Abstract
The fluctuations in cross-section of fiber slivers are detected by means of a sensor, and from these detections are derived quality parameters, one of which is based on mass non-uniformity. Measurement signals are compared with a limit value for deviations from the desired weight of the monitored sliver, which limit value is formed as a product of mass non-uniformity and a selectable limit-value factor. Any measurement exceeding the limit value is interpreted as the presence of a thick place in the fiber sliver.
