Abstract

The present invention describes a rolling tool device for compression rolling of, in particular, blade elements of a rotor area of a jet engine provided with a tool carrier. The tool carrier is connectable to a carrier spindle. Furthermore, two pliers-type bodies are rotatably connected to the tool carrier. The pliers-type bodies are each provided with a rolling area, with a distance between the rolling areas being variable in dependence of the rotary movement of the pliers-type bodies. In accordance with the present invention, an axis of the carrier spindle in the state connected to the tool carrier passes between the rolling areas through a contact point present at a distance between the rolling areas equal to zero.
