PURPOSE:To dress and remove only projections of a grindstone via an appropriate dress quantity by providing a means which detects that a dresser is brought into contact with the surface of the grindstone except projections and outputs a signal driving a longitudinal feed means. CONSTITUTION:A dresser 16 is moved based on the combined information of the information on end positions of projections, e.g. ear sections 1b and 1c, of a grindstone 1 and the information when the dresser 16 is brought into contact with the grinding surface of the grindstone 1, and only the ear sections 1b and 1c of the grindstone 1 are dressed and removed. The strip grinding surface of the grindstone 1 is not dressed, thus grinding can be performed by the grindstone 1 without damaging a strip. The dresser 16 itself is brought into contact with the grindstone 1 and directly measures the depth of the ear sections 1b and 1c, thus the ear sections 1b and 1c can be dressed via an adequate dress quantity and correctly removed without being affected by the elastic deformation of the grindstone 1 and the thickness fluctuation of the strip. |
