Abstract: A device for nippling active electrode sections onto a combination electrode permanent upper section employing screw nipples to form the connection comprising an outer, essentially hollow cylindrical element and an inner hollow cylindrical element co-axially with in said outer element. The inner element is configured to couple with the connector element arranged on the upper end of the permanent section of said combination electrode. A drive is provided by means of which the inner element is rotatable in relation to the outer element around its axis.

Abstract: A device for the mechanical nippling up of electrode sections on an electrode positioned vertically in an electrode holder in an electric furnace, especially an arc furnace, by means of screw nipples forming the connection. The device comprises coaxial cylinders forming a coupling which can be coupled automatically or by control means with a connector element located on the upper end of the electrode section to be nippled up.
