METHOD FOR APPLYING A PROTECTIVE STRIP TO A CATHODE SHEET FOR ELECTROLYTICALLY OBTAINING A METAL FROM A ELECTROLYTIC FLUID

摘要

The invention relates to a method for applying a protective strip (3) to a cathode sheet (1) for electrolytically obtaining a metal from a electrolytic fluid. The plastic protective strip presses onto the warmed cathode sheet with the aid of a pressing tool (4), said cathode sheet being arranged below a melt of the surface thereof facing the cathode sheet and is subsequently cooled over the cathode sheet. The protective strip is applied to an elastically flexible pressing tool, which is pre-curved counter to the cathode sheet, in the direction of pressing in order to ensure a tight fitting thereof, and is pressed, in an outwardly progressive manner, onto the cathode sheet by the curving of the pressing tool in a defined positioning area.
