ABSTRACT:
A device for cutting and fixing plastic film in machines for wrapping pallets comprises: means for spacing (1) at least one layer (2a) of the film (2) at a distance from the rest of the wrapping already applied to the pallet (13) so as to create an empty compartment (16) between said layer (2a) and the pallet (13); means for deforming (4; 17) said layer (2a) of film (2), able to render possible the access to the compartment (16); means for cutting (3) the film (2); means for withholding (8) the film (2) in the proximity of at least one end (7) of the cut film (2); and means for pushing (6) the end (7) of the cut film (2) within the compartment (16). A sequential process enables activation of the aforesaid device so as to perform the corresponding operations in series.
