Abstract: 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.

Abstract: A rewinding machine for producing paper logs by winding a paper web, comprising: elements for feeding a paper web along a predetermined path at a predetermined feeding speed; web pre-cutting elements; web winding elements; web sizing elements, with a pad adapted to cyclically apply glue by contact on the web, the pad being mounted on a pad-holder device connected with a corresponding actuator. The web sizing elements are arranged upstream of a web winding station. The pad-holder device is controlled such that, when the pad contacts the web, the pad is moved with a speed lower than the speed of the web along the respective feeding path so as to cause a prolonged contact of the pad with the web while the pad and the web move.
