<p>PURPOSE: To eliminate a covering, while retaining coating rubbish on a copper wire and a surface state to be uniform and clean, when eliminating the coating of both edge parts of a coating copper wire as a pre-treatment of, for example, a deflection yoke manufacturing machine. CONSTITUTION: A coating copper wire F is supplied, while an upper can body 10 and a lower can body 1 are open. When a site where the coating should be removed arrives at a position M, the upper can body 10 is lowered, and an airtight chamber A and an electrolyte chamber O are formed. An electrolyte is poured to a water level that is higher than the coating copper wire F in the electrolyte chamber O, and a high-pressure air is supplied to the adjacent airtight chamber A, thus preventing the electrolyte from leaking. Then, a voltage is applied so that a discharge (electrolytic spark) for eliminating the coating of the coating copper wire F can be generated in the electrolyte, and the coating is eliminated in the liquid After that, a certain amount of electrolyte is delivered, the upper can body 10 is opened, and a certain amount of coating copper wire F is fed downstream, and then similar processes are repeated.</p> |
