摘　　要：为提高传统细纱机牵伸结构效能,分析了现有三罗拉双胶圈牵伸系统存在的问题,并进行了技术改进,获得了较好效果。认为:可通过采用RS-6939S型上销、加大下胶圈对中罗拉的包角,采用特殊的内花纹下胶圈,优化设计胶圈宽度,改进现有的新型下销结构等技术措施,达到进一步提高牵伸效能、改善成纱质量、节约原材料、降低能耗的目的。To improve traditional draft system effect in spinning frame, problems in three-roller double apron draft system were analyzed, related technology modification was done and better effect can be got. It is considered that through selecting a series of measures such as adopting RS-6939S type top pin, increasing down apron covering angle to middle roller, adopting special interior pattern down apron, optimizing apron width, modifying existing new type down pin structure, draft effect can be improved further, yarn quality can be improved, raw material can be saved and energy consumption can be reduced.
