Conveyor system for passing coated cans through chamber

A conveyor system for conducting objects which are cans having a fresh coating thereon through a chamber for treating said can coatings and for concurrently rotating these objects to optimize said treatment, said system comprising:

• A. an endless belt for conducting said objects through said chamber and having rotatable pins mounted thereon, the pins extending laterally from the belt, one end of the pins having means thereon for supporting said objects, the other end of each pin having a sprocket wheel secured thereto;
• B. an endless sprocket chain disposed in parallel relation to said belt, said chain being engaged by the sprocket wheels mounted on said pins;
• C. first variable speed drive means operatively coupled to said belt to cause movement thereof in a predetermined direction to advance said objects through said chamber at a desired speed;
• and
• D. second variable speed drive means independent of said first means and operatively coupled to said chain to cause movement thereof in a selectable direction to cause the pin-borne objects to rotate at a rate determined by the relative speeds of said belt and said chain and in a direction determined by the selected direction.
