Abstract
The invention relates to a method for monitoring the quality of a yarn on a textile machine, wherein the yarn passes a monitoring unit of the textile machine, with the aid of which at least one measured variable (M) which is dependent on a physical parameter of the yarn is determined, and wherein the measured variable (M), or a variable derived therefrom, is evaluated with respect to the position thereof with regard to at least one reference value (R). According to the invention, it is proposed that the selection of the reference value(s) (R) takes place taking into account one or more characteristic variables of the yarn, said characteristic variables being yarn-specific and defined prior to evaluating the measured variable (M). Furthermore, a textile machine is proposed which comprises at least one monitoring unit for monitoring at least one physical parameter of the yarn, and at least one controller which is operatively connected to the monitoring unit. The textile machine is characterized in that the controller is configured to monitor the yarn quality according to one or more of the preceeding claims.
