<p>In the field of mailpiece handling apparatuses, it is known to provide machines having DC drives for all components thereof. However, the use of DC drives exclusively is expensive. On the other hand, DC drives frequently do not provide a sufficient degree of precision in the controlling of mailpieces in the machines. The disclosure relates to a folder-inserter-sealer machine (10) having a first, AC electric motor (28) connected to drive a first set of drivable components on the apparatus; and one or more further, DC electric actuators (18;27) operatively connected to drive a further set of drivable components of the apparatus. An advantage of the arrangement is that precise control of components may be obtained in a comparatively low-cost machine. <MATH></p> |
