Abstract: A substrate web (1), which is to be laminated on both sides with laminating webs (10) and (18), is brought together with and joined to a laminating web (10) coated with an adhesive film (8) in a roller gap (2) formed by two counterrollers (3) and (4). The other side of the substrate web (1) receives an adhesive film (9) from the second counterroller (4) in the roller gap (2). The second laminating web (18) is brought together with and bonded to the side of the substrate web (1), which side is coated with the adhesive film (9), in a roller gap (16) formed by a first laminating roller (15) and a second laminating roller (17).
