Abstract
A yarn is twist-drawn on an apparatus employing a 2-for-1 twist spindle; at least one guide roll positioned above the spindle; means suitable for receiving a yarn from said guide roll and drawing the yarn; and means suitable for winding the drawn yarn, wherein the guide roll comprises a cylindrical surface mounted on a shaft which is attached to a base suitable for positioning the cylindrical surface so that the yarn rides on the surface of the roll in a relatively fixed position and a substantial amount of twist is not trapped in the yarn ahead of the guide roll.
