Abstract
A process for manufacturing head surfaces of dies cooperating with cylindrical press rolls for rotary presses. To avoid the high Hertzian stresses occurring dies for rotary presses during the interaction of the die head and the press roll, the present invention provides for designing instantaneous surface lines of the press roll extending through the instantaneous contact points between the head surface of the die head and the press roll under the action of the press roll on the die head as a set of continuously consecutive contact lines on the head surface of the die head by a tool.
