YARN-WINDING DEVICE

To improve freedom of setting change in the winding width in the yarn winding device. In a yarn winding device, a first guide member 63 is configured to move between a non-restriction position at which the lever member 63 does not restrict a movable position of the yarn 4 in a rotational axis direction of the traverse drum 5 to guide the yarn to the traverse drum 5 with a predetermined traverse width, and a restriction position at which the first lever member 63 restricts the movable position of the yarn 4 in the rotational axis direction of the traverse drum 5 to supply the yarn 4 to the traverse drum 5 with a traverse width narrower than the predetermined traverse width, thereby guiding the yarn to different traverse grooves of the traverse drum between the restriction position and the non-restriction position, wherein yarn winding operation with different widths are repeated to perform a step forming winding or a yarn winding operation with a traverse width narrower than the predetermined width is continuously effected to perform a yarn winding with a traverse width narrower than the predetermined traverse width.
