Claim One:
1. A process for improving the regulation of a draw frame wherein measuring signals indicating thickness of a fiber sliver are detected at the input and output of the draw frame by measuring elements and processed by a regulating system of the draw frame, said process comprising the steps of: interfacing a fuzzy controller with the regulating system of the draw frame; inputting the measuring signals indicating the thickness of the fiber sliver into the fuzzy controller; inputting various influencing factors not compensated for by the regulating system into the fuzzy controller, the influencing factors having an effect on the measuring signals; linking and weighting the influencing factors with respect to the measuring signals in the fuzzy controller in accordance with fuzzy inference rules based on empirical data established in the fuzzy controller; forming a measuring signal correction value in the fuzzy controller based on the linked and weighted influencing factors; and applying the correction value on line to the regulating system of the draw frame before the measuring signals are processed by the regulating system beyond the elements which generated the measuring signals.
