A turning device for a sheet-fed printing press contains a turning pocket (9) which is bordered by two walls (10,11) which in the interior of the turning pocket are situated close together and which at an opening side of the turning pocket are a predetermined distance from each other forming an elongated sheet intake and output opening (12) with two edges parallel to each other. The simply constructed, reliably functioning sheet-turing device includes: a plurality of oblong elastic drivers (17) that are movable along a concave path with respect to the interior of the turning pocket (9) from one edge of the sheet intake and output opening (12) to the other and that extend lengthwise transversely to the concave path; at least two counterpressure elements (15,16) each of which is located close to an edge of the sheet intake and output opening (12) in a position along the concave path through which a tangent to the concave path into the interior of the turning pocket (9) is directed, the counterpressure elements being impacted by some of the elastic drivers (17); and a sheet stop (18) in the turning pocket, whose distance from the counterpressure elements (15,16) is somewhat less than the length of the sheets which are to be turned.
