摘要

Tearing device (1) of a web (15) of paper material to be supplied to unasmáquinas (2) rewinder, said tape (15) continues a series of perforation lines ydebilitamiento transversely spaced according regularly arranged along its own desarrollolongitudinal, said device (1) comprising mechanical tearing means (28) to be placed operative deforms along the longitudinal development of said web (15) to cause tearing estaúltima in correspondence with at least one of said perforation lines and weakening, comprising dichosmedios mechanical tearing (28) at least a portion (29) intercepting engageable at menostemporalmente, a mating surface of said tape (15) continuous paper material a respective roller (17) of a machine (1) rewinder, is apoyasobre to cause breakage along unarespectiva line perforation and weakening being movable such mechanical tearing means (28) entreuna inoperative position in which said portion (29) of interception engaging said belt (15), and functional unaposición, wherein said part (29) intercepting transversely coupled, moving from elrodillo (17), particularly and substantially perpendicular to said mating surface of said tape (15) continuous eventually break along a respective line of perforation and weakening wherein said portion (29) intercepting said mechanical tearing means (28) comprises unapluralidad projections (29a) which develop substantially parallel to each other, said projections (29a) spaced being each other by a predetermined length, in particularly not greater than the width of a respectivaranura (17a) provided on the respective roller (17) of said rewinding machine (2), each being sa ustomer (29a) arranged to engage, in operative position, to a respective opening of the respective perforation line ydebilitamiento of the web (15).
