ABSTRACT:
A defect on a moving web such as a printed sheet of paper is detected visually or automatically, and the type of defect thus detected is marked by means of a stamping unit on a label of a label tape consisting of a base strip and a number of labels removably secured to the base strip. Thereafter, the base strip of the label tape is advanced and reversed abruptly in its moving direction, whereby the label is partially separated from the base strip. The label thus partially separated is then pressed against the moving web by means of a pressure roller. At the instant of pressing of the label against the web, abrupt variation in tension of the label tape occurs, which variation or shock is absorbed by movement of a swing roller on a swing arm in the direction of movement of the web. The label tape is passed around the swing roller and then directed downwardly. The swing arm is supported by means of a spring, and when the swing roller is moved, the spring is extended. The absorption of the shock prevents any adverse effects such as tearing and wrinkling of the label being affixed.
