Patent ID: 7955487

Claim:
A device for electrolytically treating flat work pieces ( 1 ), said device comprising: a) at least two conveying paths (T′, T″) that run substantially parallel to each other for conveying the work pieces thereon, b) at least one assembly (A) that is disposed between the conveying paths and that comprises a first rotatable contacting electrode ( 2 ) and a second rotatable contacting electrode ( 8 ), with the first and second contacting electrodes ( 2 , 8 ) being associated with a respective one of the conveying paths where said electrodes ( 2 , 8 ) abut against the work pieces ( 1 ) while being spaced from the respective other conveying path, with c) the first and second contacting electrodes ( 2 , 8 ) comprising on the periphery thereof at least two segments ( 9 , 10 ) each, that are insulated against each other and are connected to a current source ( 5 ), with d) a first segment ( 10 ) of the first contacting electrode ( 2 ), which abuts against the work pieces ( 1 ) being conveyed on a first conveying path (T′), and a first segment ( 10 ) of the second contacting electrode ( 8 ), which abuts against the work pieces ( 1 ) being conveyed on a second conveying path (T″), said first segments ( 10 ) being connected to a first pole of the current source ( 5 ) and with e) a second segment ( 9 ) of the first contacting electrode ( 2 ), which is turned towards the work pieces ( 1 ) being conveyed on the second conveying path (T″) and is spaced from said second conveying path, and a second segment ( 9 ) of the second contacting electrode ( 8 ), which is turned towards the work pieces ( 1 ) being conveyed on the first conveying path (T′) and is spaced from said first conveying path (T′), said second segments ( 9 ) being connected to a second pole of the current source ( 5 ), so that electrolysis areas (E) for processing the work pieces ( 1 ) are formed between the second segments ( 9 ) of the first and second contacting electrodes ( 2 , 8 ) and the work pieces ( 1 ), a current flowing through said electrolysis areas (E), and f) the assembly (A) and the work pieces ( 1 ) being in contact with a treatment liquid.
