Apparatus for cooling the wire in a wire drawing machine, particularly by cooling one or more of the drums around which the wire is wrapped. A drum around which the wire is wrapped, either a pulling drum or a storage drum, is made hollow and filled with a first fluid cooling medium. A liquid conductive heat exchanger is placed within said first cooling medium within said drum and extends through suitable means outwardly therefrom. A second cooling medium is caused to flow through said heat exchanger for extracting heat from said first cooling medium. Thus heated wire from a drawing die is wrapped around said drum, yields at least a substantial portion of its heat to said drum which heat is then absorbed by the first cooling medium and extracted therefrom and carried to suitable disposable means by the second cooling medium. |
