiffläche 10 und dem Belagband 9 eine Filzschicht 11 angeordnet ist. Das Belagband ist mit einer Gleitmittelschicht versehen, die aus aufgeschichtetem Nagnesiumsilikat (Talkum) besteht. Die Kristalle dieses Magnesiumsilikates haften an dem Belagband und vermindern die Reibung zwischen des Schleifband und den Schuh.The sanding shoe is provided with a covering band 9, with between a layer of felt 11 is arranged on the grinding surface 10 and the covering belt 9. That Covering tape is provided with a layer of lubricant made of layered magnesium silicate (Talc). The crystals of this magnesium silicate adhere to the covering tape and reduce the friction between the sanding belt and the shoe.

Die anorganischen Substanzen zur Verminderung der Reibung können auch mit eines Bindemittel, z.B. für diesen Zweck besonders prMpariertem Haut leim oder geeigneten Kunstharzen, versehen sein.The inorganic substances to reduce friction can also with a binding agent, e.g. skin glue specially prepared for this purpose or suitable synthetic resins.
