  • Patent number: RE36458
    Abstract: Vinyl heat welding rod for seam sealing vinyl resilient flooring, whether in sheet or tile form, are used to obtain a homogeneous, monolithic appearing surface. This rod is specifically made to duplicate the appearance of the flooring material. For a chip-image flooring structure, a sheet of multicolored chips having a similar, but different formulation from that of the flooring material is prepared and the sheet is cut into suitable strips, heat pressed in a rod mold, end adhered or further molded to form the desired length, and used as a vinyl heat welding rod for sealing seams in flooring. Thus, the chip pattern is evident in the seam area and does not appear different when compared to the adjacent surface.
