An index tab forming system sequentially forms index tabs to a plurality of sheets without replacing a blade die. The index tab forming system includes a rotary die cutteron which a long blade die that can form an index tab at any position of the sheet in the conveyance direction is mounted. Furthermore, the index tab forming system includes a rotational speed calculation unit configured to calculate the rotational speed of a conveyance roller pairbased on the rotational position of a die cut roller, a sheet position detection signal provided by a sheet detection sensor, the number of times of sheet conveyance, and a shift distance between respective index tabs and a conveyance roller control unit configured to control the rotational speed of the conveyance roller pairbased on the calculated rotational speed.
