 gleichmässige Bearbeitung erfährt. Diese weiche Filzunterlage drückt sich bei der Arbeit leicht zusammen und muss daher öfter gewechselt werden. Sie darf keine Falten bilden. 



   Gemäss der vorliegenden Erfindung wird der Filzunterlage die Form eines endlosen Bandes gegeben, das über zwei Stützen geführt ist und durch Vergrösserung der Entfernung dieser Stützen gespannt werden kann.   Zweckmässig   haben die Stützen die Form von Rollen, um die Verstellung des Bandes zu erleichtern. Bei dieser Einrichtung kann das Band sehr leicht straff gehalten und die Auflagestelle bequem gewechselt werden. Die Spannung des Filzes kann so gewählt werden, wie es für das in Arbeit befindliche Werkstück am günstigsten ist und man kann das Filzband ohne Abfall völlig ausnutzen. 



   In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt. 



   Das Gestell 1 trägt den Schleifzylinder   2,   gegen den das auf der schwingenden Werkstückauflage liegende Werkstück 3 durch Niedertreten eines Hebels   4   gepresst werden kann. Die Rückseite des Werkstückes liegt an einem Filzband 5 als Werkstückauflage an, das über zwei Walzen 6,7 geführt ist. Die Walze 7 ist an Gelenkarmen 9 gelagert, durch welche Schrauben 8   hindurchgeführt   sind, die gegen einen Vorsprung des die   Werkstückauflage   tragenden Schwinghebels 10 drücken. Durch Verstellen dieser Schrauben 8 kann die Spannung des   Bandes o verändert   werden. Die Walze 7 ist zweckmässig kleiner als die Walze 6, damit der Arbeiter nicht beim Bedienen der Maschine gestört wird. Eine Schutzkappe deckt den oberen Lauf des Filzbandes.

   Statt der Walzen 6,7 konnten auch sattelförmige Auflager benutzt werden, auch kann die Vorrichtung zum Spannen des Filzbandes anders ausgebildet sein.

 experiences even processing. This soft felt pad compresses easily when you work and therefore has to be changed more often. It must not form wrinkles.



   According to the present invention, the felt pad is given the shape of an endless belt which is guided over two supports and can be stretched by increasing the distance between these supports. The supports are expediently in the form of rollers in order to facilitate the adjustment of the belt. With this device, the tape can be kept taut very easily and the support point can be easily changed. The tension of the felt can be selected as it is most favorable for the workpiece in progress and the felt belt can be fully utilized without waste.



   In the drawing, an embodiment of the subject matter of the invention is shown schematically.



   The frame 1 carries the grinding cylinder 2, against which the workpiece 3 lying on the oscillating workpiece support can be pressed by stepping down on a lever 4. The back of the workpiece rests against a felt belt 5 as a workpiece support, which is guided over two rollers 6, 7. The roller 7 is mounted on articulated arms 9, through which screws 8 are passed, which press against a projection of the rocker arm 10 carrying the workpiece support. By adjusting these screws 8, the tension of the belt o can be changed. The roller 7 is advantageously smaller than the roller 6 so that the worker is not disturbed when operating the machine. A protective cap covers the upper run of the felt belt.

   Instead of the rollers 6, 7 it was also possible to use saddle-shaped supports, and the device for tensioning the felt belt can also be designed differently.
