<p>The device has an unloading device (4) provided with a set of functional parts (6, 8). An adjusting body (16) fixes a clamping body (14) against a movement radially outside in such a manner that the clamping body supports the functional parts in an axial direction. An operating device e.g. actuator (12), is operated in the axial direction and directly or indirectly fixes the adjusting body against the movement in an unoperated functional position and enables the movement of the adjusting body in an operated functional position.</p> |
