Procédé de fabrication d'un cadran d'horlogerie et cadran obtenu par ce procédé

摘要

A depression in the die is filled with a liquid or pasty substance which supports the dial blank. A descending punch pushes the blank part way into the depression causing the substance of the cushion to force the blank into the punch hollows corresponding to the symbols to be raised. The die depression is surrounded by an upstanding rim that penetrates part way into the blank when the latter is pressed by the punch.
