(54) Yarn winding device


(57) In a yarn winding device, a package drive motor (41) directly rotates a package (30). A package-diameter obtaining section (52) obtains a current package diameter of the package (30). A deceleration-condition storage section (51) stores therein a plurality of deceleration conditions, each of which is associated with a hypothetical package diameter and used in controlling the package drive motor (41) to decelerate the package (30) to a stop. A unit control section (50) controls the package drive motor (41) to decelerate the package (30) to a stop according to the current package diameter and a deceleration condition associated with a hypothetical package diameter corresponding to the current package diameter.
