A portable wrapping machine comprising a movable frame for moving along a track of a facility, with the frame defining an interior space. A wrapping arm assembly is connected to the movable frame for encircling a full pallet located within the interior space to wrap the full pallet with wrap film. A fence system is connected to the movable frame for surrounding the interior space from before initiation of a wrapping process until the wrapping process is complete, the fence system including a pair of fixed side fences and a pair of movable gates. Each of the movable gates being raised during movement of the portable wrapping machine. Each of the movable gates also is lowered to thereby surround the interior space of the portable wrapping machine with the fence system while the wrapping arm assembly encircles the full pallet to wrap the full pallet in wrap film.

A method for controlling the movement of an operating assembly of an apparatus for the automatic processing of articles includes defining, for at least one segment of the movement trajectory of the operating assembly, an acceptable deviation from the movement trajectory, such that the operating assembly can be moved in safe conditions, arranging an auxiliary guide element at a safety trajectory which is alongside the movement trajectory at a distance substantially equal to the deviation, and moving the operating assembly by means of at least one electric motor along said movement trajectory. If the operating assembly moves away from the movement trajectory by a distance equal to said deviation, the auxiliary guide element abuts the operating assembly, controlling its movement and guiding it along the safety trajectory.
