| Abstract: | The controlled negative let-off motions are widely adopted in modern needle looms. The motions are simple in construction and flexible in setting-up, and besides, able to some extent to adjust the warp tension automaticaly. Based on the analysis of the dynamic properties of the motions according to the principles of automatic control, the article has revealed the mechanism of automatic tension adjustment and discussed the effect of the interference and technical factors on the dynamic properties. The static properties of the motions have been analysed as well in the article, which are highly instructive to the technical setting-ups in needle looms. |
