A method for wrapping a palletized load bounded by a vertical lateral face which is closed on itself and two, upper and lower, end faces, by means of film made from plastic. An initial outermost portion of a band of film coming from a reel of film is attached to the lateral face of the load. A relative pivoting movement of the axis of the reel of film and of the load is performed about a first axis which is substantially coincident with the vertical axis of the load and which has a vertical general direction and, as a result of this movement, the band of film is progressively laid over this lateral face. Film is laid over the upper end face to be covered; the band of film is cut transversely and the terminal outermost portion of the band is firmly secured to the laid film or to the load, wherein film coming from the reel of film is laid over the upper end face to be covered and, for this purpose, when the band of film is in the vicinity of the upper end face. At least one pass is carried out in which the relative pivoting movement about the first axis is stopped. A relative pivoting movement of the order of one quarter or of three quarters of a turn of the axis of the reel of film and of the load is performed about a second axis which has a horizontal general direction and the reel of film is thus brought from a sub- stantially vertical position which is parallel to and close to the lateral face of the load to a general position close to and parallel to the upper end face to be covered. The axis of the reel of film then 2 being substantially orthogonal to the second axis; in this situation at least one relative sliding movement of the axis of the reel of film and of the load is performed substantially along the second axis over a travel of the order of the longitudinal dimension of the upper end face of the load measured along the second axis until it is covered with the film. A relative pivoting movement of the order of one quarter or three quarters of a turn of the axis of the reel of film and of the load is then performed about the second axis until the reel of film is brought into a position substantially parallel to and close to the lateral face of the load.
