<p>A lamination station for laminating a film (120) to a web of paperboard (110) includes a nip roller (150) and a cooling roller (160). Between the rollers (150, 160) there is formed a nip which presses together the film (120) and the web of paperboard (110) with an interjacent molten polymer layer (130) or adhesive layer disposed between the film (120) and the web of paperboard (110). The film, the paperboard and the molten polymer lie, after the nip, in abutment against the cooling roller for a certain angle interval. According to the invention, the nip roller (150) is a shoe-press type roller, either comprising a pressure bar having several hydraulically operated pressure elements, or comprising one or several rigid pressure bars.</p> |
