摘要：为了改造旧摇架、优选新摇架，提高成纱质量，介绍细纱摇架满足质量的技术要求，对比不同制造企业不同类型摇架的性能，在FA506型细纱机平面牵伸和V型牵伸技改过程中设计不同方案、不同纺纱品种进行试纺；对比试纺指标并分析旧摇架使用压力棒存在的工艺问题。指出：推广试用新型专件器材需考虑设备对纱线作用过程中的各力平衡,确保生产稳定；摇架对牵伸区纤维的控制效果影响极大，优选摇架时应跟踪试纺结果并兼顾生产环境、品种和工艺条件。

Abstract:In order to reform the old cradle,optimize the new cradle and improve the yarn quality,introduction is made to the technical requirements of spinning cradle to meet the quality,the performance of different types of cradle which are made in different manufacturing enterprises are compared.Different schemes and spinning varieties for trial spinning are designed to optimize plane draft and V draft of spinning frame FA506,and the trial spinning indexes are compared.Analysis is done to the process problems of using the pressure bar on the old cradle.It is pointed out that the balance of forces in the process of the action of the equipment on the yarn should be considered in the promotion and trial use of new accessories and special parts,which can ensure stable production.The cradle has a great influence on the control effect of fiber in the draft area.The results of trial spinning should be followed and the production environment,varieties and process conditions should be taken into account when optimizing the spinning cradle.
