| 中文摘要: |
| 分析轮胎胎面翼胶在挤出过程中的破边问题，发现口型开型比设计、口型进胶口倒角设计和口型温度均为影响因素。通过减小口型开型比、增大口型进胶口倒角高度和深度及口型设定温度，胎面翼胶挤出破边问题得到有效改善。 |
| 英文摘要: |
| The break edge problem of tire tread wing rubber during extrusion was analyzed.It was found that the opening ratio design of die，the chamfer design of the rubber inlet of die and die temperature were the influencing factors.By reducing the opening ratio of the die，increasing the chamfer height and depth of the rubber inlet of die and the set temperature，the extrusion break edge problem of tread wing rubber was effectively improved. |
