ABSTRACT:
A tire manufacturing method enabling a tire to maintain a high quality and a tire manufacturing machine of a simple construction and low cost by which improvement of productivity, saving of energy and reduction of maintenance man-hour are possible is provided. A tire green-case is manufactured on a drum by the steps of winding a ply round the drum; expanding the drum to enlarge its diameter; positioning annular beads held by an inner base holder and an outer bead holder at respective predetermined positions on both sides of the drum; advancing each of the inner and outer bead holders toward the drum with thrust controlled by a control means to drive the beads; retreating the inner and outer bead holders; expanding bladders positioned on both sides of the ply; advancing again each of the inner and outer bead holders toward the drum with thrust controlled by the control means to press the expanded bladder laterally, thereby both sides of the ply being folded back so as to wrap the beads; and pressing the both sides of the ply folded back against a main part of the ply.
