Abstract: An assembly is disclosed for unrolling and pre-stretching stretch film as the film is fed from the assembly to goods/products to be wrapped or packed. The assembly comprises a first member for controlling the unwinding of the film from a spool, and a cutter arranged downstream of the control member for lacerating the film, the assembly further comprising a second member, downstream of the cutter, for preventing return of the film in a direction opposite to that in which the film leaves the assembly. A cutting procedure, according to another aspect of the present invention, comprises the steps of: following an initial stop of the film during which it is cut, the first, control member is unlocked so as to permit the laceration zone of the film to pass downstream of the second, return preventing member. The film then comes to a new stop to complete the cut following relative motion between the assembly and the goods/products to be wrapped or packed.

Abstract: An assembly is disclosed for unrolling stretch film and pre-stretching the film as it is fed from the assembly to goods/products to be wrapped. The assembly comprises a member for controlling the unwinding of the film from a spool, and a cutter arranged downstream of the control member and capable of being operated to lacerate the film, the assembly further comprising, downstream of the cutter, a member for preventing the return of the film in the direction opposite to the one in which it leaves the assembly. The cutting procedure in accordance with the invention envisages, following an initial stop of the film during which it is lacerated, the unlocking of the control member to permit the laceration zone to pass downstream of the return preventing member, and then a new stop of the film to complete the cut following relative motion between the assembly and the goods/products to be packed.
