Abstract: A jet applicator for a multi-color type foam dyeing machine is disclosed. The applicator provides multi-color foams with a constant gap and uniform state between the color foam dyes for dyeing woven stuff. For forming the foam dyes in a wavy pattern, the applicator comprises foam discharging tubes inserted in holes formed on a lower portion of a rectangular type frame member, an inclined plate and a cylindrical roll provided beneath the frame member, and guide blades fixedly disposed to a movable traversing rod. Therefore, the woven stuff supplied at a constant rate can be dyed over a wide range of various colorful patterns and designs.
