发明名称 A LAMINATION STATION FOR LAMINATING A PAPARBOARD OR CARDBOARD WEB
摘要 A lamination station for laminating a film to a web of paperboard includes a nip roller and a cooling roller. Between the rollers there is formed a nip which presses together the film and the web of paperboard with an interjacent molten polymer layer or adhesive layer disposed between the film and the web of paperboard. The film, the paperboard and the molten polymer lie, after the nip, in abutment against the cooling roller for a certain angle interval. The nip roller 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.
