Sharpening device for sharpening blades mounted on cutting machines, comprising two grinding wheels (2, 3) supported by respective movable supports (20, 30) adapted to move said grinding wheels (2, 3) from a standby or rest configuration in which the grinding wheels (2, 3) are positioned at a predetermined distance from the blade (4) to an active configuration in which the grinding wheels (2, 3) are in contact with a cutting edge (40) of the blade (4) and vice-versa along a predetermined trajectory (R2, R3). The movable supports (20, 30) are adapted to move said grinding wheels (2, 3) along respective arcuate trajectories, such that the contact of each grinding wheel (2, 3) with a respective side of the cutting edge (40) of the blade (4) is progressive, whereby the contact between the grinding wheels and the blade increases progressively when the device passes from the standby rest configuration to the active configuration. |
