    • An apparatus for anodizing a support for a lithographic printing plate which comprises a backing roller which guides a web made of aluminum or an alloy thereof in a state of contacting the backing roller, (an) electrode(s) which is/are arranged along the peripheral surface of the backing roller in a concentric arc, an electric supplier which is provided at least on the upstream side or the downstream side of the backing roller, and an electrolyte solution which fills the clearance between the backing roller and the electrode, and an anodizing method using the same. By using the apparatus, the electric voltage loss can be reduced in electrolyte solution, and only a single surface of the supports is anodized without the necessity for providing any special means. Anodizing can be conducted at a high speed and the thickness of anodized layer easily increased. Moreover, thin supports can be anodized without fusion troubles.
    • 一种阳极氧化用于平版印刷版的支撑体的装置,其包括在与所述背衬辊接触的状态下引导由铝或其合金制成的网的背衬辊,(a)沿着 背衬辊的圆周表面为同心圆弧,至少设置在背衬辊的上游侧或下游侧的供电器以及填充支承辊和电极之间的间隙的电解质溶液,以及 阳极氧化法使用它。 通过使用该装置,可以在电解液中降低电压损失,仅仅支撑体的单个表面被阳极氧化,而不需要提供任何特殊的手段。 阳极氧化可以高速进行,阳极氧化层的厚度容易增加。 此外,薄支撑件可以被阳极氧化而没有融合问题。

    • An electrolytic treatment apparatus for continuously electrolyzing an elongated product of aluminum or an aluminum alloy at a low electrolyzing voltage and reduced amount of electric power. The apparatus includes at least one electrolytic section and front- and rear-side power supply section disposed respectively at front and rear sides of the electrolytic section in the longitudinal direction of the elongated product in the electrolytic section. Each of the power supply sections contains at least one electrode, and the electrolytic section contains a plurality of electrodes. The electrolytic section and the power supply sections are filled with an electrolyte in which the elongated product and the electrodes is immersed. A plurality of power sources are provided, with an electrode of the electrolytic section at a front-side portion thereof being connected to an electrode of the front-side power supply section through one of the power sources, and another electrode of the electrolytic section at a rear-side portion thereof being connected to an electrode of the rear-side power supply section through another of the power sources. The invention also provides an electrolytic treatment method by which the above apparatus is operated.
