<p>Automotive trim parts in sheet form with thinned marginal and inner areas are fabricated by deforming a felxible sheet to locate selected portions on one side and other portions on the other side of a predetermined line, moving a cutting tool along the line in cutting engagement with the deformed sheet to remove the other portions, and retaining the cut flexible sheet in the deformed state by securing a backing to the areas of the selected portions of the sheet that were on the one side of the line during the movement of the cutting tool. The so fabricated parts can incorporate, as the backing, a relatively heavy insulating or padding layer, such as acoustical plastic foam or other lightweight permeable material, without it being necessary to discard or redesign currently used trim moldings for installation purposes.</p> |
