Abstract
A cathode head assembly is provided for holding a matrix during electroforming of a replica on the surface of the matrix. The cathode head assembly has a support member with an outer diameter at least as large as the matrix to be replicated; a compressable seal member positioned about the outer diameter of the support member; an outer ring member having means for engaging the seal member and having an inside diameter slightly larger than the outer diameter of the support member and a means for locking the outer ring in a position when the seal is held against the outer ring in compressed sealing engagement with a matrix mounted on the support member.
