ABSTRACT:
Electrolytically deposited copper is stripped from a cathode by first flexing the cathode to cause at least part of the copper deposit to separate from the cathode, and then wedge-stripping or gas-blasting the remainder of the copper from the cathode. Perferably the cathode is a stainless steel sheet, and flexing is achieved by means of hydraulic arms which press the center of the sheet first in one direction and then in the opposite direction. The cathode is supported along its bottom edge and held upright during the process.
