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.

Suction conveyor device for transporting flat items, and system for producing flat items comprising said type of suction conveyor

An apparatus for producing book blocks includes a station to dispense a sheet web that moves in longitudinal direction and can be imprinted. A printing station has two cylinders that rotate with a circumferential speed corresponding to the movement speed of the web and function to support in a contacting manner the web with their circumferential surfaces over a specified angle. Contactless printing heads are assigned to each cylinder, arranged at a distance to the circumferential surface of the associated cylinder, and positioned side by side and at least essentially transverse to the circumferential and rotational direction of the associated cylinder. The printing head faces are oriented substantially tangential to the associated cylinder and the center lines of the printing heads are oriented to project substantially radially to the circumferential surface of the associated cylinder. The web is guided so that when it rests on one cylinder, one side of the web is imprinted and when it rests on the other cylinder, the other side of the web is imprinted. A desired web tension is created in the printing station. A cutting station is arranged downstream of the printing station to cut the printed web in longitudinal and transverse directions to form sheets having a predetermined height and width. An overlapping station arranges the cut sheets into an overlapping formation. A station collects the sheets to produce stacks that form book blocks.
