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

摘要

A method is described for applying a protective strip onto a cathode plate for obtaining a metal in an electrolytic manner from an electrolytic fluid, with the protective strip made of plastic being pressed by means of a pressing tool against the heated cathode plate by melting on its surface facing the cathode plate and thereafter being cooled through the cathode plate. In order to ensure a snug fit of the protective strip, it is applied onto a pressing tool which is elastically resilient in respect of pressing and bulges forwardly against the cathode plate and is pressed against the cathode plate in a progressive manner starting from a contact section determined by the bulging of the pressing tool.
