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.
A mechanism for the automatic control of printing machines, particularly accessory devices for additional printing, and wherein the single functions are carried out in predetermined intervals according to the working cycle of the printing machine, the mechanism having a double-peripheral cam about which there are arranged a plurality of two-arm levers mounted on fixed pivots, connected to a first two-arm lever which is swingably arranged on a first pivot there is connected by means of a first pull rod the mechanism of an inker unit, a second two-arm lever being mounted on a second pivot, the second two-arm lever being rotatably mounted on a fixed structure of the printing machine, the second pivot being connected by means of a second pull rod with the mechanism for producing printing pressure, and a third two-arm lever which is swingably arranged on a third pivot, the third two-arm lever being connected by means of a third pull rod with the mechanism for the progressive changing of the numbers in the numbering devices of the printing mechanism.
