摘要

A green tire building apparatus comprising a belt-making mechanism (1), a transfer mechanism (2), a green tire building mechanism (3) and bead-setting mechanisms (4 and 5), wherein the mechanisms (4 and 5) have functions of pressing a ply-turnup bladder, segments (24a) holding a belt-tread assembly (6) are driven by a hydraulic cylinder (24b) and a green-tire takeout mechanism (9) is attached to the transfer mechanism (2). Consequently, necessary components can be minimized in number, so that the apparatus can be simplified in construction. Furthermore, when this apparatus is used for building green tires, defectives due to improper increase in the outer diameters of a tread and belt can be prevented, and moreover, green tires can be efficiently taken out.
