ABSTRACT:
A method of manufacturing a trim cover assembly for a vehicle seat, in which a decorative strip preformed in a predetermined shape and a substrate are pressed and heated together by upper and lower dies of a high frequency wave welding apparatus, while a high frequency wave is applied thereto. The upper die has a working surface larger than the decorative strip and formed with a fine crimp and fine irregularity. Thus, the decorative strip is welded integrally to the substrate on the same level, to thereby produce a greatly advantageous and aesthetic trim cover assembly.
