Abstract:

Results of simulation investigations of the influence of changes in the spinning zone geometry of a ring spinning machine on the tension and quality of the yarn manufactured are presented in this study. Changes in the geometry resulted from modification of the conventional drafting system into a compact drafting system. For the investigations, construction parameters of the machine and the technological process of spinning were taken into consideration. Numerical investigations were based on the mathematical model for the dynamics of yarn motion through the twisting-winding unit. Experimental tests were performed on the Polish ring spinning machine type PJ 35, equipped with a conventional drafting system and the author’s compact drafting system. It was shown that changes in the spinning zone geometry on the spinning machine caused by modification of the conventional drafting system into a compact system had no effect on the mean tension value of the yarn. Instead it diminished the amplitude of tension during the revolution around the spindle.
