    • Described is a process for producing a self-supporting metal foil (40), in particular copper foil, which by virtue of its constitution has a low shearing strength and which can be structured in a sharp-edged configuration. In this case a base layer of the metal foil (40) is galvanically deposited on a roller cathode (22). A cauliflower structure (60) comprising the metal is deposited in firmly adhering relationship on the metal base layer (58) by means of an additional anode (32) provided between the roller cathode (22) and the anode cage (24). The metal foil (40) comprising the metal base layer (58) and the cauliflower structure (60) is detached from the roller cathode (22), rinsed and dried. The dried foil (40) comprising the metal base layer (58) provided with the cauliflower structure (60) is moved through a black oxide bath (46). There then follows a rinsing operation and a drying operation.
    • 描述了一种用于生产自支撑金属箔( 40 >)的方法,特别是铜箔,其由于其构造具有低剪切强度并且可以被结构化 在一个尖锐的配置。 在这种情况下,将金属箔的基层( 40 )电镀沉积在辊阴极( 22 PDAT>)上。 包含金属的花椰菜结构( 60 )通过牢固粘附的关系沉积在金属基底层上( 58 设置在辊阴极( 22 )之间的阳极( 32 )和阳极笼( 24 )。 包括金属基层( 58 )和花椰菜结构( )的金属箔( 40 > 60 )从滚筒阴极( 22 )分离,冲洗干燥。 包括具有花椰菜结构( )的包含金属基层( 58 PDAT>)的干燥箔( 40 PDAT> 60 )移动通过黑色氧化物浴( 46 )。 然后进行漂洗操作和干燥操作
