Abstract
A numbering device for an offset printing press including a slide mechanism. The slide mechanism includes a pair of slide plates fixed to frames of the numbering device and two pairs of rollers fixed to frames of the main machine, wherein the slide plates are received between respective pairs of the guide rollers such that the numbering device can be slid towards and away from the main machine. A first gear is mounted on a drive shaft of the main machine, while a second gear is mounted on a numbering impression cylinder of the numbering device. The two gears are engaged when the numbering device is slid towards the main machine and disengaged for the opposite direction of movement of the numbering device. A detent mechanism is provided for fixing the numbering device in either the engaged or disengaged positions of the gears.
