ABSTRACT:
A document accumulator comprising for high-speed document assembly includes first and second pulleys, a first outer belt extending between the first and second pulleys for contacting and transporting a document, a second outer belt extending between the first and second pulleys, and extending generally parallel to and horizontally displaced from the first outer belt, for contacting and transporting a document, and an inner belt generally parallel to and horizontally displaced from both the first and second outer belts such that it lies between the first and second outer belts. A first side guide has a first vertical surface adjacent to a horizontal reach of the first outer belt, and a second side guide has a second vertical surface adjacent to a horizontal reach of the second outer belt. A belt-dampening table having a horizontal surface adjacent to a horizontal reach of the inner belt is provided for dampening oscillations of the inner belts which occur at high speeds. At least two ramps for performing over- and under-accumulation are each mounted on a shaft connected at each end to a rotating assembly. Cam-type release levers permit the rotating assemblies, and thus the ramps, to be rotated and translated without the use of tools.
