Abstract
An improved sheet accumulator for stacking serially fed sheets transported on a paper path includes a guide deck. Above the guide deck, a plurality of parallel belts are positioned to provide a driving force for sheets on the deck. Within the accumulator, a ramp apparatus is positioned across the paper path whereby sheets driven by the belts on an upstream portion of the accumulator deck are driven over the ramp apparatus and deposited in an accumulating region of the accumulator deck on a downstream side of the ramp apparatus. Sheets are stopped by an accumulator stop mechanism located at a downstream end of the accumulating region that prevents movement of sheets by the belts while sheets for an accumulation are being collected. When an accumulation is completed, the accumulator stop mechanism allows sheets to be transported from the accumulating region.
