Abstract
PURPOSE: To automatically provide strong raw yarn, such as, a tire cord, etc. with the optimum twirst, by twisting the raw yarn by fixed tension by using two chucks which faces each other.
CONSTITUTION: Yarn 8 drawn between a yarn guide chuck 16, which rotates near a lower bottom, through an upper auxiliary chuck 10' is admitted into chucks, closed and seized when the travelling direction of the yarn and the directions of the twist chucks of collars 40, 42 agree, the yarn 8 approaches to the chucks 40, 42 and the chucks are opened. A guide chuck 16" is opened according to a control program of an automatic tester, and an end of the yarn 8 is delivered to the twist chucks. The yarn is upward moved when tension is brought to fixed value by a slackness angle of rovolution or the length of a T arm because the chuck 40 is revolved, the chuck surfaces of the chucks 40, 42 are directed in the direction rectangular to the yarn, and the yarn is twisted by rolling and revolution in a plane crossing at right angles with the flowing of the yarn by friction with the fixed collar 40 when the chuck 42 is rotated by means of a pulse motor.
