An apparatus for applying a coating material to a substrate such as a razor blade, comprising a drum unit having a plurality of driven hub assemblies, each of which supports carrier means for carrying a large number of razor blades, and in which the hubs are driven, for example, by an epicyclic gear or chain mechanism, so as to expose the desired portions of the carriers, in a desired timed relation, to a coating material which is caused to emanate from a fixed source. The source comprises a so-called sputtering module including housing having, at the top part thereof, a pair of angled target plates from which the coating material is taken, and, at the bottom thereof, an opening past which the carriers are moved by the drum.
