ましい。A thermoplastic resin film and a resin are used in the same manner as above,
When laminating, it is preferable to use a film made of the same resin as the thermoplastic resin foam sheet. This is because thermal welding is sufficiently performed. The heater used in the method of the present invention is preferably a glass tube or cartridge heater containing a nichrome wire with a circular or oval cross section and a long length (the same as or longer than that in the thermoplastic resin foam sheet). It is preferable to heat the thermoplastic resin foam sheet to a temperature higher than the melting temperature of the thermoplastic resin foam sheet, and to bring the thermoplastic resin foam sheet into direct contact with the surface of the heater to melt the surface.

図面に基ずし、て説明する。When the thermoplastic resin foam sheet is brought into direct contact with the heater surface in this way, the heating time is instantaneous, and the thickness of the melted foam sheet is extremely small, resulting in a decrease in the thickness of the laminated twilled laminated sheet (settling). less. Note that the surface of the thermoplastic resin film may also be brought into direct contact with the surface of the heater as long as it does not melt and break. In the method of the present invention, an endless belt is suspended between the nip roll for the thermoplastic resin film and the guide roll among the pair of nib rolls, and the end portion of the thermoplastic resin film is spread on the upper surface of this endless belt. Manufacturing of the laminated sheet is then started. Therefore, even if the thermoplastic resin film is extremely thin and stiff, it can be applied flatly to the top surface of the endless belt, and the thermoplastic resin film will not wrinkle when starting, and will be evenly welded and laminated. You can get what you want. Hereinafter, the method of the present invention will be explained based on the drawings.

There is. For example, the polyethylene foam sheet 1 and the polyethylene film 2 are long and medium-sized with a diameter of approximately 90 mm, and although not shown in the drawings, they are wound into a roll and rolled from a raw material suspended on a pedestal, and then fused. The resulting laminated sheet 9 is also wound into a roll. At the start of manufacturing the laminated sheet, the polyethylene film 2 is placed on the upper surface of the endless belt 7, which is placed substantially parallel to the surface of the polyethylene film 2, as shown in FIG.

ら良好な積層シート９を得ることができる。As the nip rolls 4 and 5 and the guide roll 6 rotate, the polyethylene film is guided by the endless belt 7 and reaches the nip roll 5, where it is pinched together with the polyethylene foam sheet 1 by the nip rolls 4 and 5. The heater 8 is heated to a temperature higher than the melting temperature of the polyethylene foam sheet, and melts the surface of the polyethylene foam sheet. The degree of melting varies depending on the temperature of the heater and the speed at which the laminated sheet is taken off, and is generally achieved by heating the heater 8 to 350 to 600 degrees centigrade and drawing the laminated sheet 9 at a rate of approximately 25 to 35 degrees per minute. A laminated sheet 9 is obtained. Polyethylene film 2
is compressed by the nip rolls 5 and adhered to the polyethylene foam sheet to produce the laminated sheet 9.
Since the guide roll 6 does not need to be in contact with the polyethylene film 2, it is moved downward as shown in FIG. In the method of the present invention, as described above, when laminating and welding a thermoplastic resin foam sheet such as a polyethylene foam sheet and a thermoplastic resin film such as polyethylene film 2, an extremely flexible and stiff thermoplastic resin film is attached to the upper surface of the endless belt. Since the surface of the laminated sheet is guided by Atsushi and guided by the heater 8 and is welded to the thermoplastic resin foam sheet whose surface has been melted, it is extremely easy to operate at the initial stage of manufacturing the laminated sheet. Since the laminated sheet 9 can be kept flat, wrinkles do not occur in the laminated sheet 9, and a good laminated sheet 9 can be obtained from the initial stage of production.
また、従来の方法に比して製造初期の融着不良品を生じ
ないので極めて好適である。Furthermore, compared to conventional methods, this method is extremely suitable because it does not produce defective products due to fusion bonding at the initial stage of manufacture.
