子午线轮胎内衬层生产简析

Processing technology of radial tire inner liner

介绍了子午线轮胎内衬层的两种生产方法———四辊压延法和辊筒机头挤出法，并简要分析了它们的优缺点。讨论了辊筒机头挤出法的工作原理和宽幅机头挤出胶片宽度的确定方法。认为辊筒机头挤出法的生产质量优于四辊压延法，但其设备投资远高于四辊压延法。

The two methods——four roll calender and roller die extruder methods for the radial tire inner liner are introduced and their benifits and shortcomings are briefly analysed.The principle of roller die extruder method and the determination of rubber sheet width on wide roller die extruder are discussed.It is considered that the quality of the product made by roller die extruder method is better than that by calender method,but the equipment expenditure of the former is much more than that of the latter.
