Abstract:
Apparatus for accomplishing continuous electrolytic precipitative deposition processes, said apparatus comprising:(a) a rotating cathodic live cylinder having opposite axial ends and a surface of a width extending between said opposite axial ends and being electrically conductive entirely over said width of said surface;(b) at least one anode disposed approximately concentrically with and radially outwardly from said surface of said live cylinder so as to define a spacing volume therebetween in which flows an electrolyte having in a dissolved form a metal to be deposited; and(c) a pair of shielding strips each comprised of an electrically insulating material and having opposite inner and outer portions, said shielding strips being spaced apart from one another and at said inner portions thereof being disposed in said spacing volume between said anode and said surface of said live cylinder and extending along opposite margin regions on said surface of said live cylinder respectively located adjacent to and contiguous with said opposite axial ends of said live cylinder so as to define a usable region on said surface of said live cylinder extending between said opposite margin regions thereof and oppositely bordered by said shielding strips such that said usable region is electrically exposed to said anode and thus available to be utilized during an electrolytic precipitative deposition process, said shielding strips at said inner portions thereof also entirely overlying said opposite margin regions on said surface of said live cylinder such that said opposite margin regions are entirely electrically shielded from said anode by said shielding strips and thus said opposite margin regions are not available to be utilized during the electrolytic precipitative deposition process so as to prevent a deposit of a coating of the dissolved metal of the electrolyte on said opposite margin regions of said surface of said live cylinder, said shielding strips further being disposed so as to encompass said opposite margin regions on said surface of said live cylinder coextensively with where the electrolyte fills said spacing volume, said shielding strips at said outer portions thereof extending in opposite directions from said spacing volume to beyond said anode and said opposite axial ends of said live cylinder.
