There is described a numbering device (1) for carrying out numbering in sheet-fed or web-fed numbering presses, the numbering device (1) comprising a numbering unit (6) with rotatable numbering wheels (7) carrying alpha-numerical symbols thereon, which numbering wheels (7) are disposed next to each other and rotate about a common rotation axis (17), the numbering device further comprising electro-mechanical actuation means for setting the position of said numbering wheels (7). The electro-mechanical actuation means are mechanically autonomous and comprise a plurality of independent driving means (15, 18-23; 23*) for actuating a corresponding plurality of said numbering wheels (7), which independent driving means (15, 18-23, 23*) are distributed about the rotation axis of the numbering wheels (7) in the form of a semi-circular arrangement and are located at equal distance to the rotation axis of said numbering wheels (7). |
