Abstract
A threading device comprises a star wheel formed of two half sections secured together and rotatably mounted in a casing to project therefrom. The confronting surfaces of the radial projections of the mating star wheel parts near the tip thereof are formed with arcuate grooves in which an arcuate central portion of a rod-like threading member is slidably located but trapped therebetween. The threading member has elongate end portions projecting one on each side of the star wheel and one such portion is adapted for connection thereto of a flexible elongate line to be threaded by the device. The leading elongate end portion of the threading member is passed through, or beneath, an element with which the line is to be threaded to effect a threading operation.
