Abstract
A manufacturing device for an unvulcanized band-shaped rubber member is provided. A position sensor detects, across a width direction of the band-shaped rubber member, leading and trailing ends of the band-shaped rubber member placed in a flat state on a conveyor, holding portions arranged side by side in the width direction hold at least one of the leading or trailing ends, with movement portions allowing the holding portions to move individually in a front-rear direction, the leading and the trailing ends are held by the leading and trailing end holding mechanisms, respectively, and a control unit controls a displacement of the movement portions in the front-rear direction based on data from the position sensor and a target length to adjust elongation in the front-rear direction at or near a held portion held by each of the holding portions to achieve the target length of the band-shaped rubber member.
