Abstract

Rewinding method and rewinding machine of a paper web (1) for making a log (2a) comprising a feed roller (3) for feeding the web (1) and a winding cradle (4) in which a log (2a) is formed winding the paper web (1) about a core (20). The latter is supplied into the cradle (4) by introduction means by a loading unit that draws the cores (20) from a chute guide. Upstream from the feed roller (3) a perforation roller (11) is provided that acts in combination with a counter-roller (12) to make a plurality of transversal tear lines (15') on the paper web (1) forming a plurality of panels (16) connected to each other united by the tear line. Upstream from the means for introducing the core (20), furthermore, a gluing means is provided (50) for application of a measured amount of glue (55) on a determined portion of the paper web (1), in particular upstream from (Ia), down-stream of (Ib), or bridging the tear line or clean cut (15). Such lines are made by cutting means, which make either a tear line or clean cut (10''), in coincidence or direct vicinity with the gluing means for applying the glue (50, 10'). The gluing means (50) can, for example, provide a pad (10') that receives the glue by a gluing roller (51).
