Apparatus for dyeing and printing materials having improved dye recirculation means

In apparatus for applying dye to a moving material including means for moving a material to be dyed in a path of treatment, at least one elongate dye jet gun bar positioned adjacent the path and having a row of dye-emitting orifices spaced along the bar for directing dye in plural streams onto the material, means positioned to one side of said row of orifices for selectively deflecting one or more of the dye streams emitted by the orifices away from the path of material treatment, and a dye collection trough positioned along the other side of said row of orifices and having an elongate opening extending along the row of orifices adjacent thereto for receiving the deflected dye from said plural streams therein;

• the improvement wherein said dye collection trough includes an elongate movable plate having an elongate edge defining the elongate boundary of said opening which is remote from said dye-emitting orifices, and camming means mounting said plate to said trough for sliding movement along said collection trough to variably position the edge of the plate relative to the dye orifices and dye streams directed therefrom, whereby collection of dye deflected from said streams is facilitated.
