Bristled Or Tufted Article Making Patents (Class 264/243)
  • Patent number: 3959434
    Abstract: A three dimensional, decorative material is disclosed and claimed herein, having good dimensional definition and capable of virtually unlimited design. A process for producing the three dimensional composite is also disclosed and claimed herein. The process originates with the manufacture of a master mold which can be produced with virtually any design, and preferably is made into a continuous belt. An elastomeric foam composition is then cast into the cavities of the master mold and fused in situ, whereby a three dimensional material is produced. Thereafter, a suitable adhesive is applied to the design side of the material and flock fibers or some other decorative substances are deposited thereon. After curing of the adhesive, any excess fibers are removed, and the material may be cut into suitable lengths, provided with a contact adhesive on the reverse side or the like.
