Method for Operating a Bale Opener and Such a Bale Opener

Abstract

The invention relates to a method for operating a bale opener ( 1 ) having a stripping element ( 3 ) and a safety device for protection against penetration into a hazardous zone of the stripping element ( 3 ), said safety device consisting of sensory safety means, wherein a monitoring region ( 13, 13 1 , 13 2 , 13 3 ) at the front beneath the stripping element is detected and wherein the stripping element ( 3 ) is mounted on a stripping tower ( 2 ). According to the invention the safety device is at least one two-dimensional laser scanner ( 12 ), on which at least one monitoring region ( 13, 13 1 , 13 2 , 13 3 ), which is adjustable and variable over time, is monitored. The invention also relates to a corresponding bale opener ( 1 ).
