ABSTRACT:
The magnet carrier assembly of an electrographic copying device is fabricated from a number of separate parts instead of being machined from a single block of metal. The assembly can consist of a tubular body which supports the magnets either on the outside, or inside, peripheral surface. The tubular body can be formed by extrusion integrally with a radial spider connected to a hub which supports the body. In another form the carrier can be built up by combining specially profiled sheet metal strips with other axially extending elements with which they are joined in a tongue-in-groove arrangement.
