Abstract
The present invention provides a method for manufacturing laminated material which can remove ear portions of a resin film extruded from an extruding machine and can directly laminate the resin film to a substrate and can make the processing of end portions of a laminated material after lamination unnecessary. The present invention also provides an apparatus used for such a manufacturing method. In the method for manufacturing laminated material which laminates a resin film formed by extruding molten thermoplastic resin from a T-die to a substrate, a laminating film is formed by cutting ear portions of the resin film before lamination and the laminating film is laminated to the substrate. Further, the apparatus for manufacturing laminated material according to the present invention comprises heating means which preheats a substrate, a T-die which extrudes molten thermoplastic resin as a resin film, cutting means which forms a laminating film by cutting ear portions of the resin film before lamination, lamination rolls which laminate the laminating film to the substrate, and a cooling device which quenches the formed laminated material.
