1. A method for controlling a nozzle discharge slot of a flat film machine with an adjusting device for controlling a discharge thickness of a nozzle discharge slot of a flat film machine, comprising a plurality of adjusting bolts for carrying out an adjusting movement for changing the discharge thickness, wherein the adjusting bolts comprise an adjusting region between a closing end position and an opening end position, wherein further starting from the opening end position, the adjusting region comprises a basic stroke path for a basic adjustment of the discharge thickness and, starting from the closing end position, comprises a process stroke path for process controlling of the discharge thickness, comprising the following steps:
adjusting a starting control value for the discharge thickness on a plurality of adjusting bolts by movement along the basic stroke path;
controlling the discharge thickness based on a preset value by moving the plurality of adjusting bolts along the process stroke path;
wherein the adjusting device performs both the adjusting and the controlling using the same adjusting bolt from the plurality of adjusting bolts at a respective local position.
