ABSTRACT:
The invention relates to a new spindle for false twist by friction.
This spindle contains two hollow elements with parallel axes, rotating in opposite directions, equipped at their ends with friction elements, and it is characterized by the fact that it also contains at least one member for guidance and return of the thread positioned between the rotary hollow cylindrical elements, and which does not stop the twist imparted to the thread by the friction elements, the axis of this guidance and return member being offset with respect to a plane containing the longitudinal axes of the hollow cylindrical elements, and the plane in which the thread is contained as it passes around the guidance and return member intersecting the plane formed by the longitudinal axes of the hollow cylindrical elements.
This spindle is particularly applicable in the high-speed false-twist texturing of synthetic threads.
