A substrate object (20), such as a concrete block, has a protective and decorative composite film element (30) applied thereto. The composite film element (30) may comprise a bottom layer of heat reactive adhesive (62); an intermediate strong stable carrier layer (60); a decorative layer containing coloration or designs (64); and a protective exterior layer (66). The composite film element (30) is applied by preheating the substrate object (20), selectively heating the surface of the substrate object (20) to which the element (30) is to be applied to a predetermined temperature; positioning the composite film element (30) on the heated portions of the substrate object (20); applying even pressure to press the composite film (30) against a surface of the substrate (20) and to fold the edges of the composite film (30) against the sides of the substrate (20) adjacent to the surface; and thereafter cooling the substrate (20). The process and apparatus (800) for applying the composite film element (30) may employ the air used to cool the substrate objects (20) to preheat subsequent substrate objects (30) to provide energy efficient cooling abd counterflow preheating steps. |
