Abstract
A double twist spindle apparatus is arranged to wind two lines of first-twisted component yarns after arranging them in order and performing second twisting operation. A take-up bobbin which winds the first-twisted component yarns is rotated by skin frictional drive of a driving roller wherein a yarn winding speed is kept constant even if winding diameter is increased. A hollow spindle and a driving roller are independently driven by separate driving sources. Accordingly, the relation between rotating speed of the hollow spindle and winding speed of the take-up bobbin can be simply changed by regulating the rotational ratio of the two driving sources.
