This provides for a coloring of the carpet with the dye. The improvement herein is in the recirculation of the dye in the manifold to maintain the particles in the dye in suspension, and further, to interrupt the flow of dye from the nozzles to the plate to better distribute dye particles on the plate for subsequent distribution to the carpet.

Abstract: A method and apparatus for treating textile materials, such as carpet, employs an applicator station having a number of spray jets for causing a plurality of streams of fluid to be fanned out into a corresponding plurality of fan shape sheets of spray directed to the surface of a roller. The spray jets are used to spray either air, dye or gum. The roller is mounted for rotation in a dye or gum trough and the jets spray air or other fluid to cause a pattern to be formed in the dye or gum film on the roller. The pattern is transferred to the face of the carpet by a doctor blade or, alternately, directly to the carpet face. The trough may be filled with gum in which case the jets spray dye onto the film of gum picked up by the roller. The trough may also be used for dyeing in which case a different color dye is applied by the jets or multiple roll applicator stations may be provided for multi-color and tone effects. Alternately, no trough is used and dye or gum may be applied by the spray jets to the roller.

Abstract: A method and apparatus used in the uniform drying of a continuous web, such as a sheet of paper or paperboard. A newly formed web of paper of wet cellulosic fibers and the necessary additives is initially directed through a press section where excessive water is squeezed from the web to reduce its moisture content to about 50-80 percent, by weight, for subsequent passage through a dryer section wherein the moisture content is further reduced to anywhere between 3 and 15 percent, depending on the quality of the paper being processed.
