ABSTRACT:
A device for measuring web tension of a continually movable web transported on a rotated cylindrical roller of a printing machine includes two eccentrics connected to two ends of the roller for supporting the latter for rotation and each includng a supporting pin. The supporting pin of one of the eccentrics has its end rigidly connected to a machine frame and is able to twist proportionally to the web tension. A lever having one end rigidly connected to the twistable supporting pin has its other end positioned between a light transmitter and a light detector of an optoelectronic sensor which detects the amount of twisting of the supporting pin.
