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 cutting-off machine for the transversal cutting of logs of paper material, including a structure on which the logs to be cut are moved and a cutting unit including a support plate for a blade arranged along a lying plane. The machine includes at least one sharpening unit with two grinding wheels for sharpening the blade on opposite sides of the plane and equipped with an abrasive side and a grinding wheel positioning device with respect to the blade, arranged on each sharpening unit, by which each grinding wheel is placed in a position of contact with the blade in a phase of sharpening the latter starting from a position initial inoperative. The positioning device is equipped with automatic elements for detecting the wear of the abrasive side of the grinding wheels.

Abstract: Calender for the treatment of web-like materials, including a fixed structure supporting two heated rollers reciprocally arranged so as to form a nip traversable by web-like materials, where each roller has pins mounted on bearings. The structure includes two lower levers and two upper levers adapted for exerting on the bearings forces oriented according to not coinciding directions, each lever being connected with an actuator that controls its rotation around a horizontal axis to put it in a first engagement position of the respective bearing and in a second release position, such that in the second position of the levers the extraction of the rollers from the calender is allowed.

Abstract: Rewinder for making paper logs of paper material including a detection system with optical means adapted to detect, in a succession of predetermined detection times, a succession of diameters assumed in such times by a log being formed in a winding station and a programmable electronic unit which compares the diameters measured by the optical means with a succession of corresponding preset diameters and to calculate a sequence of differences. The processing unit receives a signal relating to the value of the actual diameter of the completed log and determines a parameter related to the trend over time of the differences. Elements for adjusting the thickness of the paper web automatically adjust said thickness if the parameter is between predetermined values and.

Abstract: Rewinder for making paper logs, including a winding station with a first winding roller and a second winding roller delimiting a nip and a third winding roller downstream of the other rollers. The rewinder includes optical elements for detecting, at a predetermined time, an actual position of each log in said winding station and an electronic unit connected to the optical elements and programmed to compare the actual position with a theoretical position of the log at the time, the electronic unit being connected to at least one motor driving the rollers and programmed to modify the speed of the at least one motor when a deviation between the actual and theoretical positions exceeds a pre-established value, the electronic unit being also programmed to operate said optical elements at the time.

Abstract: Equipment for removing paper from parent reels used for the production of paper logs of paper material, including a support system adapted to support an exhausted parent reel, where the exhausted parent reel includes a tubular core on which residual paper to be removed is wound, and including removal capabilities for removing the residual paper from the core when the exhausted parent reel is placed on the support system. The removal capabilities include a suction cylinder having a horizontal axis onto which the paper is transferred by effect of the contact between the suction cylinder and the exhausted parent reel and by effect of the rotation of the suction cylinder around the horizontal axis.

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).
