Abstract (en)

[origin: EP0976674A1] The rotation rate speed (revs) approaches a previously set, aimed-at or intended value. The controller is set for the intended rev. counter value (NSOLL) operated through the drive motor. The feed-path tension value is also set (FSOLL). A sensor measures the actual value of the paper tension (FIST) in the path. The tension controller is connected to this sensor and to the set intended values. The revolution speed controller is connected to the output (NSOLL) of the tension controller.
