摘　　要：探讨国产粗纱机落纱精确控制定长的方法。分析了影响粗纱落纱长度不一致的原因,通过制定输入窗口设定参数操作法和电气方式定层落纱操作等技术措施,可使落纱长度差异控制在2.0m以内。采取粗纱伸长率、各工序断头的控制措施,优化高效能假捻器以及设备运转的精细化管理工作,是减少粗纱工艺设计长度与粗纱落纱、退绕实际长度差异的有效方法。Method of domestic roving machine precise controlling doffing fixed length was discussed. The reasons for inconsistent length of the roving doffing were analyzed. By setting the input window parameter opera tion and electrical method fixed layer doffing operation and other technology measures, the difference of doffing length can be controlled within 2.0 m. High efficiency false twister and refined management of equipment opera tion were optimized by adopting control measures of roving elongation and breakages in each process. It was an effective method to reduce the difference between the design length of roving process and the actual doffing and un winding length of roving.
