Abstract (en)
A yarn winding unit (1) includes a yarn supplying section (2) that supplies a yarn (Y), a winding section (12) that winds the yarn (Y) into a package (2), the winding section including a winding drum that makes contact with an outer peripheral surface of the package (P) and rotates, a yarn running speed detecting section (10) that detects a speed of the yarn (Y) running between the yarn supplying section (2) and the winding section (12), and an error detecting section (14a) that calculates a speed ratio by dividing the yarn running speed by a circumferential speed of the winding drum (16), and detects presence/absence of a winding error based on the speed ratio.
