Claim 9:
10. Method for wrapping a load by means of a self-propelled wrapping machine according to claim 1, comprising a wrapping cycle which includes:
positioning said self-propelled wrapping machine adjacent to said load in a defined initial position;
unrolling from an unwinding unit an initial flap of film by moving a first gripping unit which holds said initial flap from a picking position to a releasing position;
fixing said initial flap unwound from said unwinding unit to a supporting plane on which said wrapping machine moves, by positioning an anchoring element on said initial flap by means of a second gripping unit moved in a lowered position;
releasing said initial flap and said anchoring element disengaging said first gripping unit and said second gripping unit, respectively;
moving said self-propelled wrapping machine around said load for at least one turn, wrapping said load with said film supplied by said unwinding unit;
stopping said self-propelled wrapping machine in said defined initial position and lifting said anchoring element from said supporting plane so as to disengage said anchoring element from said initial flap of film by means of said second gripping unit moved from said lowered position to a raised position;
moving said self-propelled wrapping machine around said load for a defined number of turns and wrapping the load with said film;
stopping said self-propelled wrapping machine in a defined final position and grasping and cutting by means of said first gripping unit a portion of film comprised between said unwinding unit and said load in order to generate an initial flap of film, held by said first gripping unit, and a terminal flap associated with said load.
