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: Feeding unit (UG) for feeding a plastic film in packaging machines, comprising: a unit (1) for unwinding the film from a reel (2); a cutting device (3) downstream of the unwinding unit (1) and intended to form sheets (SF) of predetermined length; a transfer device (4) downstream of the cutting device (3); a positioning device (5) downstream of the transfer device (4) and comprising drive belts (50, 51) able to engage the upper and the lower faces of the film. The belts of the positioning device are controlled by a control unit (UE) connected with optical means (OC) that detect the passage of signs (T) formed on the film (F). The control unit (UE) is programmed to compare a transit time elapsing during the passage of the signs (T) of a same side of two consecutive sheets (SF) with a cycle time and to increase or decrease the speed of said belts (50, 51) if the transit time is less than or greater than the cycle time.

Abstract: Cartoning machine comprising: a store unit (M) for flat cartons or blanks (F); a blank feeding station (E); an unfolding station (SR) for forming boxes; a feeding station (A) and an insertion station (N) for the products to be packaged. At least two guide blades (202L, 202R) and folding members (206, 207) are arranged in the insertion station (N) for folding the side flaps (PSL, PSR) of the blanks inwards. The blades (202L, 202R) are connected to means which control their positioning in the open position and respectively in the closed position for disengaging the internal faces of said flaps (PSL, PSR). The blades are moved in such a way that, after inserting the products in a box, they are placed in the closed position and subsequently, while the box is moved towards the exit of the machine, they are placed again in the open position for a pre-established time.
