Abstract
Abstract A method for making a decorative trim assembly with a dielectric embossing press in which one of the electrodes includes a plurality of spaced embossing blades and the other electrode has a flat face formed by a yieldable material. The method comprises the steps of preforming a sheet of thermoplastic material with a plurality of risers defined by spaced trim lines followed by placing the sheet on the electrode with the embossing blades contacting the trim lines. Afterwards, a coextensive sheet of filler material is positioned onto the sheet of thermoplastic material and the electrodes are moved toward each other so as to cause the embossing blades to compress the cover sheet and the sheet of filler material into the yieldable material. Sufficient pressure is then applied to the composite sheets to cause the sheet of filler material to be split along the embossing blades to form a plurality of separate strips. This is followed by opening the press and placing a base sheet over the strips of filler material and dielectrically bonding the sheet of thermoplastic material to the base sheet along the trim lines.
