ABSTRACT:
For the setting of yarn clearers for fineness control the number of permissible false alarms for a given yarn length, i.e. the permissible alarm frequency, is fixed. During the clearing process measured values of the fineness are recorded continuously, and their distribution is determined. From this distribution of the measured values and from the predetermined permissible alarm frequency, response limits are fixed independently on the basis of statistical regularities. Thus, the yarn clearers can be set automatically in an optimum manner on the basis of actual production circumstances, and mistakes between yarns differing only slightly in their fineness cannot occur.
