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 method and apparatus for applying both a layer of resilient sealing compound to the curls of ends of cans and a thin layer of end repair coating over the inside bottom surface of can ends before the ends are assembled onto the body. The compound is applied by forcing it as a very heavy viscous liquid under high pressure through an extrusion nozzle under conditions which result in a coating of compound being evenly applied to a peripheral groove of the rotating can ends while simultaneously the end repair coating is sprayed onto the inside bottom surface. In the preferred embodiment both the compound and the end repair material are applied to the can end while it is rotated in a vertical plane about a horizontal axis.

Abstract: METHOD AND MEANS FOR COATING THE INTERIOR CYLINDRICAL SURFACE OF OBJECTS SUCH AS METAL CANS FOR FOOD, BEVERAGES AND OTHER SUBSTANCES WHICH NEED PROTECTION AGAINST INJURIOUS REACTION WITH OR POLLUTION FROM CONTACT WITH THE MATERIAL OF THE CAN. RAPID AIRLESS SPRAY COATING OF SUCH SURFACES, WHILE THE SURFACES ARE REVOLVING AT HIGH SPEED, FROM A STATIONARY SPRAY NOZZEL EXTERNAL OF THE CAN, BY PROJECTING A SPRAY HAVING AN ASYMMETRICAL PATTERN INTO THE SINGLE OPEN END OF A CAN HAVING ONE CLOSED END, WITH THE PATTERN OF FLOW EMERGING FROM THE NOZZEL BEING MATCHED TO THE INTERNAL SURFACE CONFIGURATION TO APPLY A UNIFORM COATING. ALSO DISCLOSED ARE SPRAY NOZZELS HAVING THEIR OUTLET ORIFICES DESIGNED TO PROVIDE DESIRABLE SPRAY PATTERNS FOR USE IN THIS METHOD OF SPRAYING, AS WELL AS METHODS FOR MAKING AND SHAPING THE OUTLET ORIFICES.

Abstract: An apparatus for applying an impervious protective coating over the seams of cylindrical metal can bodies either before or after the seams are welded, soldered, or cemented and prior to spray coating the complete interior of the bodies. The apparatus is operable to intermittently apply 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 apparatus includes a new and improved airless spray nozzle which is operable to atomize the spray nearer the nozzle than has heretofore been possible. It also includes a pair of air jets located on opposite sides of the spray and operable to confine the atomized spray or fog to the seam of the can so that little or no excess material is sprayed onto that portion of the can located adjacent the seam.

Abstract: Method and means for coating the interior cylindrical surface of objects such as metal cans for food, beverages and other substances which need protection against injurious reaction with or pollution from contact with the material of the can. Airless spray coating of such surfaces revolving at high speed by stationary spray nozzles external of the can. The nozzles project impinging airless sprays having desirable patterns through respective ends of open ended can cylinders into longitudinally elongated contact with the interior surface.
