摘要: A method and apparatus for controlling web tension in a printing press having plurality of sets deformable nip rollers, each set driven by separate driver, the passing sequentially through rollers forming segment therebetween. The driver downstream is adjusted to first controller adjusts characteristic upstream maintain second constant. Alternatively, sensor measures based on measurement from sensor.
