A tire manufacturing apparatus for mounting an annular tread on a base tire, the apparatus comprising: a drum to which the base tire is secured; a plurality of conveying means, for holding a plurality of positions on an inner periphery of the annular tread, disposed on a concentric circle with the center thereof being the central axis of the drum and configured to individually convey the annular tread in the direction aligned with the central axis of the drum; a plurality of motors for driving each of conveying means; a plurality of holding means extending aligned with an extending direction of the conveying means for respectively holding each of the conveying means, a moving means for having the plurality of holding means approach or separate from the drum along the central axis of the drum; and a control unit for controlling the plurality of motors and the moving means; characterized in that: the apparatus comprises a detecting means for individually detecting the amount of displacement between a central position in the width direction of the annular tread and a central position in the extending direction, the control unit is configured to individually control the motors such that the central position in the width direction of the annular tread held by each of conveying means is located at the central position in the extending direction of each of the holding means, based on the amount of displacement detected by each of the holding means and; the control unit is configured so that, when the position-displacement-corrected annular tread held by the each of holding means is moved to a mounting position of the base tire by the moving means and is mounted on an outer periphery of the base tire, the control unit controls the conveying speed of the conveying means so as to be equal to the travel speed of the moving means to be separated from the drum by synchronizing each of the motors of the conveying means, so that the plurality of conveying means convey the annular tread to the periphery of the base tire. a drum to which the base tire is secured; a plurality of conveying means, for holding a plurality of positions on an inner periphery of the annular tread, disposed on a concentric circle with the center thereof being the central axis of the drum and configured to individually convey the annular tread in the direction aligned with the central axis of the drum; a plurality of motors for driving each of conveying means; a plurality of holding means extending aligned with an extending direction of the conveying means for respectively holding each of the conveying means, a moving means for having the plurality of holding means approach or separate from the drum along the central axis of the drum; and a control unit for controlling the plurality of motors and the moving means; the apparatus comprises a detecting means for individually detecting the amount of displacement between a central position in the width direction of the annular tread and a central position in the extending direction, the control unit is configured to individually control the motors such that the central position in the width direction of the annular tread held by each of conveying means is located at the central position in the extending direction of each of the holding means, based on the amount of displacement detected by each of the holding means and; the control unit is configured so that, when the position-displacement-corrected annular tread held by the each of holding means is moved to a mounting position of the base tire by the moving means and is mounted on an outer periphery of the base tire, the control unit controls the conveying speed of the conveying means so as to be equal to the travel speed of the moving means to be separated from the drum by synchronizing each of the motors of the conveying means, so that the plurality of conveying means convey the annular tread to the periphery of the base tire.
