ABSTRACT:
A control device for controlling the advance and the positioning of envelopes in an insertion machine includes a stepper motor (27) coupled in common both to means (20) for transferring empty envelopes towards said insertion station, and to means (40) for transferring filled envelopes to be ejected, and a circuit (70) for controlling and governing the speed of the motor, causing said motor to be driven on the basis of clock signals generated by a clock circuit (62) synchronously with mechanical commands within the machine, and governing the speed of the motor on the basis of defined numbers of motor steps as detected counting from the moment that an envelope ceases to go past an intermediate point on the transfer path, as determined by a detector (29). The invention is applicable to automatic mail processing.
