Abstract:

To prevent mixing of a yarn poor in quality with a winding package for a product.SOLUTION: A machine base control device 5 of a false-twist texturing machine 1 generates a residual quantity related information which is numerical value information regarding a remaining quantity of a yarn Y remaining in a yarn feeding package Ps1 through an arithmetic operation. The machine base control device 5 controls a cutter of an auto doffer 10 to cut the yarn Y when it is determined that a quantity of the yarn Y included in a winding package Pw reaches a prescribed target winding quantity, and executes forming completion processing for controlling a winding device 19 to complete forming of the winding package Pw. Then, the machine base control device 5 executes replacement processing for controlling the auto doffer 10 to replace the winding package Pw with a new winding bobbin Bw. The machine base control device 5 executes the forming completion processing when it is determined that a numerical value of the residual quantity related information becomes equal to or lower than a prescribed value, thereby causing the winding device 19 to form a winding package Pw3s (forming forcible completion winding package) including the yarn Y smaller in quantity than the target winding quantity.SELECTED DRAWING: Figure 7
