Apparatus for dyeing and printing materials

In apparatus for applying dye to a moving material to print a pattern thereon, including means for moving the material in a path of treatment, at least one elongate dye jet gun bar having a plurality of dyeemitting jet orifices positioned along the bar for directing the dye in plural streams onto the material, and support means having support elements positioned on the sides of the path of material treatment for positioning the gun bar across the path;

• the improvement wherein said gun bar comprises an elongate structural support plate extending across the path of material treatment, means attaching the support plate to said support elements for support thereby, means attached to one elongate edge of said plate for imparting structural stability thereto, an elongate dye manifold pipe having an inlet for receiving dye for distribution and a plurality of dye outlets spaced along its length, means securing the dye manifold pipe along the other elongate edge of said plate for support thereby, an elongate dye applicator section for dispensing dye in plural streams onto the moving material, and means securing said dye applicator section to said manifold pipe for support thereby with the section extending along the length of the manifold pipe and across the path of material treatment, said applicator section including dye receiving chamber means and a plurality of passageways connecting said chamber means with said dye outlets of said manifold pipe, and a plurality of channels in said applicator section communicating said chamber means with outlets forming said plurality of jet orifices for emitting dye onto the moving material.
