Abstract

Method of monitoring the quality of an advancing yarn by continuously measuring the yarn tension, which includes determining the progression of the yarn tension upon occurrence of a defined failure (failure record), storing the failure record in a data memory, comparing the measured yarn tension with the failure record and generating an alarm signal, when a range of the yarn tension progression shows a similarity to the failure record.
