Improved apparatus for treatment of relatively moving substrate materials by precise selective application of discrete, high temperature pressurized streams of fluid against the surface of the materials to impart a visual change thereto. The apparatus includes an elongate manifold for receiving pressurized heated fluid, such as air, disposed across the width of the relatively moving material and having a plurality of spaced parallel fluid stream discharge channels for directing the fluid into the surface of the material. Pressurized cool fluid, such as air, is directed into selected manifold discharge channels to block selectively the passage of pressurized heated air therethrough. The manifold is provided with heated air outlets which communicate by passageways with the manifold compartment to continuously bleed off heated air from the manifold, thereby counteracting localized cooling of the manifold adjacent the discharge channels and reducing pressure build up within the manifold when selected of the channels are blocked with the cool air.
In apparatus for treating a relatively moving substrate material by application of discrete streams of pressurized heated fluid to selected surface portions of the substrate to impart a visual effect thereto, and including an elongate fluid distributing manifold positioned across the path of relative movement of the substrate, said manifold defining an elongate fluid receiving compartment and a plurality of fluid discharge outlet channels disposed in parallel spaced relation along the compartment to direct discrete streams of pressurized fluid against the surface of the relatively moving substrate, and means for directing pressurized cool fluid into selected of the heated fluid discharge outlet channels to selectively block the passage of heated fluid therethrough;
