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 each independent driving means comprises an electric motor driving an associated numbering wheel through a gear-wheel assembly, which gear-wheel assembly exhibits a reduction factor,
• wherein each electric motor is a brush-less DC motor with electronic commutation,
• wherein each independent driving means exhibits an overall reduction factor between an output of the electric motor and the associated numbering wheel,
• wherein the numbering device comprises more than six rotatable numbering wheels actuated by a corresponding number of the independent driving means,
• wherein a part of the numbering wheels are actuated by independent driving means and a remaining part of the numbering wheels are manually-actuated numbering wheels, and
• 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.
