| 中文摘要: |
| 针对目前缺气保用轮胎核心部件贴合采用的一次法及二次法成型工艺技术，主要介绍支撑胶和增强层的成型工艺。一次法成型采用自动供料装置，实现自动定长裁断和贴合，贴合精度和效率高，二次法成型支撑胶和增强层采用机外裁断、手动贴合方式，贴合精度和效率较低。 |
| 英文摘要: |
| Aiming at the one-step and two-step building technical used for fitting the core components of run-flat tire，the building technology of support compound and reinforcing layer was mainly introduced.The automatic feeding device was adopted for the one-step building method to realize automatic fixed length cutting and fitting，which had high fitting accuracy and efficiency.The support compound and reinforcing layer built by the two-step building method adopted external cutting and manual fitting，which had low fitting accuracy and efficiency. |
