Title:
METHOD AND DEVICE FOR PASTING LABEL
Document Type and Number:
Japanese Patent JPS5974040
Kind Code:
A
Abstract:
A defect on a moving web (d) such as a printed sheet of paper is detected visually or automatically, and the type of the defect thus detected is marked by means of a stamping unit (22) on a label (b) of a label tape (c) consisting of a base strip (a) and a number of labels (b) removably secured to the base strip (a). Thereafter, the base strip (a) of the label tape is advanced and reversed abruptly in its moving direction, whereby the label (b) is partially separated from the base strip (a). The label thus partially separated is then pressed against the moving web (d) by means of a pressure roller (26). 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 (13) on a swing arm (19) in the direction of movement of the web. The label tape (c) is passed around the swing roller (13) and then directed downwardly. The swing arm (19) is supported by means of a spring (20), and when the swing roller (13) 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.
