Abstract:
1. A sheet turning unit comprising: a first sheet conveyor device for transporting a sheet at least along a first transport path in a first plane; a second sheet conveyor device for transporting the sheet along a second transport path, said second transport path extending at an angle of 90° with respect to the first transport path and describing a curve of 180° , wherein a starting point of said curve is located in the first plane and an end point of said curve is located in a second plane that is different from the first plane; and a third sheet conveyor device for transporting the sheet along at least a third transport path; wherein at least one of the first or third sheet conveyor devices, respectively, comprise at least one sheet transport body that can be rotated, by means of a rotating mechanism arranged in the sheet transport body, about a first and a second rotational axis, said axes extending through one point of intersection and being perpendicular to one another, wherein the sheet transport body can be driven for rotation about at least one of the rotational axes by means of a driving mechanism and a driving motor connected therewith, and wherein the driving mechanism comprises a freewheel arranged between the sheet transport body and the driving motor.
