Rewinding machine and method for the production of logs of paper material

A rewinding machine for the production of paper logs obtained by winding a paper web, comprising:

• feeding means for feeding a continuous paper web along a predetermined web feeding path for feeding the paper web with a predetermined feeding speed;
• pre-cutting means adapted to provide a series of pre-cutting discontinuous transverse lines for dividing the web into sheets of predetermined length;
• winding means, arranged in a winding station located downstream of said web feeding means, the winding station having an inlet for the continuous paper web, the winding means being adapted to wind the web for making logs of paper material, the winding means comprising a predetermined number of winding rollers arranged along said web feeding path such that one winding roller of the predetermined number of winding rollers is at the inlet of the winding station;
• and
• sizing means arranged and acting along said web feeding path, the sizing means comprising a glue application pad adapted to cyclically apply glue by contact on the web in the proximity of a pre-cutting line thereof, said pad being mounted on a pad-holder device connected with a corresponding actuator;
• wherein—said sizing means are arranged upstream of said inlet of the winding station;
• and
• said pad-holder device is controlled by the respective actuator such that, when the pad is in contact with the web, the pad is moved by the pad-holder device with a speed lower than the feeding speed of the web along the web feeding path so as to cause a prolonged contact of the pad with the web while the pad and the web move.
