Abstract

Abstract Translated from French a. Procédé pour fabriquer un article formé par emboutissage d'une feuille ou plaque mince ayant une rigidité relativement basse, dans la cavité d'une matrice à l'aide d'un poinçon. b. La feuille mince est emboutie pendant que sa surface opposée à une face de ladite feuille qui est mise en contact avec l'arête arrondie de ladite matrice se trouve abaissée sur ladite arête arrondie de ladite matrice pratiquement pendant toute la durée de l'emboutissage, en empechant ainsi la formation de rides sur ledit article formé. c. Fabrication de récipients destinés à contenir des aliments ou des médicaments. at. A method of making a formed article by stamping a thin sheet or plate having relatively low stiffness in the cavity of a die using a punch. b. The thin sheet is stamped while its surface opposite to a face of said sheet which is brought into contact with the rounded edge of said die is lowered on said rounded edge of said die substantially throughout the duration of the stamping, in thereby preventing the formation of wrinkles on said formed article. vs. Manufacture of containers intended to contain food or medicine.
