PROBLEM TO BE SOLVED: To minimize the lifting amount of a sanding mechanism. SOLUTION: A pedal pressure pad 24, an opposite rotation regulating roll 35, and a hopper auxiliary plate 28 protrude more downwards than a sanding mechanism 15 under a free condition, however, air cylinders 42, 62, 52 for raising them are provided. At the time of feeding a work W in the opposite direction, the sanding mechanism 15 rises, and the pedal pressure pad 24, the opposite rotation regulating roll 35 and the hopper auxiliary plate 28 retreats more upwards than the sanding mechanism 15 to avoid interference with the work W. Its rising amount is decreased more than in the case of raising only the sanding mechanism 15. |
