  • Patent number: 7803727
    Abstract: A vinyl floor covering is provided with reinforcement of segmented woven or non-woven glass fiber mat located on the underside of the vinyl floor covering or at or near the neutral axis of the vinyl floor covering. This segmented mat reinforcement increases the stiffness and mechanical properties of the vinyl floor covering. A polymeric binder separates the segments of the glass fiber mat from each other. Expansion or contraction of the installed vinyl floor covering is restricted to this polymeric binder region. The segments may be aligned with the vinyl floor covering's show surface patterns, thereby preserving pattern integrity. The segmented mat is manufactured by applying and curing a polymeric binder to a woven or non-woven glass fiber mat, and creating segments by the passing the woven or non-woven glass fiber mat with polymeric binder through a set of embossing rollers. The segmented woven or non-woven glass fiber mat with polymeric binder is easily handled by vinyl floor covering machinery.
