Claim:
A production method of a decorative film comprising a step of, in a state in which a transparent resin film is laid on a surface of a laminate sheet in which a pattern layer is placed on one surface of a base film of a thermoplastic resin, on the pattern layer side, inserting the laminate sheet and the transparent resin film into between a pair of endless belts placed opposite each other, and conveying the laminate sheet and the transparent resin film, 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, and 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, wherein the laminate sheet is mounted and conveyed on one of the pair of endless belts running on peripheral surfaces of the first rolls in such an orientation that the base film is in contact with said endless belt, the transparent resin film is laid on the surface of the conveyed laminate sheet on the pattern layer side, and thereafter the laminate sheet and the transparent resin film are inserted into between the pair of endless belts, and wherein the transparent resin film is preheated by contact with a peripheral surface of a preheat roll urged toward the endless belt, and the transparent resin film is run 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 the laminate sheet.
