ABSTRACT:
In a method and apparatus for the detection of yarn defects, which may be effected in combination with a standard yarn clearer or independently thereof, the cross section of the yarn is continuously scanned and an electrical signal is generated representing not only the cross section and length of yarn defects, but also their frequency or periodicity, and these features are used as the criterion for generating a defect signal as an indication of detection of regular or irregular sequences of thick places in the yarn.
