TIRE PLY JOINT CONFIGURATION

A method of forming a layer of tire ply is disclosed. A first strip of ply is provided having a plurality of evenly spaced reinforcement cords, having a spacing S, and having a lateral end, wherein the last cord is spaced apart from strip end a distance X, wherein X is not equal to S. A second strip of ply is provided having a plurality of evenly spaced reinforcement cords, having a spacing S, and having a lateral end, wherein the last cord is spaced apart from strip end a distance Y, wherein Y is not equal to S. The lateral ends of the first and second strip are joined together in a lap joint. The first and second lateral ends are overlapped so that the spacing X preferrably does not overlap, but may partially overlap with the spacing Y.
