A conveying device having a flexible member with inside and outside surfaces and first and second end positions forming inlet and outlet orifices. Support mechanisms disposed intermediate the inside and outside surfaces and a drive mechanism for engaging the flexible member and propelling it in a continuous closed loop such that the inside surface becomes the outside surface and the outside surface becomes the inside surface; that the relative shape and orientation of the first and second end portion is not altered; and, that the inside surface and the outside surface move in substantially opposite directions.
