Spindle top
摘要:
An improved spindle top having between 3 and 8 fingers together in association with yarn-catching, yarn-directing grooves provides advantages in the manufacture of spun yarns. The improved top reduces ends down by reducing tension upstream of the spindle top, and the improved top is also believed to reduce the amplitude of tension surges which occur as the yarn rolls from one catch point on the spindle top to another.
