Patent number: 11345106Abstract: A single sheet-like belt 8b, from which a single tire component can be formed, is held on an outer circumferential surface of a winding cylinder 12. The sheet-like rubber member 8b, which is held by the winding cylinder 12, is removed from the winding cylinder 12 by rotation of a drum 22 and adhered to an outer circumferential surface of the drum 22, so as to manufacture a tire component 8c. At the time, the sheet-like belt 8b is moved from the winding cylinder 12 to the drum 22 via a removing roller 14 that is arranged above a common tangent Q between the drum 22 and the winding cylinder 12.Type: GrantFiled: December 13, 2018Date of Patent: May 31, 2022Assignee: TOYO TIRE CORPORATIONInventor: Junji Itakura
