轿车轮胎新型2-1冠带条缠绕方式

New Type 2-1 Cap Plies Winding Method for PCR Tire

为了解决EXTRA FRD88花纹轿车轮胎胎里不平的问题,对冠带条缠绕方式进行优化。新型2-1冠带条缠绕方式在原2-1冠带条缠绕方式的基础上,在胎面中心区域左右两侧各多缠绕一圈冠带条,胎面中心金条区域材料厚度加大,使该区域缺少的材料得到补充,消除因胶料流动而导致的胎里不平问题,提高轮胎外观通过率。新型2-1冠带条缠绕方式实际使用效果较好,且操作方便、简捷。

In order to solve the problem of uneveness on inner surface of PCR tire with EXTRA FRD88 tread patterns,the cap plies winding method was optimized. The new type 2-1 cap plies winding method was based on the original 2-1 cap plies winding method,and additional circle of cap ply was wrapped around the left and right sides of the center area of tread,respectively. The thickness of the material in the central area of tread increased,which made up the lack of material in this area,and eliminated the uneveness on inner surface of tire caused by the compound flow. The appearance quality of tire was improved. The new type 2-1 cap plies winding method had good practical effect,and the operation was convenient and simple.
