A method and an apparatus for transferring tabs to a continuous material web in connection with the manufacture of packaging material in conversion machines must be put into effect at very high work rates and speeds, since the packaging material web is normally advanced at a speed of between 400 and 500 metres/minute. A method and an apparatus for reducing this concept into practice comprise a transfer wheel (1) which is located between a supply station (4) for tabs (5) and a deposit station (2), in which the wheel is located in contact with the packaging material web (3). With the aid of retainer jaws (9) displaceable in the circumferential direction of the wheel (1), and fixedly disposed abutments (13), the position of each tab (5) transferred to the wheel (1) is corrected before the tab reaches the deposit station (2), so that the transfer to the packaging material web (3) may take place in accurate register with markings previously provided on the material web (3). <IMAGE> |
