Abstract
The tool set comprises a male die and a female die cooperating to connect metal sheet workpieces when driven by a press. The male die is trunconical. The female die includes an anvil and forming members which, in a first operation phase, are stationarily supported and, in a second phase, are subjected to a movement in the same direction as the male die, thereby simulating the effect of a double stroke press.
