Abstract
A bale opening machine is provided with a safety apparatus, by means of which there are produced safety barriers or fences parallel to lengthwise sides of a row of bales to be opened and/or substantially perpendicular to the direction of movement of the bale opening machine. The safety apparatus moves in conjunction with the bale opening machine. The safety apparatus can comprise mechanical and/or sensory protective structure. The sensory protective structure comprises one or more electro-acoustical transducers arranged in a sonic chute together with one or more reference reflectors such that transmitted acoustical signals are split into a measuring signal and a reference signal. The reference signal is reflected at one of the reference reflectors, whereas the measuring signal is reflected at a deflection reflector into the monitored area and back again by an object located in the monitored area.
