A rewinding machine (5) arranged to wind a web of absorbent substrate (11) into multiple logs (30) comprising a perforating module (20), a cutting module (21), a winding module (22) and a control module (50), the web of absorbent substrate (11) travelling into said modules according to a machine direction (MD), wherein the perforating module (20) is arranged to provide the web of absorbent substrate (11) with regularly spaced perforation lines (28, 38) substantially transversally orientated relatively to the machine direction (MD), wherein the cutting module (21) is arranged to sever the web of absorbent substrate (11) substantially transversally relatively to the machine direction (MD), wherein the winding module (22) is arranged to wind the web of absorbent substrate (11) so as to produce logs (30) of web of absorbent substrate, and wherein the control module (50) is coupled to the perforating module (20) and to the cutting module (21) and controls said modules operations such that: - at a transition phase (At) between two consecutive logs (30), the control module (50) deactivate the perforating module (20) and activate the cutting module (21), and - out of transition phases (At), the control module (50) activate the perforating module (20) and deactivate the cutting module (21). |
