A can manufacturing method comprises applying a water-soluble resin sealing substance to the side and end seam edges of a can body blank and end plates, producing a thin layer of sealing substance on the side and end seam edges under hot drying atmospheres, seaming the side edges of the body blank including the end edges of the end plates to form a complete can, and subjecting the seamed portions to an applied heating to allow the layered sealing substance in the seamed portions to melt and unite the seamed portions. The apparatus permits a sealing substance to be applied on the side edges of a can body blank on the conveying path.
