ABSTRACT:
A method and an apparatus for operating a bale opening machine having an opening member, wherein the height profile of a row of bales is determined by at least one sensor directed towards the bale surface and is used to control the position of the opening member during the subsequent bale opening. The received signal of the sensor, which is preferably an optical or acoustical sensor or a sensor which operates with radar waves, is processed to obtain a signal corresponding to the hardness of the bales. In addition, the in-feed and, optionally, the penetration of the opening member, is controlled or regulated in accordance with the hardness signal. Various slip-free length measuring devices serve to determine the longitudinal position of the opening member along the row of bales.
