Abstract: The conveyor system includes a guide mechanism defining longitudinally disposed sliding surfaces for guiding rib means secured to the conveyor belt for controlling vertical movement of the runs of the conveyor and in addition defines a slot for restricting lateral movement of the conveyor. This design provides accurate control of the positions of the conveyor, which thus serves to limit the space that must be provided for conveyor systems, particularly of those types that are quite long.

Abstract: Conveyor belt is composed of a plurality of mutually parallel spaced endless carriers guided over drums. At least one of the drums is driven. To the outwardly facing side of the carriers are fixed slats and to the inwardly facing side, opposite the slats, are fixed ribs. The ribs are identical and arranged at equal spacing. The driven drum has on its periphery axial grooves arranged with the same spacing as and shaped complementary to the ribs. The ribs engage in the grooves whereby the belt is driven without slipping.
