| 中文摘要: |
| 对全钢子午线轮胎压延钢丝帘布幅宽收缩率进行统计分析，寻找帘布收缩的影响因素，分析帘布收缩对钢丝帘布物料清单质量结构及钢丝帘线密度的影响，给出整经辊和压力辊沟槽间距的修正方法。结果表明，通过对整经辊和压力辊沟槽间距的修正及对生产过程的严格控制，可尽可能稳定和减小帘布幅宽收缩率，进而精确计算轮胎安全倍数和控制轮胎质量，避免材料浪费。 |
| 英文摘要: |
| Statistical analysis on the width shrinkage of calendered steel cord for all-steel radial tire was made to look for the influencing factors of the cord shrinkage rate，the influence of the cord shrinkage on the mass structure in steel cord bill of materials and the density of steel cord was analyzed，and the correction method of groove spacing between warping roller and pressure roller was given.The results showed that through the correction of the groove spacing between warping roll and pressure roll and the strict control of the production process，the width shrinkage rate of the cord could be stabilized and be reduced as much as possible，so as to accurately calculate the safety multiple of the tire，and control the tire mass，which could avoid material waste. |
