BELT-DRIVEN DOCUMENT ACCUMULATOR HAVING BELT-DAMPENING TABLEAND SIDE GUIDES

摘要

The invention relates to belt-driven ramp document accumulators. Prior accumulators typically jam at very high speeds. The document accumulator of the present can operate reliably at high speeds without jamming. The document accumulator (1) includes first (55, 61) and second (57, 59) outer belts extending between first and second pulleys for contacting and transporting a document, and an inner belt (65, 67) 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 belt-dampening table (51, 53) having a horizontal surface adjacent to a horizontal reach of the inner belt is provided for dampening oscillations of the inner belt which occur at high speeds.
