  • Preseamed sheet flooring product
    Patent number: 6699554
    Abstract: A preseamed, resilient sheet flooring including first and second composite sheet products positioned closely adjacent each other edge-to-edge to form a seam therebetween. An adhesive is positioned in the seam. The adhesive extends completely through the thickness of the sheet flooring, bonds with the first and second sheet products through the entire thickness thereof, and has visual characteristics suitable for creating an indistinct appearance of the seam in the sheet flooring product. The adhesive also has wear characteristics sufficiently similar to wear characteristics of the sheet flooring to maintain the visually indistinct appearance of the adhesive on the surface of the seam as wear occurs to the sheet flooring, thereby creating a finished seam sufficiently strong and flexible to permit the adhesive to be positioned in the seam prior to unrolling the flooring onto a subfloor surface.
    Type: Grant

  • Preseamed sheet flooring method
    Patent number: 6582550
    Abstract: A preseamed sheet flooring product having first and second sheet products positioned closely adjacent each other edge-to-edge to form a seam therebetween. An adhesive is positioned in the seam and has visual characteristics suitable for creating an indistinct appearance of the seam in the sheet flooring product. The seam also has wear characteristics sufficiently similar to wear characteristics of the sheet flooring product to maintain the visually indistinct appearance of the adhesive on the surface of the seam as wear occurs to the end product sheet material.
