郭に塩化ビニル外被11を使用した。Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a heat insulating felt, and an aqueous emulsion adhesive 5 is continuously applied to the heat insulating felt 1 by a roll coater 6. Reference numeral 2 denotes a raised surface cloth, on which the aqueous emulsion adhesive 5 is continuously applied by a roll coater 6. The raised hair cloth includes tufts, bores, moquettes, and meshers. 7
Is an electrode plate. 13.56 MHz is applied to this electrode plate 7 by a high frequency power supply 8.
Of the aqueous emulsion adhesive 5 sequentially fed was sequentially heated from the end.
The adhesive used was an ethylene-vinyl acetate copolymer. Reference numeral 3 denotes a flexible linear heating wire, which is a heater unit using the nonwoven fabric 4 as a base material. The nonwoven fabric 4 is as thin as about 15 g / m 2 . The heater unit was located outside the electrode plate 7 and was not affected by the high-frequency electric field. Immediately after heating the surface of the water-based emulsion adhesive 5 of the napped surface material 2 and the surface of the water-based emulsion adhesive 5 of the heat-insulating felt 1, a heater unit was sandwiched and sequentially pressed by a pressure roller to be integrated. FIG. 4 shows a flexible linear heating wire in which a vinyl chloride jacket 11 is used around the heating wire 10.

いう効果がある。In the above method, the water content of the ethylene-vinyl acetate copolymer aqueous emulsion adhesive 5 has a particularly high dielectric loss and is heated in a short time to evaporate by boiling, and the solid content is also heated, and the solid content is a thermoplastic resin. Has softened from. Therefore, immediately after heating, even if a heater unit made of a thin nonwoven fabric is interposed therebetween, the adhesive material having softened the fibers of the nonwoven fabric penetrates and is integrated. The reason why the heater unit is provided outside the electrode plate 7 is that the heating conductor of the flexible linear heating wire 3 and the vinyl chloride jacket are made of a material that easily generates heat under the influence of the high-frequency electric field. If the heater unit is placed on a heat-insulating felt and is passed through a high-frequency electric field, if the power is set too high, it may cause wire breakage due to abnormal heat generation of the heating conductor, or melting or cracking of the vinyl chloride jacket. To be Therefore, the high-frequency oscillation power must be suppressed, and it is difficult to sufficiently remove water, and the conditions are extremely limited. Therefore, positioning the heater unit outside the high-frequency electric field has an effect that sufficient power can be applied only to the adhesive.
