Abstract
A method of reducing the cross-sectional area of one or more extruded wires as a combined effect of drawing and rolling, by passing the wires through reduction rollers driven at a peripheral speed which exceeds the greatest extrusion speed of any of the wires, thereby avoiding the formation of fins due to the passage of excess material between the rollers. Use of this method makes it unnecessary to track the rotation speed of the rollers with variations in the extrusion speeds.
