METHOD AND DEVICE FOR MEASURING SHAPE OF TIRE MOLDING BODY, AND TIRE MANUFACTURING METHOD

摘要

To provide a method and a device for measuring a shape of a tire molding body capable of grasping a shape of a tire molding body arranged on an outer peripheral surface of a rigid core by utilizing a movable member for movably supporting the rigid core, and to provide a tire manufacturing method capable of manufacturing a tire having high quality.SOLUTION: A method for measuring a shape of a tire molding body includes: calculating a surface shape of a tire molding body 18 at a predetermined molding stage with a calculation part 7 by using separation distance data between a non-contact distance sensor 6 and a surface 18a acquired in a desired range of the surface 18a of the unvulcanized tire molding body 18 at the predetermined molding stage from during molding of being arranged on an outer peripheral surface 2b of a rigid core 2 to molding completion, by moving at least the rigid core 2 among non-contact distance sensors 6 and the rigid core 2 that is movably supported by a free arm 3; and vulcanizing the molding-completed tire molding body 18 by a vulcanization device 11.SELECTED DRAWING: Figure 8
