This winder is provided with the following: a first rotating body (12) that is rotated by a rotating shaft (11); and a second rotating body (16) that rotates coaxially with and at the same speed as the first rotating body (12). This winder is further provided with a cylinder (14) for opening and closing a space between the first and second rotating bodies (12, 16). A groove (20) in which a wire (W) is wound, forming a bead ring (B), is formed in the outer surface of a joining part of the first rotating body (12) and/or the second rotating body (16). |
