The repeating step and the third repeating step may be performed separately, and also, the devices up to the take-up roller 26 of the devices of FIG. 4 may be repeatedly installed in order to continuously execute each repeating step. .

In each feed and transfer step by the apparatus configured as described above, the polyester film 10 or the polyester-attached aluminum foil 25 or the polyester and aluminum foil-bonded nonwoven fabric 35 toward the pressing rollers 51 and 52, and The aluminum foil 20, the nonwoven fabric 30, or the polyethylene foam 70 is supplied in contact with each other. At this time, the conveying conveyor may be provided separately, or may be conveyed through a leveling roller or a tension adjusting roller in the middle.

In each coating step, the polyester film 10 or polyester-attached aluminum foil 25 or polyester and aluminum foil-bonded nonwoven fabric 35 and aluminum foil 20 or nonwoven fabric 30 or polyethylene foam 70 are transferred as described above. Polyethylene (PE) is applied by an applicator 31, such as extruded from a T-die, between one side or the opposite side thereof, and in each series fusion step, to the flame 45 of the burner 40, which is a heating means. The polyester film 10 or polyester-attached aluminum foil 25 or polyester and aluminum foil-bonded nonwoven fabric 35 and aluminum foil 20 or nonwoven fabric 30 or polyethylene foam 70 and the fed fed by By uniformly heating the polyethylene (PE) therebetween, an aluminum foil 25 with polyester, a nonwoven fabric 35 with polyester and aluminum foil, or a composite functional reflective thermal insulating material 90 is produced.
