Zusammenfassung:	An electroplated combing roller for use in a spinning unit of an open end spinning machine comprises an aluminum alloy cylindrical body, and a steel wire fixedly mounted in the cylindrical body. A hardened chromium plating is carried out after mounting the steel wire onto the aluminum alloy cylindrical body and the dimensions of the steel wire and aluminum alloy cylinder are interrelated in a manner such that only the exposed surface of the steel wire is plated with the hardened chromium while the exposed surface of the aluminum alloy cylinder is not so plated.
