METHOD AND ARRANGEMENT FOR COLLECTING SAMPLES OF CATHODE METAL DEPOSIT SHEETS

摘要

The invention relates to a method and to an arrangement for collecting cathode samples (1) of cathode metal deposit sheets (2) formed on a mother plate (3) of permanent cathodes (4) in an electrolytic cell (7). A permanent cathode tracking system being configured to in response to reading an unique remotely readable identifier (5) of the cathode metal deposit sheet carrying permanent cathode (6) at a stripping station (8) to retrieve permanent cathode location information from a memory unit (16) and to transmit the permanent cathode location information to a sampling station (14). The sampling station (14) comprises a printer (21) configured to print the permanent cathode location information on a label (18) and configured to provide the cathode sample (1) with the label (18).
