Zusammenfassung:	The invention relates to a drum and its process of manufacturing, in particular the sealing of the seam between end wall and body which seal is obtained by means of a filament (1) of a deformable plastic which is placed in a precurl (2) of the end wall flange (3) and during the seaming operation as a result of the heat developed therewith is deformed into a closed ring which fills the core of the seam, is inert with respect to the contents of the drum and capable to adhere to the steel of the drum.
