A suction conveyor device comprising a suction arrangement having a suction side on which low pressure is generated, continuously rotating flexible conveying means made of flexible flat material having holes, an inner side enabling the conveying means to move along the suction side, and an outer side for receiving flat items in the active area of the suction side, where the conveying means moves in the transporting direction, the suction arrangement and the conveyor means designed with a transport path width in the active range perpendicular to the transporting direction. The conveying means includes continuously circulating individual, single-piece, flexible conveying means, both lateral edges thereof extending in the transporting direction at a distance from each other being at least the same as the total width of the transport path such that the individual, single-piece flexible conveyor means extend over the total width of the transport path.
