ABSTRACT OF THE DISCLOSURE A drum with sealed end closures and the method of forming the drum in which a tubular shell is formed to define drum side walls. An end closure is applied to at least one end of the shell with the adjacent peripheral edges of the shell end closure being formed into a circumferentially extending chime with the peripheral edges defining said chime being in abutting surface-to-surface contact and folded to provide a seam with five layers of material of said edges being in a transverse radial direction. The chime is thereafter formed into a reinforced chime folded to provide a seam of predetermined shape with seven layers of material of the edges being in a transverse radial direction and having increased sealing, handling, and strength characteristics while retaining a minimum desired length for the seam.
