A paper bobbin for winding yarn has an outer periphery provided with two annular protruding portions each adjacent to one of two ends of the paper bobbin respectively; since each protruding portion is protruded a height from the outer periphery of the paper bobbin, the two annular protruding portions may help the paper bobbin not only to lower the frequency of fiber breakage at initial stage of a yarn winding operation, but also to contribute to get a high quality of yarn and an increase in yield.

The present invention is an array of sanitary tissue products. The array of sanitary tissue products comprises a first packaged article and a second packaged article. The first packaged article comprises a first rolled sanitary tissue product wound onto a first fibrous core. The second packaged article comprises a second rolled sanitary tissue product wound onto a second fibrous core. The second rolled sanitary tissue product is wound loosely relative to the first rolled sanitary tissue product. The second fibrous core has an axial strength greater than the first fibrous core.

Provided is a wound body formed by winding a long sheet. The wound body is supportable by a support shaft. The support shaft includes a cylindrical outer peripheral part that includes a first projection located at a proximal end and a second projection located at a distal end, and includes an inner peripheral part that includes a first recess part located at the one end and recessing outward in the radial direction and a second recess part located to extend from the one end to the other end and recessing outward in the radial direction. A recessing amount of the second recess part is smaller than that of the first recess part. The support shaft and the core body are integrally rotatable around the central axis by engagement of the first projection with the first recess part in a state where the core body is mounted on the outer periphery of the support shaft. The circumferential position of the first projection around the central axis is aligned with the circumferential position of the first recess part around the central axis by engagement of the second projection with the second recess part when the core body is mounted on the outer periphery of the support shaft.
