Patent ID: 7135085

Claim:
A production method of a decorative film, comprising: laying a base film of a thermoplastic resin on a pattern layer of a transfer sheet in which the pattern layer is placed on one surface of a carrier film; thermally transferring the pattern layer onto the base film, and thereafter stripping off the carrier film, thereby obtaining a laminate sheet in which the pattern layer is placed on one surface of the base film; laying a transparent resin film on a surface of the laminate sheet on the pattern layer side; preheating the transparent resin film by contact with a peripheral surface of a preheat roll, and running the transparent resin film so as to constantly contact a peripheral surface of at least one guide roll during a period between departure from the peripheral surface of the preheat roll and contact with an endless belt; and inserting the laminate sheet and the transparent resin film into between the pair of endless belts, and conveying the laminate sheet and the transparent resin film under heat and pressure, thereby obtaining a decorative film in which a transparent resin layer of the transparent resin film is placed on the surface of the laminate sheet on the pattern layer side wherein each of the pair of endless belts is stretched between a first roll for heating the endless belt and a second roll for cooling the endless belt, and wherein, the pair of endless belts are driven by rotation of the first and second rolls so that the endless belts run from the first roll toward the second roll on the side where the endless belts are placed opposite each other, the transparent resin film is conveyed in contact with one of the pair of endless belts running on peripheral surfaces of the first rolls, the laminate sheet is laid on a surface of the conveyed transparent resin film opposite to the endless belt, and thereafter the laminate sheet and the transparent resin film are inserted into between the pair of endless belts.
