Numbering device for typographic numbering

A numbering device for carrying out numbering in sheet-fed or web-fed numbering presses, said numbering device comprising a numbering unit with rotatable numbering wheels carrying alpha-numerical symbols thereon, which numbering wheels are disposed next to each other and rotate about a common rotation axis, said numbering device further comprising electro-mechanical actuation means for setting the position of said numbering wheels,

• wherein said electro-mechanical actuation means are entirely located within an inner space of a casing of said numbering device and are mechanically autonomous, said electro-mechanical actuation means comprising a plurality of independent driving means for actuating a corresponding plurality of said numbering wheels,
• wherein the numbering device further comprises calibration means for calibrating the position of the numbering wheels about the rotation axis, which calibration means include calibration sensors carried by at least one supporting member,
• wherein the supporting member is located in an upper part of the numbering device and extends parallel to the rotation axis of the numbering wheels, next to and along a side portion of the numbering unit so that each calibration sensor faces a corresponding one of the numbering wheels to be calibrated, and
• wherein the supporting member is rotatable away from the numbering unit.
