  • Thermal forming upholstery process
    Patent number: 5935364
    Abstract: A method for forming upholstered articles involves providing an upholstery fabric having a tensionable drawstring, positioning the upholstery fabric over a front side of an article which is to be upholstered, folding the periphery of the fabric upholstery over edges of the article, applying tension to opposing ends of the drawstring, and securing the ends of the drawstring to the back side of the article to form a preassembled upholstered article. The fabric on the preassembled upholstered article can be adjusted, such as to remove wrinkles. Thereafter, heat can be applied to the preassembled upholstered article to activate thermally activable adhesive disposed between the article and the upholstery fabric to cause the upholstery fabric to be permanently adhered to the article.
