STITCHER DEVICE FOR MOLDING TIRE

PROBLEM TO BE SOLVED: To provide a stitcher device for molding a tire which dispenses with the use of a complicated and expensive drive mechanism and can be reduced in size and cost. SOLUTION: Respective rollers 10 are supported in a freely rotatable manner so that the tangential direction of each of them forms a predetermined inclination angle θ of inclination with respect to the tangential direction of an unvulcanized tire T and also supported so as to be respectively moved toward both end sides in the width direction of the tire from the central side in the width direction of the tire while brought into contact with the unvulcanized tire T due to the inclination. When the respective rollers 10 are moved to the predetermined position in the width direction of the unvulcanized tire T to be released from the contact with the unvulanized tire T, they are moved to a predetermined initial position by the energizing force toward the central side in the width direction of the tire. Accordingly, the respective rollers 10 can be moved in the width direction of the tire without using the drive mechanism such as a motor or the like at both times when the respective rollers 10 are brought into contact with the unvulcanized tire T and the contact of them with the unvulcanized tire T is released.
