Abstract: A system for handling yarn packages and empty cores. The system includes a winder, a creel and a gripper assembly. The winder is configured to receive an empty core and to wind a predetermined length of yarn onto the empty core to create a yarn package. The creel is configured to provide an array of creel positions for receiving a yarn package. The gripper assembly is configured to be moveable between the winder and the creel. The gripper assembly has a jaw adapted to grip a yarn package when delivering the yarn package from the winder to the creel and to grip an empty core when removing the empty core from the creel and delivering the empty core to the winder. Devices, systems and methods for controlling a yarn tail, loading a yarn spool into a creel, and feeding the yarn through the creel, are also disclosed.
