A second folding device effects a second fold to the folded bag, and a third conveyor positions the twice folded bag onto a third stationary support surface. A third folding device is provided for imparting a third fold to the twice folded bag, and it includes an orientation support frame to position the bag for transferring same to a collector trough.
