<p>The unit (20) has a fixing unit comprising a clamping body acting on supporting elements (24) and admittable by an actuating device. A displacement unit is operated with a compressed air supply. Compressed air is fed into the displacement unit, so that the supporting elements are pneumatically actuated in a direction toward an extended position. The supporting elements are air-cushion-supported in a base housing (22) by the compressed air derived from the displacement unit. A flange body is arranged in recesses.</p> |
