PURPOSE:To generate the component orthogonal with the traveling direction in the grinding direction of a work stock and to remove the grinding unevenness of the work stock surface by reciprocating a frame fitted with a stepping pad and belt guide mechanism in the direction orthogonal with the traveling direction of the work stock. CONSTITUTION:A feed stock device 2 is composed by bridging a feed stock belt 2a on rolls 2b, 2c, taken in the equal arrangement relation with the four support shafts 12 providing the four support shafts 5 provided on a sanding frame 4 on a fitting frame 11 and making a turning link 13 revolvable centering around the support shaft 5 across the turning link 13. Roller 14, 15 are pivotally supported by a bearing 16 on the frame 11, a stepping pad device 20 is suspended, a support cylinder 25 is erected on the upper face of the frame 11, a steering roll 30 is oscillatably supported, an endless sanding belt is bridged and an abrasive grain face is press-fitted to the work stock by the stepping pad device 20. The frame 11 is driven via an eccentric shaft by the motor not shown in the figure, turned centering around the four support shafts 5 and to the belt 41 a relative zigzag movement component is given by the combination of its right and left movement component and the traveling of the work stock. |
