There is disclosed a sheet re-circulating accumulator (10) comprising: an inlet feed path (20) to an accumulation location (30); an outlet feed path (40); a sheet circulation path (60) defined by stationary sheet guide means (62, 64, 66, 68); and sheet driving means (32, 70, 72, 74, 76) associated with the sheet circulation path (60) for selectively advancing a partial accumulation (P) of one or more sheets (S) at the accumulation location (30) around the sheet circulation path (60), so that the partial accumulation (P) is guided by the stationary sheet guide means (62, 64, 66, 68) at the leading edge of the partial accumulation (P) while being driven, and back to the accumulation location (30) to accumulate the next sheet (S) fed from the inlet feed path (20) with the partial accumulation (P), and delivering an accumulation (A) of sheets (S) along said outlet feed path (40).
