Abstract

The embossing machine incorporates at least one wheel (7) rotarily mounted on a pivot axle (8), connected to a drive mechanism, and fitted with hob-milling segments (11). At least one abutment element (14) has at least one hob-milling segment and has an active length just large enough to extend the hob-milling segment of the wheel to a complete periphery of the round object (1). A positioning piece (26) holds the round objects and is positioned between the wheel and the abutment element.
