Numbering device for typographic numbering

A numbering device for carrying out numbering in sheet-fed or web-fed numbering presses, the numbering device comprising a casing and 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, the numbering device further comprising electro-mechanical actuation means for setting the position of the numbering wheels,

• wherein the electro-mechanical actuation means are disposed in an inner space of the casing of the numbering device and are mechanically autonomous, the electro-mechanical actuation means comprising a plurality of independent driving means for actuating a corresponding plurality of the numbering wheels,
• wherein the independent driving means are distributed within an angular sector about the rotation axis of the numbering wheels and are located at equal distance to the rotation axis of the numbering wheels,
• wherein each independent driving means at least comprises an electric motor driving an associated numbering wheel through a gear-wheel assembly,
• wherein the gear-wheel assembly comprises a driving pinion mounted onto a shaft, which driving pinion meshes with a toothed wheel disposed on a side of the associated numbering wheel, and wherein the driving pinion is configured to be adjustable in an axial direction along the shaft, and
• wherein the driving pinion is equipped with a releasable clamping ring for adjustment of the axial position of the driving pinion along the shaft.
