Abstract
A method of controlling the quality during the production of a plurality of yarns in a corresponding number of identical processing stations (4, 5, 5') is disclosed. This method allows at least one signal (10, 10', 10') to be detected simultaneously and continuously in all processing stations (4, 5, 5') of such a production line, as well as to acquire at least one additional signal (7, 8, 9, 11) in one or more processing stations (4), the so-called reference stations. By correlating all signals acquired in these reference stations, the result of the correlation is evaluated based on the knowledge of possibly existing interdependencies, with respect to one or more typical properties of the furnished product. It is possible to determine therefrom set values for the further influencing of the process in the reference station as well as to obtain indications of the quality of the product.
