ABSTRACT:
A system for obtaining position data of cops on a winder while the cops are carried in a direction along a predetermined conveyance path having sections, connections of sections and sections where movement of the cops in a direction from one of the sections to another of the sections is to be confirmed. Ends of yarn of each of the cops are found in a yarn end feeding portion of the winder. The yarn of the cops is unwound from the cops in a plurality of winding-units of the winder. Remaining yarn on any of the unwound cops is detected in a remaining yarn sensing portion of the winder, and yarnless cops are finally discharged from the winder. Sensors detect only the presence of any one of the cops at respective sensor positions along the predetermined conveyance path. The sensor positions are by the connections of sections of the predetermined conveyance path and the sections where movement of the cops in the direction from one of the sections to another of the sections is to be confirmed for obtaining the position data of each of the cops along the predetermined conveyance path.
