    Abstract: A feeding unit for feeding a plastic film in packaging machines for wrapping paper rolls, including: a unit for unwinding the film from a reel; a cutting device adapted to cut the film transversely; a transfer device including, on the right and on the left side of the feeding unit, drive belts configured for engaging the upper and lower faces of the film; and a positioning device including, on the right and on the left side of the unit, a predetermined number of drive belts configured for engaging the upper and lower faces of the film. On each side of the feeding unit, the transfer device comprises two pairs of belts. On each side of the feeding unit, the positioning device comprises a third pair of belts. The three pairs of belts are actuated by independent actuators.

    Abstract: Feeding unit for feeding a plastic film in packaging machines, including: a unit for unwinding the film from a reel; a cutting device downstream of the unwinding unit and intended to form sheets of predetermined length; a transfer device downstream of the cutting device; a positioning device downstream of the transfer device and comprising drive belts able to engage the upper and the lower faces of the film. The belts of the positioning device are controlled by a control unit connected with optical elements that detect the passage of signs formed on the film. The control unit is programmed to compare a transit time elapsing during the passage of the signs of a same side of two consecutive sheets with a cycle time and to increase or decrease the speed of said belts if the transit time is less than or greater than the cycle time.

    Abstract: A system for packaging groups of paper rolls, including a cutting-off machine that cuts paper logs, each group including rolls obtained from a same log. The system includes: a first unit for arranging the individual rolls spaced apart from each other; a second unit forming the groups by grouping a predetermined number of rolls, the second unit being provided with blades adapted to push from the back the last roll of each group to be formed and each formed group as the individual groups are formed by exerting a pushing action on the rear base of said last roll while the front base and a lateral surface of each roll are free; a third unit located downstream of the second unit and adapted to convey the groups towards a packaging machine.

    Abstract: Packaging machine for packaging paper rolls, including an operating group forming packages, with an entrance station for the rolls and the packaging sheets, and an output station for the packaged rolls; an elevator; a structure on which the operating group is mounted; a plane on which a folder and a counter-folder are formed for folding the packaging sheets under the rolls; a conveyor for moving the packages being formed above said plane; means for welding the packaging sheets; a welding bar for welding the packaging sheets under the rolls. The welding bar is configured to come out through an opening made on the counter-folder and reposition itself below the latter. The carriages are controlled independently of each other.
