Provided is a configuration for reliably obtaining the fluff laying effect in a yarn winding machine including a yarn storage device (5). An automatic winder includes a yarn supplying section, a yarn storage device (5), and a package forming section. The yarn storage device (5) winds and stores a yarn (20) of the yarn supplying section. The package forming section winds the yarn (20) pulled out from the yarn storage device (5) to form a package. The yarn storage device (5) includes a yarn storage roller (32) around which the yarn (20) is wound. An outer circumferential surface of the yarn storage roller (32) includes a storage region surface (32e) in which the yarn (20) is wound in an aligned manner, and a pull-out region surface (32f) through which the yarn (20) passes when the yarn (20) wound in the storage region surface (32e) is pulled out toward the package forming section side. A surface roughness of the pull-out region surface, which is a surface that the yarn (20) passing the pull-out region surface (32f) contacts, is greater than a surface roughness of the storage region surface (32e), which is a surface that the yarn (20) wound in the storage region surface (32e) contacts. |
