Abstract
The present invention concerns a tearing device of a continuous ribbon of paper material to be supplied on rewinding machines and a method for tearing the same ribbon. The device comprises mechanical tearing means to cause the tearing of the ribbon in correspondence of at least one perforation and weakening line of the same. The mechanical tearing means comprise an interception portion suitable for engaging, at least temporarily, the structure of the continuous ribbon, to cause it to break. The mechanical tearing means are mobile between a non operative position, in which the interception portion does not engage the ribbon, and an operative position, in which the interception portion engages the ribbon transversally until it causes it to break along a respective perforation and weakening line.
