Abstract: An apparatus and method for stuffing envelopes is disclosed. The apparatus includes a plurality of prime movers, a plurality of sensors disposed throughout the apparatus, and a central controller. The prime movers, the sensors and the central controller are operably interconnected such that the central controller directly receives signals from the sensors and from the plurality of prime movers for real-time control of at least one prime mover from the plurality of prime movers based upon determined movement of at least one of a discrete sheet of material, a stack of sheets of material or a stuffed envelope through at least a portion of the apparatus.

Abstract: An apparatus is provided for accumulating discrete paper or film objects traveling in a machine direction. A first accumulator element of the apparatus is rotatable about a first axis of rotation. A second accumulator element is disposed in confronting relationship with the first accumulator element and has a first, generally flat surface, and a first arcuate surface. Both of these surfaces are rotatable about the first axis of rotation and the first accumulator element has a first angular position that defines a first gap relative to the second accumulator element for receiving the objects there between. The first accumulator element has a second angular position that defines a second gap relative to the second accumulator element for moving the objects in the machine direction, with the second gap being smaller than the first gap.
