Beschreibung
Zusammenfassung:	Fully automated apparatus for coating graphite electrodes to be used in electric arc steel making processes, comprises a support device (1) having two sets of parallel guide surfaces along its length. On the first set of guide surfaces slides a plate (14, 7) carrying tools (8 to 13) for effecting the coating, and on the second set of guide surfaces slide two carriers (4) bearing contact clamps (6). An electrode support plate (20) is disposed between the carriers. The tool-carrying plate and the contact clamps are driven by an electric motor (26) to which they are connected by a reduction gear (3). An electrode to be coated (25) is deposited on the support plate (20) from a transporting arrangement (22) included in the apparatus, and is then taken up by the contact clamps (6). After being coated, the electrode (17) is returned to the transporting arrangement (22) and taken away. The electrode may be preheated by burners 23; it may rotate during coating, and tools 13 to 8 respectively are a roughener, a metal spray gun, an alloy applicator, a non-metal applicator, e.g. for graphite, an electric arc device, and a polisher.
