Has contact washer, so that an optional EineekmSpace is given. For setting the contact pressure of the sanding belt on the workpiece is the pendulum macaw old of the contact disk via force elements approximately in a vertical position Movable towards the sanding belt. In a particularly advantageous way, the Pendelana is approximately at the same height of the bearing is provided with a vertically protruding arm on the support part, on which the force elements attached to the support part are attached Attack a hit direction that is roughly parallel to the Verkstacktransportriehtung. A force element can convey the contact pressure and, in the end positions of the idler device, the feeding or lifting of the contact disk I) ZW. effect of the sanding belt from the workpiece. This second force element expediently engages Stop part with a longitudinal slot on the boom Fixed adjustable stop determines the end position.

Me tracking device must run smoothly and yet be carefully and precisely managed.

provided that there are two rollers on each side of the car with a vertical axis between two rail strips attached to the frame and two rollers in the middle of the carriage horizontal axis between other rail strips attached to the frame. The on the workpiece surface Coordinated carriage speed is regulated by a force element in the form of a hydraulic cylinder, the one force element for the actual movement of the carriage, which is expediently designed as a pneumatic cylinder is, is superimposed. Pie rails for guiding the car are arranged in a frame. This is with one Connected to the drive motor that drives a drive roller, it also carries a belt tensioning arm for a tensioning roller and a guide roller, the three rollers around which the sanding belt runs, lie together in a manner known per se with the contact disc in one plane

Further details of the invention are based on the drawing, which shows an example embodiment, explained in more detail. Show it :

To adjust the contact pressure of the contact disc 13 the pendulum arm 25 carries a boom 39 which is directed approximately perpendicular to it and at the level of the bearing pin going off. Force elements 40, 41 act on this arm 39 and are designed as air pressure cylinders are connected to the drag part 23 via struts 42, 43. While the force element 40 acts directly on the boom 39 and determines the contact pressure of the contact disk 13, the force element 41 is used to feed or lift the contact disk 13, if this is via the follower device 12 in has reached the end positions. In this case, a stop part 44 is expediently interposed, the one Carries longitudinal slot 45 into which a bolt 46 of the boom 39 engages. The piston stroke or the stroke of the contact disc can be adjusted by a stop 47, e.g. a screw, on the support part 23.

The gate parts achieved with the invention exist in particular in that, using a minimal number of machining stations, workpieces with difficult,
