Claims

[Claims for Utility Model Registration] 1. A belt grinding unit in which a sanding frame supports forming rolls that are driven and rotated in conjunction with a drive source and guide rolls, and a grinding belt is stretched around the group of rolls. In a belt grinding device in which the forming roll is brought into pressure contact with the processing surface via a grinding belt, guide protrusions are formed along the longitudinal direction on the back surface of the grinding belt that is elastic in the vertical and horizontal directions, and the forming roll is A belt grinding device characterized in that a guide circular groove into which the guide protrusion fits is provided around the belt. 2. The sanding frame is equipped with a belt grinding unit in which a forming roll that is driven and rotated in conjunction with a drive source and a guide roll are supported, and a grinding belt is stretched around the group of rolls, and the forming roll is connected to the grinding belt. What is claimed is: 1. A belt grinding device which is in pressure contact with a processing surface through a belt grinding device, characterized in that a grinding belt is stretchable only in the longitudinal direction, and through holes are arranged in rows on both sides of the grinding belt.
