ABSTRACT:
A device for clamping a sleeve placed onto a tube for winding and/or unwinding a two-dimensional web, which, due to the clamping effect of at least one of the clamping elements to be engaged with the sleeve, is effectively connected with the tube which is rotated and driven around a longitudinal axis. The device has a hollow cylindrical tube, the inside space of which is developed as a pressure chamber to be charged with a medium, while the tube is provided with several clamping elements distributed to one another both in the axial and in the circumferential direction, while the clamping elements each are provided with a pressurized thrust carrying piece which can be moved radially and slid toward the outside to engage the sleeve, which, upon corresponding depressurization, releases the sleeve and returns said thrust carrying piece to the starting position.
