Abstract: A method and apparatus for applying an impervious protective coating over the inside seam of a cylindrical metal can body either before or after the seam is welded, soldered or cemented and prior to spray coating the complete interior of the body. The apparatus is operable to practice the method of intermittently applying an airless spray to the interior seams of the cans as they continuously move past an airless spray gun secured to the end of a stubhorn of a can forming line. The nozzle orifice size and the nozzle orifice pressure are so selected and the nozzle so positioned and controlled that a thin smooth impervious layer of atomized spray is applied over the seam with a minimum of excess material being sprayed onto the seam surface and a minimum of waste material being sprayed past the seam surface.

Abstract: A pneumatically controlled color change system for use with automatic multi-color paint spray apparatus and the like wherein an entirely pneumatically controlled system employing a pneumatic timer including pneumatic sequence valves controls a quick-color change system in which a plurality of colors of paint are connected to various inputs of a manifold, each through a check valve which isolates each of the manifold ports from each other and in which a source of solvent is connected to another input of the manifold. An exceedingly high-speed system is provided in which a metered charge of solvent only partially filling the system is injected through the manifold and forced through the system with the new color to be selected, thereby purging the system of the old color. High-speed valve timing is provided in the order of magnitude of 1 second per valve of the sequence.
