Abstract: Rewinding machine for producing paper logs (20) by winding a paper web (2), comprising:
 means for feeding a paper web (2) along a predetermined path (F2) at a predetermined feeding speed;
web pre-cutting means (30, 31);
web winding means (R2, R3, R4);
web sizing means, with a pad (60) adapted to cyclically apply glue by contact on the web, the pad (60) being mounted on a pad-holder device (6) connected with a corresponding actuator (61). The pad (60) is mounted on the pad-holder device (6) by means of an elastic support which deforms elastically, such that the pad (60) moves elastically towards the pad-holder (6), when it is subjected to a pressure and moves automatically in the opposite direction returning to its previous position when the pad (60) is no longer subjected to a pressure.
