A manually propelled wrapping machine movable by an operator around a load to wrap the latter with a film of plastic material, comprises a carriage provided with a plurality of supporting wheels and a guiding bar usable by the operator to push and direct the carriage at least along a wrapping path around the load; a column fixed to the carriage and slidably supporting an unwinding unit for dispensing the film; an actuating device for moving the unwinding unit along the column with a specific movement speed; the wrapping machine further includes a first sensor device associated with at least one wheel of said wheels for detecting and measuring a rotation speed of the latter, and a control unit for receiving a signal related to the rotation speed from the first sensor device and calculating an advancing speed of the carriage along the wrapping path and for controlling the actuating device so as to adjust the movement speed of the unwinding unit as a function of the advancing speed so as to wrap the load with a defined wrapping configuration.

A self-propelled wrapping machine movable around a load, for wrapping the load with a film of plastic material, includes a self-propelled carriage with a guide, a column fixed to the carriage and slidably supporting an unwinding unit of the film, a sensor to detect surfaces and/or external edges of the load in their total extension and along a detection direction and process related signals. The wrapping machine also includes a control unit to receive the signals from the sensor, calculate a peripheral outline of plan maximum overall dimension of the load based on the surfaces and/or external edges detected by the sensor, and process a wrapping path of the wrapping machine around the load based on the peripheral outline so as to avoid collisions with the load. The control unit controls the guide to guide the wrapping machine along the wrapping path.
