Abstract:
A device for rewinding and forming a paper roll in a rewinding machine comprising three rollers with parallel axes and perpendicular to the paper feeding direction, wherein two lower and upper winding rollers supported on a frame cooperate with a third swivel roller in pressure on a roll being formed, the paper being wound provided with a series of transverse piercing and weakening lines spaced apart according to regular intervals along their longitudinal development passing on the upper winding roller and finished roll exiting from an output opening defined between the lower roller and the third roller, the cores for the rolls fed one after the other by a conveyor, wherein mechanical tearing means are placed in the upper roller along its development facing towards the side of the paper facing towards the upper roller to positively act directly at a piercing line and cause the tearing of the paper.
