ABSTRACT:
In a bag folding apparatus, a filled bag is moved through a bag closing station with the open end of the bag passing through a space bounded on the opposite sides by a pressure application band and a countersurface of a folding ledge. The open end of the bag projects above the folding ledge and a folding device turns the open end downwardly over the folding ledge against the side opposite the counter surface. The folding ledge is coextensive in the direction of the bag extending between its closed and open ends with the pressure application band, and the folding ledge is elastically supported from an overhead bar by stirrups so that a free space is available for folding the open end of the bag downwardly against the folding ledge.
