Abstract: This machine for postage metering a flat object (6) such as an envelope or a label comprises a horizontal opening for inserting an object, leading to two stops (8, 9) at right angles, a device for holding the object by gripping it between a fixed upper ceiling (2) comprising a window (2′) and a lower plate (3) vertically movable by means of a drive mechanism, an ink jet printing device (1) whose nozzles are disposed inside the window (2′) of said ceiling, and a sensor (10) of the presence of an object in the vicinity of the corner of the stops (8, 9), which starts the drive mechanism of the plate (3) for gripping the object (6) and the printing cycle. A motorized transverse rake (4) moves the object (6), while it is gripped, in front of the printing device (1).

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.
