29. Abstract of the Disclosure The present invention discloses a tire building apparatus (10) and preferred method for building a tire. The apparatus includes a longitudinally movable carriage (12), a guideway (20) for the longitudinal movement of the carriage, a headstock (14) mounted on the carriage, a tire assembly drum (11) having an inboard end (29) and an out- board end (28), and a drum support (15) mounted on the carriage. A plurality of operation stations (A-G) are spaced longitudinally along the guideway, and mechanical datum (30), fixedly located at each operation station, are provided to engage mechanical locators (31) secured to the carriage. A bladder (42) is provided selectively to cause engagement of the locators with the mechanical datum at each successive station to locate the tire assembly drum precisely with respect to the operation station. The apparatus further includes means (133) to swing the drum support pivotally between an active and passive position, respectively, to engage and disengage a bearing assembly (130) with the hub of the drum, a tailstock (142) movable along a guideway (145) and onto the longitudinally movable carriage, grab segments (186) mounted on the tailstock selectively to deposit and remove annular assemblies (183,188) from the drum, and a stitcher (70) mounted on the carriage.
