In order to promote the technical progress of covered spindle and covered yarn,the de-velopment status of covered spindle in China is analyzed from manufacturing end of covered spindle,the main raw material spandex of covered yarn,and so on.Technical development trends and design ideas of covered spindle are discussed from the aspects of large package bob-bin,energy saving and electric spindle,unconventional design ideas,and so on.It is pointed out that the covered spindle will continue to grow steadily and should meet the requirements of heavy load and high speed at the same time.The electrical spindle has the characteristics of high production efficiency,energy saving,low noise,and is suitable for many varieties and small bat-ches,and so on.Both the integration design and the split design of motor and spindle need the joint participation and technical coordination of the main engine manufacturing enterprises,and the important technical indexes of spindles should be monitored and alarmed in real time,which can be automatically adjusted by the main engine controller.
