| 中文摘要: |
| 研究帘布厚度均匀性影响因素以及解决方案。结果表明：通过常规工艺参数优化（调整轴交叉值、预弯曲应力等）不能有效提高帘布厚度均匀性；帘布厚度均匀性呈“马鞍形”分布的根本原因是气泡刀行程叠加区域辊筒损伤变形，且更换辊筒是解决问题的根本方法；辊筒更换后，帘布厚度均匀性极差从0.20 mm降低至0.05 mm以下，可满足生产要求。 |
| 英文摘要: |
| The factors affecting the uniformity of cord fabric thickness and solutions were studied.The results showed that by optimizating conventional process parameters（such as adjusting axis crossing values and pre-bending stresses） couldn’t effectively increase unifornity of cord fabric thickness.The fundamental reason for the saddle shaped distribution of unifornity of cord fabric thickness was the damage and deformation of the roller in the overlapping area of the bubble knife stroke，and replacing the roller was the fundamental method to solve the problem.After replacing the roller，the range uniformity of cord fabric thickness decreased from 0.20 mm to below 0.05 mm，which could meet production requirements. |
