An accumulator device with a downward angled input transport. Downstream, an accumulating receptacle receives sheets. The accumulating receptacle has an upper guide and a lower guide forming a horizontal accumulating channel. Dump rollers act as a stop during sheet accumulation, and as a transport for removing completed accumulations from the sheet accumulating device. A rear portion of sheets buckle downward into a trap arrangement below the input rollers. Preferably, the upper guide of the accumulating channel comprises a continuously rotating belt to urge accumulating sheets against the dump rollers. Also, a positive air device may be used to assist in the buckling of the rear portion of the sheets. To assist in handling large collations, when a sheet arrives at the dump rollers the advance by a small predetermined incremental displacement slightly shingling the sheets to maintain positive control for later reliable discharge.
