本文介绍美国冶炼公司雷铜矿在雨天条件下胶带输送机胶带打滑和跑偏给生产造成种种困难的情况，增加配重防止打滑和采取种种纠偏措施均未见成效。引用国民胶带服务公司（NBS）研制的Flex－Lag高铝矾土陶瓷片压入橡胶衬面沟槽中形成的陶瓷衬面滚筒，取代原用的槽形橡胶村面滚筒解决了上述问题。
This article describes the difficulties caused by slippage and deviation of the tape conveyor belt during rainy weather at the U.S. mine smelter, and shows that it has failed to increase the counterweight to prevent slippage and take various corrective measures. The above problems are solved by referring to the Flex-Lag bauxite ceramic plate developed by National Adhesive Tape Service Company (NBS) into the ceramic lining roller formed in the groove of the rubber lining instead of the original grooved rubber village roller.
