METHOD OF USING CORRUGATED ZERO-DEGREE BELT TO MANUFACTURE TIRE

WIPO Patent Application WO/2018/126552

Kind Code:

A1

Abstract:

Provided is a method of using a corrugated zero-degree belt (14) to manufacture a tire. A belt ply structure comprises a No. 1 belt ply (11), a No. 2 belt ply (12), a No. 3 belt ply (13), a corrugated zero-degree belt (14), and a shoulder wedge (15). In a belt ply structure of an all-steel radial tire, a zero-degree belt has a halved density and is wound in two turns. The upper ply and the lower ply are arranged in a staggered manner, thereby forming a single belt. Since each steel cord is wound in two turns, a strength problem of a joint portion is solved. The belt ply structure realizes restraining and fastening functions of a zero-degree belt ply while reducing costs and a weight of a tire. What is more important is that the entire belt ply is flat and smooth and has a consistent thickness. The belt ply structure can improve high-speed performance and abrasion resistance of a tire. Moreover, circumferential distribution of a framework material is more uniform, thereby enhancing uniformity of the tire and driving comfort.
