Electronic Positive Feed Systems and Yarn Monitoring
topic
Electronic positive feed systems on knitting machines use servo-driven feed rollers on each yarn feeder position delivering precisely controlled yarn lengths per needle cycle, with yarn consumption sensors monitoring actual yarn delivery and comparing against programme values to detect yarn breaks, package exhaustion, and feeding irregularities that cause fabric quality deviations requiring machine stop and operator attention.
Role
Maintains consistent yarn delivery per knitting cycle that determines stitch length and fabric weight uniformity across all feeder positions and throughout production, with electronic feed control providing the stitch length consistency prerequisite for uniform fabric weight and appearance that would be unachievable with passive tensioner-only yarn supply systems on high-speed multi-feeder knitting machines.
