Abstract: A primary backing is needle punched with fiber strands to form a tufted carpet. The short loops of the strands which the tufting needle formed on the primary backing are treated with a solvent which softens the outer surface of the fibers. A secondary backing is then applied over the primary backing, and a sandwichlike structure is formed with the primary backing and secondary backing having therebetween the short fiber loops which have been softened by the solvent. After the solvent has been vaporized, the two backings are adhered to each other and the fiber loops. Adherence is due primarily to the fact that the fiber loops had been softened by the solvent and turned into an adhesive which, upon drying, serves to bond the elements together.

Abstract: An apparatus is provided for making carpet tiles. Large pieces of carpeting material are fed through a series of carpet cutters to form one-square-foot carpet tiles. A large piece of carpeting or a carpet slug is automatically fed onto a conveyor structure and passed by several carpet cutters which cut the carpet slug into a plurality of one-square-foot carpet tiles. Carpet is conveyed on a needle bed support structure with the carpet face against the needles of the needle bed so that the carpet cutters will cut on the back surface of the carpet.
