<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in uniformity and steering stability. <P>SOLUTION: The method for manufacturing a tire includes steps of (1) extruding a cord together with a topping rubber, to obtain a ribbon 44, (2) winding a sheet around a drum, to obtain a belt 22, (3) feeding the ribbon 44 from a head, to stack a tip end 50 of the ribbon 44 on the belt 22, (4) helically winding the ribbon 44 by rotating the drum while the head is moved in the axial direction toward an end 42b of the belt 22, and (5) winding the ribbon 44 in a circumferential direction by stopping moving of the head, at the end 42b of the belt 22, with rotation of the drum being maintained. In the step of winding the ribbon 44 in the circumferential direction, a rotation angle θs of the drum is greater than or equal to 360°. <P>COPYRIGHT: (C)2013,JPO&INPIT |
