Abstract
A system for controlling friction forces acting on a mailpiece in a mailpiece insertion module. The system includes, a backstop assembly for arresting the motion of the envelope when disposed in a first positon and permitting conveyance along the feed path when disposed in a second position, an actuator operative to position the backstop assembly into the first and second positions and consuming energy to maintain the backstop assembly in the first position, a sensor for acquirinq data indicative of the magnitude of energy consumed by the actuator; a means for developing a pressure differential across the envelope to urge the envelope into frictional engagement with a plurality of drive belts and for developing friction forces along a mating interface, and a system controller, for varying the magnitude of the pressure differential and the friction forces developed along the mating interface of the envelope.
