    Abstract: The invention relates to a closed-loop control device and a method for the control of the cross-machine and/or machine direction profile of at least one quality feature in the paper manufacturing process with the aid of two sensors. The first sensor picks up a first measured signal of the cross-machine and/or machine direction profile of a first quality feature of the paper web produced. A second sensor picks up a further measured signal. The further sensor is suitable for picking up a quality feature that differs from that picked up by the first sensor, or measures the first quality feature. One or both sensors traverse the web separately. The sensors act through a controller on actuators leading to the feed line or lines for the suspension leading to the flowbox of the machine for controlling thereby the first quality feature of the process.
