Description
На фиг, 1 и 2 представлена схема устройства дл осуществлени предлагаемого способа.Figs. 1 and 2 show a diagram of an apparatus for carrying out the proposed method.
Ленту 1 пропускают через электролитическую ванну 2 с раствором, разделенную перегородками 3 на катодные JI анодные зоны, в которых установлен плоские электроды 4 и 5.Tape 1 is passed through an electrolytic bath 2 with a solution divided by partitions 3 into cathode JI anode zones in which flat electrodes 4 and 5 are installed.
Сначала дл обрабатываемой ленты йо указанной формуле рассчитывают угол перегиба с учетом материала и размеров ленты, а также состава примен емого раствора. Ленту заправл ют через стойки 6, передвигаемые вдоль паза направл ющих 7 и, закрепл их, задают ей угол перегиба с помощью ст жек 8, Затем на электроды подают электрический ток и осуществл ют npo цесс бипол рного электрохимического полировани , перемеща ленту по траектории , симметричной относительно середины длины чейки.First, for the tape to be treated with the indicated formula, an inflection angle is calculated taking into account the material and the size of the tape, as well as the composition of the solution used. The tape is filled through the pillars 6, moved along the groove of the guides 7 and, having secured them, set the angle of inflection with the help of the tie pins 8. Then electric current is applied to the electrodes and the process of bipolar electrochemical polishing is carried out, moving the tape along the path symmetrical relative to the middle of the length of the cell.
Плотность тока ка поверхности лен ты замер ют, например, в п ти равномерно расположенных -по длине зоныThe current density on the surface of the tape is measured, for example, in five equally spaced along the length of the zone.

Как видно из таблицы,плотность тока по длине обрабатываемой ленты распредел етс равномерно.As can be seen from the table, the current density along the length of the tape being processed is evenly distributed.
Таким образом, изобретение позвол ет выравнивать плотность тока по всей длине обрабатываемой ленты,вследствие чего исключаетс брак по разнотолщинности микроленты. Кроме того, расшир етс номенклатура обрабатываемых лент с применением одних и тех ж электродов.Thus, the invention makes it possible to equalize the current density along the entire length of the tape being processed, as a result of which the discarding of micro-tape irregularities is eliminated. In addition, the nomenclature of the tapes being processed is expanded using the same electrodes.
