PURPOSE:To prevent the risk that a feeding belt comes in contact with an endless sanding belt and is thus ground, and the risk of breakage accident of the feeding belt, when a thin plate work material is not fed, since the height of the feeding path is extremely short when the work material runs in the path. CONSTITUTION:A feeding roller 20 is provided directly beneath a part to be ground. A feeding belt 6 is hooked over at least a plurality of bypass guide rollers 21a, 21b, 22a, 22b, which are provided before and after the feeding roller 20. Since the feeding belt 6 is thus bypassed down the roller 20, even when the height of a feeding path becomes short, there is no possibility that the feeding belt 6 comes in contact with an endless sanding belt. |
