Abstract

Method of diagnosing failures in a production process of a synthetic filament yarn, in which a first process parameter dependent on the process control is continuously measured and evaluated, and in which as a function of the evaluation or course derived therefrom an indication signal is generated, there being continuously measured and evaluated at least a second reference parameter dependent on the process control, and the indication signal being generated, when an error-typical behavior is found in the first and in at least one additional parameter.
