Plant and method for laminating corrugated cardboard

A plant for laminating cardboard by an adhesive plastic film, comprising:

• a supply station that comprises supplying means of rough cardboard sheets in a feeding direction;
• an application station arranged in the feeding direction and comprising an application roller that comprises heating means;
• and
• a loading station that comprises:
• loading means configured to move at least one bobbin of adhesive plastics film from a storage position, in which the at least one bobbin of adhesive plastics film can be stored, into an unwrapping position, in which the at least one bobbin of adhesive plastics film unwraps the adhesive plastic film, the loading;
• a motorized platform that is movable between the storage position and the unwrapping position and is configured to support the at least one bobbin of adhesive plastics film;
• at the unwrapping position, at least one unwrapping reel and a telescopic loading arm, wherein the telescopic loading arm is configured to extend telescopically when the motorized platform carrying the at least one bobbin of adhesive plastics film is at the unwrapping position, to harpoon the at least one bobbin of adhesive plastics film and place it onto the at least one unwinding reel in the unwrapping position;
• a calender access chamber extending inside the plant and configured to allow access of operators inside the plant;
• and
• an entrance for access from outside to the calender access chamber, wherein the entrance is formed at the storage position;
• wherein the application roller is configured to be partly wrapped in the adhesive plastics film to thermally activate, by the heating means, the adhesive plastics film which is partly wrapped around said application roller, in order to unwrap and apply the thermally activated adhesive plastics film to a rough cardboard sheet so that the adhesive plastics film adheres to the rough cardboard sheet to form a coated cardboard sheet and to advance the coated cardboard sheet along the feeding direction;
• wherein when the motorized platform is in the storage position, the motorized platform overlaps the entrance, preventing access to the calender access chamber;
• and
• wherein when the motorized platform is in the unwrapping position, the motorized platform opens the entrance, thus allowing access to the calender access chamber.
