PURPOSE:To make it possible to carry out electrolytic treatment stably by dividing a cathode which touches a material to be treated into a large number of collector rollers against one anode and controlling the current of electricity supplied to these rollers individually. CONSTITUTION:After a stripe negative plate 1 is pretreated properly, a quantity of electricity within an allowable limit is applied to collector rollers (a), which are cathodes shown as A, B, C, and installed separately. The collector rollers (a) of A, B, C and an anode (b) make a pair and cathodes D, E, F and an anode (b) make another pair. Terminals in the + side form common anodes (b) to all the paired cathodes and values of current to be supplied to the rollers (a) are controlled separately. With this structure, current multiplied by the number of the collector rollers can be applied and the current is controlled separately, so that productivity can be improved. |
