ABSTRACT:
Apparatus for swaging the tips of ballpoint pens comprises three identical working rollers each having a conical running surface and a conical or otherwise rotatively contoured working surface. The conical running surfaces roll on a conical seat whose apex coincides with the axes of the three conical running surfaces of the rollers, thereby to avoid slippage.
