METHOD FOR FORMING GREEN TIRE, AND METHOD FOR PRODUCING PNEUMATIC TIRE

摘要

A method includes a tubul ar carcass wi th core forming process (K1), a rubber laminate forming process (K2), and a tubul ar base ti re forming process (K4). The forming process (K1) of forming a tubular carcass wi th bead core (6R3) on a fi rst drum (20) comprises a tubul ar carcass forming step (K1a) to form a tubular carcass (6R2) by butt-jointing circumferential end faces of a carcass pl y member (6R1) wound singly on the first drum (20), and a bead core joining step (K1b) to form integrally by diameter-expanding and pressing the tubular carcass (6R2) against the bead cores (5) outserted on the radially outer side. In the forming process (K2), rubber members for base ti re (Ga) including an inner liner rubber member (G10a) are wound on a second drum (27) so as to form a rubber laminate (11). In the forming process (K4), the tubular carcass with bead core (6R3) is transferred from the first drum (20) to the second drum (27), and the rubber laminate 11 is pressed against the tubular carcass with bead cores (6R3) so as to form a tubular base tire (35).
