an apparatus for uniformly distributing parts on a conveyor surface which includes a storage bin for holding randomly oriented parts in bulk , a conveyor adjacent the storage bin for acquiring a fragment of the randomly oriented parts in the storage bin and delivering that fragment of randomly oriented parts to a chute , a vibratory conveyor receiving the fragment of randomly oriented parts from said chute , and a belt conveyor for receiving the randomly oriented parts from said vibratory conveyor . the vibratory conveyor includes at least one rib projecting upward therefrom and extending across at least a section of the vibratory conveyor perpendicular to the direction of conveyance , the at least one rib acting as a flow obstruction to cause the randomly oriented parts traveling on the vibratory conveyor to gather and spread across a width of said vibratory conveyor to thereby spread more uniformly on the vibratory conveyor after passing over the at least one rib .
