    • The enlargement of a balloon on the spun yarn unwound from the yarn storage section is restrained and broken filaments of the spun yarn are laid down. The upper end portion of a yarn storage drum 27 is shaped as a curved surface portion 65 which is circular curved surface narrowing in diameter toward the upper end side, and an annular component 66 is provided on the curved surface portion 65. The annular component 66 is made of an elastic material such as rubber and is a thin plate arranged so that the difference between the radius at the outer circumference and the radius at the inner circumference is longer than the thickness, and the end portion of the annular component 66 on the inner circumference side is elastically deformed along the curved surface portion 65 so as to surface-contact, in its entire circumference, the curved surface portion 65. A spun yarn Y unwound from the yarn storage drum 27 passes through the gap between the curved surface portion 65 and the annular component 66 and is then running toward the winding section. The spun yarn Y is therefore sandwiched between the curved surface portion 65 and the annular component 66.
