Abstract
The deflecting element is positioned adajcent to a main heater in order to deflect the thread for two passes in the heater. The deflecting element includes a cylindrical surface which is disposed at an angle to the axis of rotation of the element as well as pair of flanges which define the cylindrical surface. A false twist device is located downstream of the heater to impart a false twist in the thread. The false twist is able to propagate through the thread from the false twist device to the heater and deflecting element back to the supply rolls.
