Abstract:
A method for operating a bale opening machine having a take-off device for removing a desired depth of material in a take-off layer from a top surface of a line of bales as the take-off device passes over the line of bales, said method comprising the steps of:defining a desired normal take-off depth for the take-off device to be applied to all bales of the bale line; computing actual take-off depths at predetermined positions along the bale line as a function of the normal take-off depth and a take-off factor computed for the respective positions, the respective take-off factors having a proportional value within a defined range based on relative bale height at the respective positions; controlling the take-off device as a function of the actual take-off depths for each pass of the take-off device; and subsequently determining a new total height difference between a low bale height and a high bale height and setting the actual take-off depths to eliminate the influence of the take-off factor upon the total height difference being reduced to at least the value of the normal take-off depth.
