Abstract (en)
A winding group (10) for winding paper (11') around a core (11) to make a log (11") comprising in an upstream position, means for transporting and introducing the core (11) into a channel (12) defined at the top by an upper winding roller (14), supplied from above with the paper (11') directed towards the channel (12), and at the bottom by a cradle member (13) associated downstream with a lower winding roller (15), the winding group (10) comprising a third oscillating roller (16) arranged above the lower winding roller (15), the three rollers (14, 15, 16) cooperating downstream of the channel (12) to wind the paper (11') around the core (11) to make the log (11"), further being provided cyclic means for tearing the paper (11') moving forward on the upper winding roller (14) to identify a final edge (50) and an initial edge (60) as well as means to cause the initial edge (60) to wind on the core (11) introduced into the channel (12), the cyclic means for tearing the paper (11') comprising a rod member (17) rotating around a pin (18) and provided with a head (20) for cyclic cooperation with the upper winding roller (14) for tearing the paper (11'), wherein the head (20) at least in proximity to the upper winding roller (14) has a greater peripheral speed with respect to that of the upper winding roller (14) to tear the paper (11') upstream of the head (20).
