A rotor (10, 11) of a creaser (1) including contact means (30, 27) to secure the web of the material to be creased (5 to 7), drawing it radially against its circumference, the positive contact pressures of which are adjustable over the pass and the working width and the position of which in relation to the rotor means and/or any tools (22, 23 and/or 26) provided on the same is variable, thus allowing a multitude of adaptations to the creasing unit (8) to be provided. Control may be effected mechanically by gears and/or adjusting baffles for the vacuum.
