摘要:
In a method for producing an unvulcanized ring-shaped rubber member a front edge portion of a band-like rubber member conveyed by a conveyor is disposed on an outer circumferential surface of a forming drum, and the forming drum is rotated to wind a length of the band-like rubber member on the outer circumferential surface and a rear edge portion is held by rear edge holding portions arranged side by side in a width direction. Using distribution data on a length of the band-like rubber member in the width direction, an amount of movement of movement portions in a front-rear direction is controlled to adjust the degree of elongation around the held portion of the rear edge portion in the front-rear direction that is held by each of the rear edge holding portions, and the front and rear edge portions are bonded to produce a ring-shaped rubber member.
