Self-propelled wrapping machine

A self-propelled wrapping machine movable around a load for wrapping the load with a plastic film, the self-propelled wrapping machine comprising:

• a self-propelled carriage to move the self-propelled wrapping machine around the load;
• an upright fixed to said self-propelled carriage and slidably supporting a moving slide movable along said upright, said moving slide being provided with a connection assembly;
• a first actuator arrangement to move respectively said self-propelled carriage around the load and said moving slide along said upright;
• an unwinding unit to be provided with a reel of film, said unwinding unit having a roller assembly at least for guiding and unwinding the said film and a quick coupling assembly configured to be coupled to and uncoupled from said connection assembly respectively to mount said unwinding unit on said moving slide in an assembled configuration and to disassemble said unwinding unit from said moving slide in a disassembled configuration;
• a main drive and control system associated with at least one of said self-propelled carriage or said upright and configured to operate and control at least said first actuator arrangement;
• and
• a complementary drive and control system associated with said unwinding unit and configured to operate and/or control at least one of a second actuator arrangement or a third actuator arrangement acting on said roller assembly and to receive and process signals relating to operating parameters of said unwinding unit from a sensor device thereof,
• wherein said main drive and control system and said complementary drive and control system are reversibly electrically connectable to each other by connectors to exchange control signals and transfer electric power supply.
