<p>A regulating apparatus for obtaining a uniform sliver delivered by a carding machine includes an rpm setter connected to a roller drive of the carding machine for determining an operational speed for the drive, a signal generator for producing a first signal as a function of actual properties of the sliver and a PI-regulator having a component determining a regulating time constant. The PI-regulator is connected to the signal generator for receiving the first signal and for generating a second, regulating signal. Further, the PI-regulator is connected to the drive for applying the second signal thereto. A regulating time constant setter is operatively connected to the component which determines a regulating time constant. The rpm setter and the regulating time constant setter cooperate for adjusting the regulating time constant setter as a function of adjustments of the rpm setter, whereby the regulating time constant of the PI-regulator is varied as a function of the rpm of the fiber-engaging roller.</p> |
