ABSTRACT:
A method for heat-bonding interior material including heating one electrode of a high-frequency welder to about 100.degree. C. less than the melting point of the outermost interior finishing material. The increased temperature raises the susceptibility of the cushioning material to dielectric heating from a high-frequency oscillating voltage from the high-frequency welder. There is also disclosed a method for selecting a urethane foam as a cushioning material which is optimal for use with the disclosed heat-bonding method, by determining the specific gravity and the air permeability rate of the urethane foam.
