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.
