Abstract

L'invention concerne un manchon élastique pour une presse à sabot possédant un diamètre intérieur réduit graduellement des deux extrémités jusqu'au centre, dans le sens axial. Ledit procédé consiste à étirer entre deux rouleaux le manchon constitué d'une matière élastique imparfaitement durcie ou non durcie, à déplacer les deux rouleaux en les éloignant l'un de l'autre tout en les défléchissant dans certaines directions, de sorte que leur partie centrale se rapprochent sous l'effet de la tension du manchon, et à durcir parfaitement, dans cet état, la matière élastique pendant la rotation du manchon en vue de la réduction graduelle du diamètre intérieur de ce dernier des deux extrémités au centre dans le sens axial.
