Manufacturing method of tire component and manufacturing device of tire component

A manufacturing method of a tire component that includes adhering a sheet-like rubber member to an outer circumferential surface of a drum, the manufacturing method of the tire component comprising:

• holding the single sheet-like rubber member, from which the single tire component can be formed, on an outer circumferential surface of a winding cylinder, removing the sheet-like rubber member, which is held by the winding cylinder, from the winding cylinder by rotation of the drum, and adhering the sheet-like rubber member to the outer circumferential surface of the drum,
• moving the sheet-like rubber member from the winding cylinder to the drum via a removing roller that is arranged above a common tangent between the drum and the winding cylinder,
• wherein the sheet-like rubber member has a parallelogram shape that includes paired lateral sides and paired inclined sides, the paired lateral sides being arranged in parallel with a moving direction of the sheet-like rubber member that is moved from the winding cylinder to the drum, and the paired inclined sides being inclined with respect to the moving direction of the sheet-like rubber member at ends in the moving direction, and
• only the sheet-like rubber member of a size that makes it possible to manufacture the single tire component is held around the winding cylinder.
