ABSTRACT:
A false twisting method and device for twisting a yarn which runs under a predetermined tension includes an arrangement wherein the yarn is wound about a member such as a cylindrical member positioned approximately at the halfway point of the running of the yarn, and a yarn downstream of the wound member and a yarn upstream of the wound member intersect each other in a contacted state to provide a twist in the yarn.
