The object of the invention is a sharpening device for the blade of a cross-cutting roller (1), in which the cross-cutting roller (1) includes at least one blade plate (4), which is located in the angle formed by the two machined surfaces (2, 3) of the cross-cutting roller in such a way that the original blade bevel (5) is outer and that the blade is sharpened by grinding the original bevel (5) of the blade plate (4) to form less sharp bevel (6) at the edge of the blade plate (4), and in which the sharpening device includes support wheels (7, 10), a grinding stone (8) and devices rotate it. The intention of this invention is to achieve a new kind of sharpening device for the blades of cross-cutting rollers, which makes it possible to sharpen them without removing the blade plates. In accordance with the invention at least one support wheel (7) is adapted to be supported on the original bevel (5) of the blade plate (4) and on the free side surface of the blade plate (4). |
