Abstract
A number of sensors, each including a light source, illuminating and imaging optics and a detector, are arranged decentrally on a spinning or winding machine having a number of thread lines to provide online monitoring of the winding quality of a number of bobbins during the production of the bobbins. The sensors are preferably mounted on bobbin changers to traverse back and forth across a plurality of thread lines to examine a plurality of bobbins as they are being wound. These sensors are used on spinning or winding machines equipped with an electronic yarn-clearing system, with an interlinking of the measurement signals.
