ABSTRACT:
A bale wrapper is provided that comprises a rotating arm holding a film dispenser. The arm rotates around an axis thereby wrapping the film from the film dispenser around the bale. Rotation of the arm is stopped when a sensing arrangement mounted ahead of the arm senses an obstacle. The arm is driven with a first speed sufficiently slow to prevent any risk of injury and the arm and the film dispenser from being damaged by hitting an obstacle detected by the sensing arrangement when an obstacle sensor observing a sensitive range in the environment of the bale wrapper detects an obstacle. The arm rotates at a second speed faster than the first speed when the obstacle sensor detects no obstacle.
