Abstract
A cylindrically shaped hollow mandrel is disclosed which is suitable in an electroforming process used for the production of an endless seamless nickel xerographic belt. The mandrel set forth comprises a metal core member with a thin removable metal sleeve having a thickness between about 10 and 60 mils which is fitted over said core member to provide a surface for electroforming of the nickel belt. Mandrels disclosed in the present invention have the advantage of a longer lifetime of use in a continuous electroforming process because of the replaceable nature of the metal sleeve.
