Abstract
In a paper web feed unit of a rotary press, a paper web taken out of a paper roll is longitudinally cut into first and second cut paper webs, which are fed out toward the downstream side by a driven roller of a feed-out mechanism, and only the first cut paper web is passed through an angle bar section for transferring the traveling path of the first cut paper web. The paper web feed unit is equipped with a paper web traveling tension controller which comprises a dancer roller mechanism for independently applying a predetermined pushing pressure to each of the first cut paper web passing through the angle bar section and the second cut paper web not passing through the angle bar section, a detector for detecting the positions of dancer rollers moved in a synchronized manner, and a controller for receiving a detection signal output from the detector and for outputting a control signal to a motor for the driven roller in order to control the rotational frequency of the driven roller to thereby maintain each of the dancer rollers at a constant position.
