Abstract
The purpose of this study is to devise a practical method to reduce tension variation on the ring spinning frame by measuring spinning tension.
The results of the study are summarized as follows:
(1) The variable speed drive of spindles is useful for reducing the tension variation for chases in which the winding angle varies during the vertical motion of the ring rail. It is possible to keep tension uniform if the speed of the spindle is properly adjusted with consideration given to the balloon height and the winding angle, and if the balloon-control ring is fixed.
(2) The smaller the winding angle, the larger the spinning tension. A winding angle smaller than 23 degrees is undesirable.
(3) Use of the antinode ring reduces the spinning tension level by an average of 15% and the variation in the spinning tension by 50%. The position of the control ring should be at 40-50% from the bottom of the balloon. A control ring of equal radius with the spinning ring can be used with satisfactory results.
(4) The variation in spinning tension can be reduced by proper vertical motion.
