In a device for loading film (3) on machines for wrapping groups of products, there is an area (H) designed to allow the free passage of the film (3) and located between a drive carriage (4) and one end (6a, 7a) of each of the film (3) feed rollers (6, 7). This area is defined by an extension of each roller (6, 7) and is tapered in relation to the circumference of the rollers. The film (3) can pass freely when it has a narrow configuration, in the form of a tongue (C), and when the free end (3a) of the film (3) is inserted and fed along a path (P) parallel to an original feed path. In the area (H) there are means (8) on which the tongue (c) can slide and which guide the tongue onto the contact and sliding surfaces (6s, 7s) of the rollers (6, 7). The invention also concerns a method for loading the film (3).
