  • Patent number: 4655784
    Abstract: A method of sequentially coloring individual, precut, backed carpet tiles comprising moving an individual, precut, backed carpet tile into overlying spaced relationship with a tuft dye mold of substantially the same size as the carpet tile, with the tuft dye mold having a plurality of dye mold sections therein separated from one another by a vertical divider walls within the tuft dye mold. The tufted side of the carpet tile is brought into engagement with the tuft dye mold which has predetermined amounts of fluid colorant in any one or more desired sections thereon for imparting color to a portion of the carpet tile corresponding to said section or sections. A predetermined amount of pressure is exerted on the carpet tile on the tuft dye mold and on the fluid colorant therein and thereby minimizes the migration of colorant from one portion of the carpet tile to another portion while thoroughly impregnating each of said predetermined portions with said fluid colorants.
