Abstract
An automotive trim strip laminate formed of a thin strip of polyester material bearing a layer of metallic material and bonded to a substrate of a polyvinyl chloride material is made so that the laminate can be thermally bonded to a support material along a curved path without any wrinkling or other irregularity. This is done by longitudinally tensioning the laminate after it has cooled below its annealing temperature following extrusion of the substrate to strain the laminate sufficiently so that it tends to shorten upon reheating to its annealing temperature. The strain is insufficient to cause strain-relief shortening of the laminate at ambient temperatures encountered during storage and transport but is sufficient so that when the strained laminate is held accurately to the curved path and thermally bonded to the support material, its thermal expansion cooperates with strain relief to bring the laminate into smooth and uniform conformity with the curved path.
