Abstract
Abstract A mechanical, spring clip mounting method for plastic trim strips allows plastic to be substituted for metal in trimming automobiles. A base lamina of plastic is formed and punched with holes through which spring clips are inserted, and trim lamina is secured to the base lamina to cover the spring clips which are pressed into holes to fasten the trim strip in place.
