Abstract
The franking value or stamp index wheels mounted in the franking head of the franking machine are adjusted by in each case one pinion, which meshes with the engagement tooth system of a rack. In addition, each rack is provided with a driving tooth system electromagnetically operated by adjusting rams and a retaining tooth system in which engage two retaining pawls. An electromagnetic drive engages and disengages the retaining pawls with the retaining tooth system when the machine main shaft is in the set position. A sensor monitors the engagement movement of the retaining pawls, so that an incorrect position of the racks and therefore an incorrect setting is detectable by the franking machine control unit.
