Abstract
Method and apparatus for drawing wire which uses a partial turn of wire wedged in an endless groove in a rotating wheel to generate the necessary drafting tension and wherein the drawn wire is cooled by direct contact with a liquid coolant as it leaves the die and while it is wedged in the groove. In a multi-stage apparatus, the coolant is removed from the wire downstream of the wheel and upstream of the next sizing opening by an air wipe.
