ABSTRACT:
For electrolytic treatment of electrically mutually insulated, electrically conductive structures4on surfaces of electrically insulating foil material (Fo), is unloaded from a store15′, 15″, transported on a conveying line through a treatment unit1and brought in contact with treatment fluid F1. During transportation, the material Fo is guided past at least one electrode arrangement, having at least one cathodically polarised electrode6and at least one anodically polarised electrode7, both being brought in contact with the treatment fluid F1and being connected to a current/voltage source8. Current flows through the electrodes6, 7and the electrically conductive structures4. The electrodes6, 7are screened from each other so that substantially no electric current is able to flow directly between oppositely polarised electrodes6, 7. The material Fo is finally loaded back onto a store15′, 15″.
