Abstract: A rewinding machine and a related method, the machine including three rollers having axes parallel to one another and perpendicular to the advancing direction of the paper, where two lower and upper winding rollers collaborate with a third oscillable roller under pressure on a roll or log being formed identifying a winding area, where the paper being wound passes over the upper winding roller and the finished roll comes out from an outlet opening defined between the lower roller and the third roller, where the cores for the rolls are fed one after the other by a conveyor and inserted by a thruster in a channel formed beneath the upper roller, the lower and upper winding rollers being supported in rotation at the ends of their axes in a mobile manner and being associated with an actuator device for a translation in a direction parallel to a first straight line joining the axes of the lower and upper winding rollers and symmetrical with respect to a growth straight line of the roll, where the growth straight line of the roll is arranged perpendicular to the first straight line joining the two axes of the lower and upper winding rollers and equally spaced between them.

Abstract: The present invention concerns a method for joining the ply of a reel of paper in depletion with the initial flap of a new reel, as well as an apparatus adapted for carrying out such a method.Thanks to the method according to the present invention, and to the apparatus suitable for carrying it out, the joining of the reels takes place without using gluing means, like for example the double-sided tape used in known methods, avoiding the relative drawbacks, the adhesion between the plies of the reels to be joined taking place by electrostatic attraction.
