Definitions
- N preselected positions and/or N preselected profiles of positions and/or N reseieuieu lurce values and/or N preselected profiles of force values are stored in the thread braking device in an ascending to descending order and the operator selects a number between 0 and N for having a higher or lower radial stiffness without having to know the position or force associated with the selected number.
- the interface comprises for example a turnable knob for selecting the radial stiffness between a level 0 and a level N, with 0 being the lowest level of radial stiffness and N being the highest level of radial stiffness.
- the interface in one embodiment also comprises a display to show the selected level.
