At the device for transportation of shifted flow of paper sheets, which is usable for polygraph machines, there are sheets (25) located on perforated conveyor belts (3, 4) of the belt conveyor, which circulate around the whole device, equipped on the upper side with an upper metal cover sheet (2), in which, under each perforated conveyor belt (3, 4), there is a row of holes (2.1) and pair of laterally shifting collars (7). The upper metal cover sheet (2), which forms the conveyor table, is fixed on the upper side of the grid support (1), equipped with internal ribs (1.1), which form three longitudinal, mutually separated vacuum chambers (10, 11), closed by bottom metal cover sheets (8, 9) and connected to the common source (22) of vacuum. Above each peripheral vacuum chamber (10) there is one perforated conveyor belt (4) and above the central vacuum pressure (11) there are two central perforated conveyor belts (3).<IMAGE>
