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 calender for the treatment of web-like materials, including a fixed structure adapted to support two heated rollers shaped to be connected to the fixed structure, to a drive unit and to a heating system. The calender includes automatic elements for engaging and respectively for disengaging the rollers to and from the fixed structure, the drive unit and the heating system; the automatic elements are controlled by a programmable control unit and each of the rollers has an engaging surface shaped to be engaged by mechanical elements for moving the rollers which move the rollers between the calender and one or more waiting or parking stations while the rollers are at a temperature between 50° C. and 200° C.

Abstract: Rewinder for producing paper logs, comprising a winding station with a first winding roller, a second winding roller and a third winding roller driven by corresponding electric motors, including a detection system capable to detect a succession of diameters of the log being formed in the winding station and a programmable electronic unit connected to the electric motors. The system compares the measured diameters with a succession of corresponding diameters of predetermined value and to calculate a sequence of differences between these values. The electronic unit determines a parameter (a) related to the trend over time of the values. The electronic unit changes the relative speed of the first and second roll depending on the value of the parameter.

Abstract: Device for controlling the sharpening state of a blade (2) having a cutting edge (20) delimited by two sides (21, 22) converging towards a plane (X) that contains the cutting edge itself. The device comprises two control surfaces each of which is in contact with a corresponding side (21, 22) of said cutting edge (20) and is connected with at least one transducer (R1, R2, R4), which produces an electrical displacement signal (S1, S2; S4) proportional to a displacement of the control surface with respect to said plane (X). Furthermore, the device comprises a processing unit (E) that receives said displacement signals (S1, S2, S4) and compares them, emitting an error signal if the comparison produces a value that exceeds a predetermined limit. The processing unit is connected to means (101, 102) for supporting and moving sharpening means (100).

Abstract: Device for sharpening blades of cutting-off machines, comprising two grinding wheels (1) each positioned on a corresponding side of a cutting edge (20) of a blade (2) of a cutting machine. The device comprises means adapted for controlling the symmetry of said cutting edge (20), with a sensor (3) placed at a predetermined distance from a corresponding side of the cutting edge (20. The sensor (3) is adapted to detect possible differences (d) between the lengths (n, p) of the two sides of the cutting edge (20). The sensor (3) is connected to a programmable unit (4) that processes the said difference (d) possibly detected by the sensor (3).
