PROBLEM TO BE SOLVED: To prevent a surface layer of a plate from being removed, in an end part of the layered plate molding plate. SOLUTION: In a polishing method of a layered plate molding plate 10, it is polished by a buff roller 1 by supplying the layered plate molding plate 10 between the buff roller 1 and a backup roller 2. The point of time a front/ rear end of the layered plate molding plate 10 leads to a reference position set to before the buff roller 1 is detected by a sensor 4. Length of a moving distance of the layered plate molding plate 10 is measured by a rotary encoder 3. Contact timing of the backup roller 2 with the layered plate molding plate 10 is controlled, based on a measurement result by the sensor 4 and the rotary encoder 3 so as to prevent pressing force by the backup roller 2 from acting in an end part of the layered plate molding plate 10. |
