Abstract: Rewinding machine for producing paper logs by winding a paper web, include: an element 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 pad is mounted on the pad-holder device by an elastic support which deforms elastically, such that the pad moves elastically towards the pad-holder, when it is subjected to a pressure and moves automatically in the opposite direction returning to its previous position when the pad is no longer subjected to a pressure.

Abstract: A cutting machine for the transversal cutting of logs of paper material, including a cutting unit, at least one sharpening unit with two grinding wheels and a device for positioning the grinding wheels. The device includes a primary carriage and two secondary carriages. The primary carriage has a surface arranged at a predetermined distance from the plane of the blade and forming a surface for controlling the run of the secondary carriages. In a first step of positioning the grinding wheels, the secondary carriages bring the abrasive side of the grinding wheels into contact with the surface. In a second step, the secondary carriages bring the abrasive side of the grinding wheels to the plane. In a third step, the primary actuators move the primary carriage until the abrasive side of the grinding wheels contacts the blade.

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.

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.
