A method that facilitates the automatic identification of the long edge or the short edge of the item of laundry by determining the lengths or the angles of the edge areas of the item of laundry extending from a lower corner of the item of laundry. It may be derived from the determined angles or lengths of the edge areas whether the respective edge area belongs to the long edge or to the short edge of the item of laundry. With this information, a targeted transverse or longitudinal feed of rectangular items of laundry may be carried out to a downstream inserting machine. The fully automated feeding of items of laundry to, for example, an inserting machine is carried out in a targeted way with either the long edge of the item of laundry extending transversely to the feed direction or the short edge extending transversely to the feed direction.
