Abstract (en)

An automatic winder 4 includes an acquisition unit 45 configured to acquire information related to quality of yarn 14 travelling from a yarn supply bobbin 11 toward a package 15 and a controller 41 configured to control a winding speed at which yarn 14 is wound from the yarn supply bobbin 11. The controller 41 controls the winding speed, based on a quality index of yarn based on the information related to quality acquired by the acquisition unit 45 and a preset index threshold range related to quality of yarn 14, such that the quality index falls within an index threshold range.
