摘　　要：为了实现国产粗纱机的精密定长,分析了无精密定长国产粗纱机落纱长度不一致产生的原因,并针对性的采取其实现精密定长落纱的措施。认为,粗纱张力、假捻器、锭翼清洁、温湿度等是影响粗纱定长的主要因素;三种粗纱长度之间的差异可通过技术改进和管理措施来改善。生产实践证明:通过相关措施的实施,粗纱落纱长度与工艺设定长度差可控制在±1m,可有效地改善重量不匀率及降低回花率。To realize domestic roving machine precision fixed-length, reasons of domestic roving machine without precision fixed-length doffer length disaccord were analyzed, measures of realizing precision fixed-length doffer were adopted accordingly. It is considered that main factors of effecting roving fixed length should be roving tension, false-twister, flyer cleaning, temperature ＆ humidity et al. Differences among three roving lengths can be improved technology mod-ification and management. Practice proves that through implementing related measures,difference between roving doffer length and processing setting length can be controlled in ±1m, weight unevenness and cotton waste percentage can be improved effectively.
