ABSTRACT:
Mechanism for the control of printing pressures in a printing machine, particularly the printing pressures exerted by accessory devices such as a unit for the numbering of the printing articles. A single mechanism controls the single functions of the printing mechanism, such as the bringing into pressure engagement and the disengagement of the printing cylinders, the control of the inking unit, the control of the numbering device, and also possibly of other mechanisms. Around the circumference of a double-cam, there are arranged a plurality of two-arm levers. A first two-arm lever, which is pivotally arranged on a fixed, pivot pin is connected by means of a first pull rod with the mechanism of the inker unit. A second two-arm lever is journalled on a second fixed pivot, the second two-arm lever being connected by means of a second pull rod with a mechanism for imposing printing pressure and releasing such printing pressure. A third two-arm lever is pivotally mounted on a third fixed, pivot and is connected by the means of a third pull rod with the mechanism for the progressive advance of the numbers printed by the numbering devices.
