A method and apparatus for stripping electro-deposited metal sheets from a cathode blank. The blank has opposite faces, upstream and downstream ends. At least one sheet is provided on at least one blank face to define upstream and downstream edges. The apparatus comprises a stripping assembly for stripping the electro-deposited metal sheets from the cathode blank, a discharge assembly and a metal sheet out-feed assembly. The discharge assembly is positioned downstream of the stripping assembly and includes opposite guide rollers adapted to engage the metal sheet exiting the stripping assembly. The metal sheet out-feed assembly is positioned downstream the discharge assembly for receiving the metal sheet. When the metal sheet has been stripped from the cathode blank, the guide rollers controllably feed the metal sheet to the out-feed assembly. The method comprises stripping the metal sheets from the cathode and controllably discharging the stripped sheets to an out-feed assembly.

Method and apparatus for stripping electrodeposited metal sheets from permanent cathodes

The present invention provides a linear conveyer assembly for cathode plates comprising a continuous timing belt provided with cathode plate conveying assemblies attached thereto and having cam rollers running in a pair of channels running along either side of and parallel to a forward path of the belt. The conveying assemblies insure that the cathode plate conveying assemblies are aligned in an overhead position in such a way that the cathode plates move in a direction substantially perpendicular to a surface thereof. The timing belt is fabricated from a corrosive resistant material and allows an accurate positioning of the cathode plates due to a non-permanent stretch character thereof.
