ABSTRACT:
An automotive vehicle headliner is formed from a flat strip having laminated layers of resilient, cellular, foamed plastic and a finish textile material. The strip is cut to form a flat blank which is heated to a temperature at which the foamed plastic loses its resilience. While in its heated state the blank is compressively deformed and simultaneously trimmed in a mold to the desired size and contour and the cells adjacent the marginal edge of the blank are reduced in size to reduce the wall thickness of the blank. The deformed and trimmed blank is cooled while the compressive air force is maintained.
