Abstract
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 the regulating system of the draw frame comprising interfacing a fuzzy controller with the regulating system of the draw frame. The measuring signals indicating the thickness of the fiber sliver are inputted into the fuzzy controller. Various influencing factors which are not compensated for by the regulating system are also inputted into the fuzzy controller, the influencing factors having an effect on the measuring signals. The influencing factors are linked and weighted 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. A measuring signal value is formed in the fuzzy controller based on the length and influencing factors and this correction value is applied on line to the regulating system of the draw frame before the measuring signal is processed by the regulating system beyond the element in the regulating system which generated the measuring signal.
