A self-propelled wrapping machine (1) movable around a load (100), for wrapping the latter with a film (50) made of plastic material, comprises a self-propelled carriage (2) provided with guide means (5), a column (6) that is fixed to the carriage (2) and slidably supports an unwinding unit (10) of the film, sensor means (11, 12, 13, 21) to detect surfaces (SI, S2,... Sn) and/or external edges (El, E2,...En) of the load (100) in their total extension and along a detection direction (Z) and process related signals, a control unit (20) to receive the signals from the sensor means (11, 12, 13, 21), calculate a peripheral outline (150) of plan maximum overall dimension of the load (100) on the basis of the surfaces (S I, S2,... Sn) and/or external edges (El, E2,...En), detected in their total extension by the sensor means (11, 12, 13, 21), and process a wrapping path (P) of the wrapping machine (1) around the load (100) on the basis of the peripheral outline (150) so as to avoid collisions with the load (100); the control unit (20) controls the guide means (5) to guide the wrapping machine (1) along the wrapping path (P). |
