1. Apparatus for electrolytic semi-continuous deposition of a metal on a weakly conductive, flexible substrate characterized in that it comprises an electrolytic cell having a first and second planar electrodes placed in said electrolytic cell and a t least one element forming a mask placed between and spaced from the two electrodes where the substrate is placed between one of the electrodes and the mask, said mask is rigid and made from an electrically insulating material having at least one opening with the shape of the deposit which it is to produce on said substrate and is provided with motor means permitting the displacement thereof in a direction normal to plan of the substrate between a first position where it is remote from the substrate to be treated and a second position where it is engaged on said substrate.
