Abstract:
This ring manufacturing method involves the manufacture of a ring in a continuously variable transmission in which a transmission belt configured by binding a plurality of elements together using endless metal rings is used. After a cylindrical body formed by butt welding band-shaped ends together is cut into a plurality of ring bodies, the ring bodies are rotated in a circumferential direction while being subjected to tensile force, edge parts created by cutting in the outer peripheral sides of the widthwise ends of the ring bodies are removed by pushing a grindstone against the widthwise ends of the ring bodies from the sheet-thickness-directional outer peripheral sides of the ring bodies towards the inner peripheral sides thereof, and edge parts created by cutting in the inner peripheral sides of the widthwise ends of the ring bodies are removed by pushing a grindstone against the widthwise ends of the ring bodies from the sheet-thickness-directional inner peripheral sides of the ring bodies towards the outer peripheral sides thereof.
