ABSTRACT:
A method and apparatus for the centerless winding of webs has a pressure cylinder which lies on a wind-up roll, both of which are mounted on vertical movement. The vertical movement of the carriage mounting the wind-up roll is modulated by coupling the vertical movement of the pressure cylinder therewith such that the carriages follow the movement of the pressure cylinder to a degree corresponding to the momentary degree to which the wind-up roll has been wound.
