Abstract
A method and apparatus for transferring tabs to a continuous material web in connection with the manufacture of packaging material in conversion machines includes the use of a transfer wheel which is located between a supply station for tabs and a deposit station, in which the wheel is located in contact with the packaging material web. With the aid of retainer jaws displaceable in a circumferential direction of the wheel, and fixedly disposed abutments, the position of each tab transferred to the wheel is corrected before the tab reaches the deposit station, so that the transfer to the packaging material web takes place in accurate register with markings previously provided on the web. The method and apparatus is well-suited for use in connection with continuous material webs travelling at high rates of speed, such as 400 to 500 meters/minute.
