ABSTRACT:
A green tire building process comprises: the steps of: jointing both longitudinal ends of a belt-like tread rubber for producing an endless tread band, and applying the endless tread band on an inner periphery of an annular face: jointing both longitudinal ends of a belt-like breaker ply for producing an endless breaker band, and disposing the endless breaker band within said endless tread band with its mid-circumferential plane being aligned with that of said endless tread band; expanding the endless breaker band radially and applying the endless breaker band on the inner periphery of the endless tread band for building a tread breaker assembly; disposing a cylindrical green case within and in coaxial relation with the tread breaker assembly; deforming the cylindrical green case toroidally to be applied on the inner periphery of the endless breaker band for integrally building the cylindrical green case and the tread breaker assembly.
