Abstract
Cleaning water CW is supplied to the outer surface of a draining rollfrom a pipearranged above the draining rollthat is in pressure contact with a contact rollvia a polishing belt PB. Accordingly, the cleaning water CW adheres evenly to the outer surface of the draining rollin the longitudinal direction along with the rotation of the draining roll. Then, the cleaning water CW sufficiently adhering to the outer peripheral surface of the draining rollis carried to a contact portionbetween the draining rolland the polishing belt PB, and cleans the abrasive surface of the polishing belt PB. As a result, it is possible to well reduce the occurrence of uneven cleaning on the abrasive surface, and to further improve the polishing effects of a polishing apparatus
