A method and wrapping apparatus with plastic film curtain is disclosed. Transfer means (12) are described, apt to present a film end edge coming from at least one storage reel (8-8 3 ) to gripper means (21) of temporary winding means (19, 20), through support and presenting means (17), wherein both said temporary winding means (19, 20) and said transfer means (12) translate crosswise (X-X) to a transport line (1) of a load (C) to apply said curtain of plastic film (P), the transfer means (12) being first connected to a moving coupling bar (18) provided with movement drive independent with respect to a movement drive of said temporary winding means (19, 20), said temporary winding means (19, 20) rotating in a first direction to initially accumulate a length of film (P) and then rotating in a second direction to deliver the same length of film (P) during the dragging of said curtain of film (P) by the load (C), and said transfer means (12), connected to said moving coupling bar (18), and said temporary winding means (19, 20) mutually converge in a centreline area wherein a welding and cutting operation of the film occurs to define said wrapping of the load (C). |
