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 ).
