探讨FA387型并条机的技术性能和应用效果.阐述了FA387型并条机技术规格、性能特点及操作使用方法,并与FA316B型并条机进行了纺纱对比试验.结果表明:FA387型并条机在纺纱质量和牵伸同步性能方面优于FA316B型并条机.认为:运用伺服电机及数字化闭环控制技术,实现主牵伸无级调节和动态监控的高速并条机,具有工艺调整便捷、机构简化、维护方便、改善纺纱质量、提高生产效率、减少用工的特点,代表了高速并条机技术的新趋势.%Technical performance and application effect of FA387 drawing frame were discussed. Technical specifications , performance characteristics and operating use of FA387 drawing frame were introduced, the spinning test was contrasted with FA316B drawing frame. The result shows that FA387 drawing frame is better than that of FA316B drawing frame in aspects of spinning quality and drafting synchronization performance. It is considered that servo motor and digital closed-loop control technology are applied by high-speed drawing frame, the main drafting stepless adjustment and dynamic monitoring can be realized. Performance of this kinds of drawing frame are better, such as convenient process adjustment, simplified structure, easy maintenance, better yarn quality, higher efficiency and less labor. New trend of high-speed drawing machine technology can be represented.
