An accumulator is used with a duplicating device such as a duplicating machine having an upper level conveyor for transporting single sheets of paper and a lower level working area for processing the sheets and includes a frame positioned at an angle to the horizontal which receives single sheets from the upper level conveyor, a gate bracket communicating with the frame, a gate extending across the gate bracket and rotatably mounted thereto, upper and lower front pinch rollers positioned in front of the gate, and upper and lower rearward rollers. The upper front and rearward rollers are connected by a linkage so that they are maintained at the same distance above their respective lower rollers when the front pinch rollers engage a set of sheets. Single sheets accumulate in a set against the gate and are held together by the upper and lower front pinch rollers. The gate opens and the front pinch rollers propel the set of sheets between the rearward rollers to the working area.
