Abstract (en)

Contamination of a wound package that is a product with a low-quality yarn is avoided. A machine controller 5 of a false-twist texturing machine 1 generates, by calculation, remaining amount-related information that is numerical information regarding the remaining amount of a yarn Y remaining in a yarn supply package Ps1. When determining that a yarn Y in a wound package Pw reaches a predetermined target wound amount, the machine controller 5 performs a formation termination process so that a cutter of an automatic doffer 10 is controlled to cut the yarn Y and a winding device 19 is controlled to terminate the formation of the wound package Pw. Thereafter, the machine controller 5 performs a replacement process to cause the automatic doffer 10 to replace the wound package Pw with a new winding bobbin Bw. When determining that the numerical value of the remaining amount-related information becomes not larger than a predetermined value, the machine controller 5 performs a formation termination process to form, at the winding device 19, a wound package Pw3s (formation forcible termination wound package) having a smaller amount of the yarn Y than a target wound amount.
