Abstract: Disclosed is a spindle blade for a false twist spindle characterized by a unitary element blade and a twist trapping pin that is mounted on one end of the spindle blade. The pin is located within the bore in the blade and the wall of the tube is characterized by the absence of any apertures therethrough. The blade is able to withstand rotational forces generated by a very high speed of rotation. Due to the enclosed position of the pin it is necessary to provide a method for threading the false twist spindle and such a method is also disclosed.
