Automatic Knotting and Package Change Systems
topic
Automatic package change systems on winding machines detect supply package exhaustion and automatically transfer the running yarn end to a new package using knotting or air-splice mechanisms, enabling continuous winding without machine stop for package change, with reserve package magazines holding multiple packages per position extending the interval between operator attendance and with automatic knotter or splicer performance being verified by periodic joint strength testing of automatically made joins.
Role
Maintains winding machine productivity by eliminating the stop time associated with manual package change that represents a significant fraction of winding machine downtime in facilities running fine-count single-end packages with short package life, with automatic package change reducing operator attention requirements and enabling higher operator-to-machine ratios that improve winding room labour productivity.
