Abstract (en)
[origin: EP0620087A1] Method for perforating films, characterised in that it consists mainly in the fact that successive series of perforations are made by means of heated sleeve tubes (10); the small discs (32) cut out are grasped; and these small discs (32) are moved away from the film (2) in this way, so that they are actually cut away. <IMAGE>
