摘要 A green tire building apparatus comprising a driving section (2); and a building section (1), supported on a shaft extending from the driving section (2), wherein the central former portion (10) of the forming section (1) includes a pair of first former members (11a) and (11b) and a pair of second former members (12a) and (12b) axially movably held on the outsides of the first former members (11a) and (11b), and the width of the central former portion (10) can be lessened to about one-fourth of the maximum width. By use of this apparatus, the width of the central former portion (10) can be set to that required for green carcass shaping and can be lessened to about one-fourth maximum width at the time of toroidal shaping so that the distance between beads (BW3) can be set to that of a mold for vulcanizing, thus greatly reducing wrinkling during the tire building and improving tire quality. <IMAGE>
