Abstract: A cutting machine for the transversal cutting of paper material logs, including: a structure on which are moved the logs; a cutting unit including a blade; at least one sharpening unit with two grinding wheels; a positioning device for positioning the grinding wheels with respect to the blade. The positioning device includes: a primary carriage and two secondary carriages supported by the primary carriage; a sensor for detecting the radius of the blade and configured to stop the primary carriage when the grinding wheels are arranged with the respective axes at a given distance from the axis of the blade. In a second phase of positioning the grinding wheels, the secondary carriages are controlled so as to bring the abrasive side of the wheels into contact with the blade.

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.

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: 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: Rewinding machine for the production of logs of paper material, including a winding station in which is fed a paper web and, in sequence, more tubular cores, and in which station winding are arranged a first, a second and a third winding roller cooperating with each other to wind a predetermined amount of said paper web onto each core. The machine includes a fourth winding roller which is connected to respective moving elements adapted to arrange it in a first inoperative position until the diameter of a log in the winding station is lower than a first predetermined value and a second operating winding position when the diameter of the log being formed is equal to said first predetermined value, the moving elements being controlled to maintain the fourth roller in the second operating winding position until the diameter of the log reaches a second final value higher of the first predetermined value.

Abstract: Rewinder for the production of paper logs adapted to guide and transversely pre-cut a paper web along a predetermined path, adapted to wind a predetermined amount of the paper web on a core in a winding station, and including a threading mechanism for threading the web along said path. The threading mechanism includes a dragging unit provided to engage the web to drag it along the path with a predetermined feed direction and at least one dragging member to engage a respective flap of the web preceding the production of the logs. The dragging unit is located downstream of the winding station and is adapted to release the flap of the web from the dragging member, the release means being arranged downstream of the dragging so as to intercept the flap of the web and disengage it from the dragging while the web is fed.
