摘要： This invention relates to a pneumatic radial tire, its production, an apparatus for forming a band of a radial tire and a method and an apparatus for molding a belt-band-tread rubber assembly. The pneumatic radial tire is equipped with a belt disposed outside a carcass in a radial direction of a tire and a band disposed outside the belt in the radial direction of a tire and the band consists of one or a plurality of continuous organic fiber cords wound substantially in parallel and spirally in the circumferential direction of a tire. The method of producing the radial tire includes the steps of laminating a predetermined number of belt plies on a belt ring or on a belt drum for molding the belt and winding continuously and spirally one or a plurality of organic fiber cords on the outer peripheral surface of the belt, on which the band is formed, in the circumferential direction thereof. The apparatus for forming the band is equipped with means for paying out the cords to be wound, traverse means for traversing this pay-out means in the widthwise direction of the belt and traverse control means for controlling traverse of the delivery means. The method of molding a belt-band-tread rubber assembly includes the step of expanding the diameter of the belt drum so that the sectional shape of the belt drum in the axial direction is the same as, or approximate to, the final finish shape inside a vulcanization mold of the band. The apparatus for molding this assembly is equipped with a contractile belt drum consisting of a stretchable molding annular member made of an elastomer and contraction means for contracting the molding annular member, and the outer circumferential surface of the molding annular member with its diameter expanded exhibits at its axial direction section a shape the same as, or approximate to, the final finish shape of the band inside the mold, and defines the winding surface of the band.
