Abstract
The invention provides a method of bonding into an integral structure a unit formed by disposing therein a heating wire and a temperature detecting wire, a surface cloth material of an electric carpet to be manufactured, and an insulating material of the same, wherein a metallic foil is used in the unit, the metallic foil itself is caused to generate heat by electromagnetic induction, at least one heat-fuseable film layer is melted by the generated heat, and the carpet elements are integrally bonded by pressing. The method provides for efficient bonding as well as the elimination of pile-collapsing of the surface cloth material, thus producing electric carpets of high quality.
