Abstract (en)
A yarn is continuously wound by a yarn winder without interruption. When a yarn guiding member 73 guides a yarn Y to a tapered portion 71a which is the lower left end portion of a rotational storage drum 71, the yarn Y is wound onto the tapered portion 71a as the rotational storage drum 71 rotates and moves rightward and upward along the surface of the tapered portion 71a, with the result that the yarn Y is stored in the rotational storage drum 71. The yarn Y unwound from the rotational storage drum 71 passes through a gap between a rubber-made annular component 81 wrapping up the rotational storage drum 71 and the surface of the rotational storage drum 71 and runs toward a winding section 6. Furthermore, an airflow flowing from the rotational storage drum 71 side to the upper yarn guide pipe 26 side is generated by a blowdown nozzle 74 in the yarn guiding member 73 and the rotational storage drum 71 is rotated in a direction opposite to the direction at the time of winding the yarn, so that the yarn end of the yarn Y on the rotational storage drum 71 is sucked and drawn out to the upper yarn guide pipe 26.
