ABSTRACT:
A device for setting the prepayment values of printing wheels in a machine or franking mail envelopes and wrappers comprises in the case of each printing wheel a mechanical planet-wheel transmission system in which an eccentrically mounted pinion is in mesh with a ring-gear within a franking drum. The ring-gear is rigidly fixed to an annular sliding disc which is freely rotatable on the drum and coupled thereto by means of a clutch. A retractable stop is capable of maintaining the clutch in the disengaged position as soon as the drum begins its movement of rotation for one revolution. The angular amplitude of rotation is predetermined in response to the position of a unit for controlling the prepayment value setting of the printing wheel considered.
