Abstract: A feed-line management system and associated method are presented for controlling flow-rate of at least one material. The system controls a feed driver to control the motion of the feed-line in response to statistical analysis of data received from a contactless speed monitor. The speed monitor may use an image processor to capture images of the feed line, identify features in the images and determine their speed of movement. The system may provide contactless motion control in industrial conditions, for example controlling yarn feeds in the textile industry.
