Abstract
Drafting system for textile yarns and including a driven feed roll, a driven output roll, a low friction freely rotatable heated roll located between the driven feed roll and the driven output roll and operating at essentially the same surface speed as the driven feed roll, the freely rotatable heated roll being driven by engagement with the yarn and whereby sufficient yarn tension automatically is transferred upstream of the freely rotatable heated roll to pretension the yarn before it contacts the freely rotatable heated roll with drafting taking place near the location where the yarn leaves the freely rotatable heated roll to pass toward the driven output roll.
