摘　　要：探讨全钢子午线轮胎胎里露线的检查方法和产生原因并提出预防措施,介绍两鼓成型机、三鼓成型机和轻型载重轮胎成型机平宽的测量方法。胎体帘线假定伸张值过大,容易产生胎里露线等缺陷;改造检查区域的灯光设置可以降低漏检率;选取合适的胎体帘线假定伸张值,确定成型机钢圈定位等关键控制点,提高生产工艺精度,降低生产缺陷和改进检测方法可以降低胎里露线缺陷率和漏检率。The inspection methods and causes of exposed cords in the inner surface of all-steel radial tire were analyzed and the corresponding corrective actions were proposed. The measurement methods of the width of bead to bead of the two-drum,three-drum and light truck tire building machine were discussed. It was found that when the presumed stretch ratio of carcass cord was too high,the defect rate of exposed cords in the inner surface increased. The missed detection rate could be reduced by changing light settings of the inspection area. The defect rate and missed detection rate of exposed cords in the inner surface could both be reduced by choosing appropriate presumed stretch ratio of carcass cords,setting up critical control points such as the bead wire positioning of building machine,improving process accuracy,reducing production defects and improving test method.
