ABSTRACT:
In the stepwise feeding of a packing material web for the application of cover strips over prepunched pouring openings, the pouring opening is sensed by means of a photocell which is located at as great a distance from the point of application as the distance between two pouring openings. Any errors in this distance will thus affect the accuracy of application. In order to avoid this is proposed in accordance with the invention to sense the passage of the actual pouring opening and start a countdown sequence, at the end of which the web feed is interrupted with the pouring opening in correct position for the application of the cover strip. An arrangement for the realization of this, seen in the direction of feed of the material web (1) comprises a sensing device (4), a processing device (5) and a forward feeding device (9) which are connected to a control unit (13).
