<p>A rewinding machine for creating logs (R) of web material (N) wound around a tubular core (A) comprises web feeding means for feeding the web material to a first winder roller (12) which together with a second winder roller (20) defines a winding cradle (21), core insertion means (40) for placing a tubular core in said winding cradle (21), and web interruption means (70) for severing the web material when a log is completed. The tubular core is introduced in a region (50) upstream, with respect to the web advance direction, a runner (60) made between the first winder roller (12) and the second winder roller (20) and in such region takes place the severing of the web, thanks to the web interruption means (70) that also support the cores in said region (50) keeping them in contact with the first winder roller (12). The rewinding machine of the invention has high reliability, has an optimized structure of the log change assembly and comprises adjusting means that make it suitable to process a wide range of logs and tubular cores sizes.</p> |
