<p>Process and apparatus for laminating a substrate plate (2) with a plastic film (3), in which the following steps are carried out: a) the back side of the plastic film, which faces towards the substrate plate, is pretreated by means of a corona treatment in a corona system (4); b) an adhesive is applied to the back side of the plastic film in a contactless manner by means of nozzle application; c) the plastic film is laminated onto the substrate plate by means of a laminating roller (18) and a back-pressure roller (20) lying opposite the laminating roller on the back side of the substrate plate; wherein the plastic film is held with tension throughout the process up to lamination, and wherein the conveying speed of the substrate plates is 0.001 to 0.3 m/min higher than that of the laminating roller, wherein a time difference of at least 10 s is observed between the corona treatment of the plastic film and the application of adhesive, wherein a time difference of at least 5 s is observed between the application of a hot melt adhesive and the lamination, and wherein the relative humidity is regulated.</p> |
