ABSTRACT:
In a method and apparatus for monitoring a yarn winding production process, the traversing amplitude and/or the traversing frequency are monitored by a cross-winding monitoring system, which supplies cross-winding signals over electrical lines to a control and information device, in which the signals are linked with set-point values and/or signals characterizing the winding operation. Conclusions are drawn from the linkage results as to a plurality of characteristics of the winding process, such as misfeeds, drum laps, bobbin laps, ribbon winding state, yarn tensioner function, yarn tension change, drum malfunction, cheese grading, type of cross-winding system and quality of the cheese.
