提高子午线轮胎均匀性的新途径

New Approach to Improving Uniformity of Radial Tire

为提高子午线轮胎的均匀性，胎体采用一定的角度交叉贴合。对胎体采用不同角度的轮胎进行的均匀性对比试验表明，胎体采用４５°角并与带束层角度＋，－交叉贴合的轮胎均匀性最好。

The carcass plies were so applied that the adjacent plies crossed each other at a certain angle to improve the uniformity of radial tires.A uniformity test was made on the tires with the carcass plies applied at different angles.The results showed that the best uniformity of tire was obtained when the carcass plies were applied at 4 5°angle to the radial direction and the top carcass ply was applied in adverse direction with the bottom belt ply.
