A universal assembly machine manufactures conventional buttons with formed backs. The machine comprises a rotatably indexable die table to which are mounted pickup and crimp dies. The die table indexes about a center column of the machine frame. A ram die is advancable and retractable in a pickup stroke and a crimp stroke by means of a handle. The ram die includes a ram outer ring that is rotatable by means of a shifter post joined to the die table. Indexing the die table causes the shifter post to rotate the ram outer ring into a pickup mode or a crimp mode to suit the ram pickup and crimp strokes, respectively. The universal assembly machine also manufactures buttons with flat backs by using a different crimp die pedestal than is used with the formed backs. An adapter on the crimp die pedestal used with formed backs allows that crimp die pedestal to also be used for manufacturing buttons with flat backs. The invention also embraces button medallions. A flat back button is loaded into the pickup die, and the die table is indexed. The ram die is advanced in a third press stroke to bend the shell frusto-conical wall of the flat back button inwardly to be flat and parallel to the flat back.
A universal assembly machine for manufacturing buttons and button medallions from a flexible sheet, a shell, and a back comprising:
