A device is provided for aligning leading edges of sheets at adjustable front lays of a feeder wherein the sheets are fed one after the other against the front lays in a conveying direction perpendicular to the leading edges, the front lays being connected to a front-lay shaft so as to be fixed against rotation relative thereto. The front-lay shaft is, in turn, mounted in a first and in a second bearing of the feeder. A swivelling device connected to the front-lay shaft reciprocatingly swivels the front lays about a longitudinal axis of the front-lay shaft. The aligning device includes a bending device for benging the front-lay axis by acting steadily on the front-lay shaft for selectively adjusting the longitudinal axis of the front-lay shaft so that the longitudinal axis has a shape which, respectively, is curved in the conveying direction, curved opposite the conveying direction and rectilinear.
