Abstract
A process of making backed, pressure-adherent carpeting. A construction is assembled comprising a backing-film and an adhesive on one side of the backing film, and then, in a separate step, the other side of the backing film is heat-laminated to a web of carpeting to thereby reinforce the carpeting and provide it with an adhesive. The carpeting is both reinforced and rendered adherent in a single pass of the carpeting and at a single station in the carpet-manufacturing line.
