a high speed gravity feed can conveyor comprises two facing c - shaped guides formed of hard chrome plated sheet metal . the guides are held in opposed spaced relationship by open u - shaped collars distributed along the conveyor . the collars distributed along the conveyor . the collars are formed with openings positioned downward having sufficient width to pass a can turned from a rolling orientation in the conveyor . the edges of the c - shaped guides are turned in a direction to support a rolling can and are covered with ultra - high molecular weight plastic to minimize rolling friction and protect the metal surface . the facing guide surfaces with chrome plating reduce sliding friction when a can end contacts a guide and reduce the potential for nicking the surface .
