Abstract
A machine for printing flat objects of various thicknesses successively fed the length of a table by means of a feed mechanism and printed by means of a printing mechanism is provided. The feed mechanism includes at least two feed rollers between which the objects pass. Each of the at least two feed rollers is rotatable about an axis of rotation and at least one of the feed rollers is motorized. The printing mechanism includes a revolving printing drum and a motorized counter-printing roller rotatable about an axis of rotation. The machine also includes a lever having a first end, a second end, and a middle. The lever is pivotable at its middle and joined at its middle by a stop joint. The first end of the lever supports the axis of rotation of the counter-printing roller, and the second end of the lever supports the axis of rotation of one of the at least two feed rollers, such that shifting of the feed roller whose axis is supported by the lever, subsequent to the passage of an object between the at least two feed rollers, causes pivoting of the lever and thus a corresponding shifting of the counter-printing roller, if not already shifted by the passage of a preceding object.
