(54) Yarn winding device


(57) A yarn winding device includes a winding section (17), a winding-angle pattern storage section (72), and a winding control section (73). The winding section is adapted to wind a yarn (20) around a winding bobbin (22) to form a conical package (30). The winding-angle pattern storage section is adapted to store a winding-angle pattern that associates a thickness of a yarn layer of the package with a winding-angle. The winding control section is adapted to control the winding section so as to wind the yarn with the winding-angle determined in accordance with the winding-angle pattern stored in the winding-angle pattern storage section.
