  • Patent number: 5184446
    Abstract: A unique platform performs several functions in the installation of planar flooring. The platform has a planar top face and a pair of wheel sets on an underface. In a first function the platforms are used in groups of two, and positioned with the wheels extending upwardly and spaced from each other such that the axis of rotations of the sets of wheels on the two platforms are generally parallel and aligned. A coil of planar flooring material is placed on the spaced platforms, such that the planar flooring material may be removed from the coil with the wheels turning to aid in the removal and protect the surface of the flooring. After the planar material is removed and has been adhesively applied to a floor, the platforms perform a second function. They are reversed and a force is applied to the platform such that the wheels roll along the planar flooring and cause the adhesive to wet and firmly secure the planar flooring to the underlying floor.
