The invention concerns a new method of, and apparatus for, drawing wire which uses a partial turn of wire wedged in an endless groove (32) in a rotating wheel (31) to generate the necessary drafting tension, the wire being cooled by direct contact with liquid coolant (38) as it leaves the sizing opening (36) and while it is wedged in the groove. …<??>In a multi-stage apparatus, the coolant would be removed from the wire downstream of the wheel and upstream of the next sizing opening (e.g. by an air wipe 39). |
