Title:

METHOD OF PRODUCING PNEUMATIC RADIAL TIRE

Document Type and Number:

WIPO Patent Application WO/2004/103688

Kind Code:

A1

Abstract:

A method of producing a pneumatic radial tire has a step of forming a tire casing, where, in the step, at least an inner liner, a left and right pair of narrow adhesion sheets, and a carcass layer are wound, in that order from the inside, in a hollow-cylindrical shape on the outer periphery of a shape-forming drum while being pressed by a pressing/adhering roller, and a bead core and a bead filler are set at both left and right end portions of the outermost periphery. The shape-forming drum has circumferential belt-like grooves formed in its outer periphery, at positions corresponding to the positions of the adhesion sheets. A shape-forming drum having an elastic layer coated on its outer periphery can also be used as the shape-forming drum.
