Beschreibung
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. L'invention concerne un tambour et son procédé de fabrication, notamment le scellement du sertissage situé entre la paroi terminale et le corps, que l'on obtient au moyen d'un filament (1) de plastique déformable. Ledit filament est placé dans un préroulage (2) du bord (3) de la paroi terminale, et transformé par déformation en un anneau fermé pendant l'opération de sertissage, sous l'effet de la chaleur dégagée par cette dernière, remplissant la partie centrale du sertissage, inerte par rapport au contenu du tambour, et capable de coller à l'acier de ce dernier.
