Abstract: 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.

Abstract translation: 模具中的凹陷填充有支撑拨号盘的液体或糊状物质。 下降的冲头将坯件部分地推入凹陷中，导致衬垫的物质将坯料压入与要升高的符号相对应的冲孔中空部分。 模具凹陷被直立的边缘包围，当凸缘被冲头按压时，其直接穿过坯件。
