Method and device for wrapping packets of cigarettes |
| 摘要 |
<p>A method and device for wrapping packets of cigarettes, whereby a conveyor (3) for conveying the packets (2) and an actuating device (19) for activating a number of heat-seal elements (11) cooperate so that each heat-seal element (11) is brought into contact with a respective packet (2) at a given heat-seal station (10); the actuating device (19) operates in time with the conveyor (3) to keep the heat-seal elements (11) contacting the respective packets (2) for a time which is a function of the feed rate of the conveyor (3); and an automatic control device (37) interacts with the actuating device (19) to prevent the contact time from exceeding a given maximum length. <IMAGE></p> |
