A pneumatic tire and an unvulcanized carcass as an intermediate article in its manufacture

摘要

A radial ply pneumatic tire (100), having an unvulcanized carcass (10) as an intermediate article of manufacture, is described. The carcass (10) has a ply (20) and at least two components. The components are selected from one or more of the component types consisting of a sidewall (70), a chafer (60), a liner (50), a whitewall strip (80), a cover strip (90), and a gum shoulder strip (40). The ply has a width (Wp) and a pair of ends (12,14), the distance between the ends (12,14) defining the ply length (L). The ply (20) and the components are preferably laminated to one another and have common ends (12,14) that are radially spliced along a substantially flat plane (P). The flat plane (P) extends through the article across its width. The flat plane (P) is inclined at an angle THETA , THETA being less than 90 DEG , preferably about 80 DEG relative to a radial normal plane (NP) passing through the ply (20) and parallel to the cords (22) and perpendicular to the ply (20). <IMAGE>
