Abstract
A method of making a floor covering including a tufted textile substrate and a reinforcement backing system. The backing system includes adhesive layers which are conditioned to include voids. A layer of reinforcement fibers is positioned between the adhesive layers. After drying, the layers of adhesive and reinforcement fibers are compressed to collapse the voids in the layers of adhesive and to encapsulate the reinforcement fibers. The layer of reinforcement fibers is also moved toward the primary backing substrate and into engagement with the ends of the tufts.
