Therefore, only the thermoplastic synthetic resin layer in contact with the metal foil is selectively heated. The carpet is heated evenly and high temperatures do not reach the carpet. The slit in the metal foil is expanded by the forming force during molding, and the softened thermoplastic synthetic resin layer leaks out from the slit and adheres to the insulator. Furthermore, since metal foil has a heat-insulating effect as described above, a molded carpet with good heat resistance can be provided, and the metal foil also improves sound insulation properties.

して成形カーペット（１２）が得られる。The carpet laminate (11) produced in this manner has the structure shown in FIG. 3, and the back side of the carpet laminate (11) is heated with far infrared rays or high frequency waves. The metal foil (4) is heated by radiation or dielectrically by the above method, but the metal foil (4) has a small specific heat and a high thermal conductivity, so the heating of the metal foil (4) is extremely rapid and uniform. , the local heating is eliminated and the high temperature does not reach the carpet (1) but the metal foil (4).
) Only the thermoplastic synthetic resin layer (2) in contact with is selectively and uniformly heated and softened. In this state, the carpet laminate (11) is set in a press mold (8) into which an insulator (3) made of felt, polyurethane foam, etc. is inserted, as shown in Figure 4, and then molded as shown in Figure 5. Press molding using a mold (8). At this time, a forming force is mainly generated as shown by the arrow in Fig. 5, and the metal foil (4) is pulled by the forming force and slits (4) are formed.
1) is expanded, and the heat-softened thermoplastic synthetic resin layer (2) leaks from the slit (41) and adheres to the insulator (3) as shown in FIG. A molded carpet (12) is thus obtained.
