ABSTRACT:
The invention relates to a method for positioning webs of film of a packaging device, according to which goods are introduced into a first web of film in troughs, a second web of film is withdrawn from a supply of web against the resistance of a brake and is placed on the first web of film and interlinked with the same, the advance of the second web downstream of the supply of web being detected by a first optical recognition means. In order to exactly position the two films one on the other, a second recognition means is provided that detects any dimensional errors, thereby changing the position of the first recognition means relative to the direction of conveyance of the second web of film.
