<p>A clamping device for releasably clamping a sheet which is fitted around the peripheral surface of a drum (1), with the aid of two clamping bars (10), the clamping bars (10) extending axially along the drum (1) and being able to be moved essentially in the radial direction between a clamping position and a release position, and there being provided, for each clamping bar (10), underlying clamping parts (11). Each clamping bar (10) is movably connected to a sliding element (12) which can move essentially in the radial direction and is provided with a locking mechanism for locking the sliding element (12) in a first or second locking position, intermediate means (13) being arranged between the clamping bar (10) and the sliding element (12), which intermediate means (13) press the clamping bar (10), at least in one of the two locking positions of the sliding element (12), against the underlying clamping parts (11). <IMAGE></p> |
