Abstract Low Friction Drafting System for Yarns Low friction draftling system (54) for yarn (56) and having in sequence a driven feed roll (58), low friction first freely rotatable hot roll (66) for preheating the yarn, a low friction second freely rotatable hot roll (70) far thermally stabilizing the yarn, a driven output roll (74), with tension automatically transferring upstream of the preheater roll (66) to preheat the yarn and with the two heated rolls (66,70) being driven by engagement with the yarn; the thermally stabilizing roll (70) operates at a greeter speed than the preheater roll (66) and drafting of the yarn occurs between the two freely rotatable hot rolls (66,70).
