Manufacturing method of tire component and manufacturing device of tire component

A manufacturing method of a tire component, the manufacturing method including a process of adhering a sheet-like rubber member that is held in a supply section to a drum, the manufacturing method of the tire component comprising:

• detecting positions of the sheet-like rubber member ends in a width direction using sensors that are provided between the supply section and the drum, moving the supply section in the width direction of the sheet-like rubber member in accordance with the detected positions, and adhering the sheet-like rubber member to a specified position on the drum,
• wherein the sensors provided between the supply section and the drum detect positions of the ends in a width direction of the sheet-like rubber member from the time of the sheet-like rubber member leaving the supply section to the time of the sheet-like rubber member reaching the drum, wherein
• the sheet-like rubber member has a parallelogram shape that includes paired lateral sides and paired inclined sides, the paired lateral sides constituting the ends in the width direction of the sheet-like rubber member and being arranged in parallel with a moving direction of the sheet-like rubber member that is moved from the supply section 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,
• the sensors are provided to be able to detect the positions of both of the lateral sides,
• a tip of one of the paired inclined sides on a tip side of the sheet-like rubber, which is wound around the winding cylinder, is adhered to a specified position on an outer circumferential surface of the drum through the sensors and a removing roller, and
• from the time at which the adhesion of the sheet-like rubber member is initiated to the time at which the sensors detect both lateral sides, the supply section is moved in the width direction of the sheet-like rubber member in accordance with the position of the one lateral side, and after the sensors detect both of the lateral sides, the supply section is moved in the width direction of the sheet-like rubber member in accordance with the position of other lateral side.
