The invention relates to a method and a device for orienting flat items of mail towards a narrow edge in a U-shaped conveying channel ( 3 ) in which they are conveyed in an upright position and without being jammed. Before the items ( 1, 2 ) pass the conveying channel ( 3 ) for the purpose of alignment, their thickness is measured. The distances of the lateral limit stops or limiting sections are changed by means of adjusting mechanisms ( 7, 8, 9, 10 ) for every item of mail ( 1, 2 ) in such a manner that at the end of the conveying channel, the item is oriented towards its lower narrow edge by virtue of its own gravity and the distance of the lateral limit stops ( 4 ) of the conveying channel ( 3 ) from every item of mail ( 1, 2 ) during transport through the conveying channel ( 3 ) is only wide enough for the item not to collapse at all nor to collapse partially even if its intrinsic stiffness is poor.
