Abstract
A green tire forming apparatus comprises a belt forming mechanism (1), a transferring mechanism (2), a green tire forming mechanism (3), and bead setting mechanisms (4), (5); wherein the bead setting mechanisms (4), (5) have a function of pushing ply turn-up bladders, segments (24a) holding a belt-tread assembly (6) are driven by hydraulic cylinders (24b), and a green tire take-out mechanism (9) is added to the transferring mechanism (2). Accordingly, the number of elements required can be minimized, so that the structure of the apparatus can be simplified. In addition, when a green tire forming is carried out with the apparatus, production of defective tire due to undesirable expansion of the outer diameters of belt and tread can be prevented, and also green tire take-out can be carried out efficiently.
