Abstract: Rewinder for the production of logs, comprising feeding means adapted to supply a paper web (2), guide means adapted to guide sequentially several cores (1) along a predetermined path between a station (F) for feeding the cores (1) and a winding station (W) in which a predetermined amount of said web (2) is wound on each core (1), winding means (R4, R5, R6) adapted to wind the paper web (2) on the cores (1) in the winding station (W), wherein said guide means comprise a guide (100, 3) with a curved end section (3) that ends in the winding station (W) and that, in cooperation with the winding means, delimits a channel (CH) crossed by each core (1) before reaching the winding station (W). The rewinder comprises means adapted to cyclically modify the shape of the end section (3) of the guide while the winding means carry out the winding of the web (2) on the cores (1) so that, cyclically, the height of a terminal part of the channel (CH) varies between a minimum predetermined value (hi) and a maximum predetermined value (h2). An end part (30; 31) of the curved end section (3) of the guide is connected with an actuator that controls the movement thereof synchronously with the winding means such that said cyclic height variation is determined by the controlled movement of said end part (30; 31) of the curved end section (3) moved by the actuator.

Abstract: Cutting machine for the transversal cutting of logs of paper material, comprising a cutting unit (CU), at least one sharpening unit with two grinding wheels (3) and a device for positioning the grinding wheels. Such device comprises a primary carriage (40, 41; 400) and two secondary carriages (42, 43). The primary carriage has a surface (ST) arranged at a predetermined distance from the plane (P2) of the blade and forming a surface for controlling the run of the secondary carriages. In a first step of positioning the grinding wheels (3), the secondary carriages bring the abrasive side of the grinding wheels into contact with the surface (ST). In a second step, the secondary carriages bring the abrasive side of the grinding wheels to the plane (P2). In a third step, the primary actuators move the primary carriage (40, 41; 400) until the abrasive side of the grinding wheels contacts the blade.
