A roller or belt correction device for lateral alignment, during converting, of partly folded workpieces in a folder-gluer, consists of a lower structure above which is mounted an upper structure pivoting in the horizontal plane. This upper structure comprises a row of conveying elements which are in contact with the lower plane surface of the workpieces and which are driven by a distinct means at adjustable speed. The device comprises a guiding element which is parallely movable to a axis materializing the initial virtual line against which the workpieces have been previously supported in their upstream conveying path before being rotated in a conveying device. Applied on these workpieces, in the direction of the conveying elements forming an air permeable surface, is pressure chosen so that, added to the specific gravity of these workpieces, the resulting frictional force between the conveying elements and these workpieces is suitable to transmit to each of them a speed which is substantially equal to the speed of the conveying elements whatever the specific gravity of these workpieces may be.
