Title: Threading device and method for false twist tubes

Abstract: A threading tool for a quiet-running false-twist spindle of the type having a twist pin across the bore and no conventional threading slots or holes. The tool consists of a length of fine-gauge wire with an end for grasping and a second end having two hook-shaped bends in planes preferably substantially perpendicular to each other. Yarn is threaded quickly around the pin with six simple vertical and rotational motions of the tool. Mirror-image versions of the tool provide for S- or Z-twist as desired. The tool makes it practical to eliminate the whistling noise produced by high-speed spindles having threading slots or holes.
