Beschreibung
Zusammenfassung:	An apparatus for coating graphite electrodes comprises a support having parallel horizontal guideways at one end of which is a fixed headstock whose spindle is coupled by gearing to a lead screw and is driven at a constant speed. At the other end of the guideways is a movable tailstock whose spindle is clamped by an electric motor and slip clutch against an electrode supported between the spindles. The lead screw drives a longitudinal slide which carries a plurality of cross-slides including a cleaning tool, a metal-depositing spray head, an arc-depositing head and a grinding device each on a respective cross-slide. The entire unit is enclosed in an acoustical housing having a lid which can be opened to permit lowering of the electrode into place and a door through which the operator can have access to the apparatus.
