Oxidation intensifier for continuous warp-chain indigo dyeing machines

An oxidation intensifier apparatus for continuous warp-chain indigo dyeing machines having at least two spaced dyeing and squeezing units for dyeing a plurality of adjacent spaced parallel warp threads passing in a traveling path through said at least two spaced dyeing and squeezing units, said apparatus comprising:

• a first oxidation intensifier unit mounted on one side of said traveling path;
• a second oxidation intensifier unit mounted on the opposite side of said traveling path from said first oxidation intensifier unit;
• each oxidation intensifier unit being disposed between said at least two spaced dyeing and squeezing units and comprising:
• a diffuser having a diffuser inlet and a diffuser outlet, said diffuser outlet being in spaced relationship to said traveling path of said warp threads and having a width extending the entire width of said warp threads transverse to the direction of travel of said warp threads in said traveling path and a length extending longitudinally in the direction of travel of said traveling path of said warp threads for a predetermined distance,
• at least one fan means having an inlet side and an outlet side, said outlet side being disposed adjacent to said diffuser inlet;
• and
• said diffuser outlets of said first and second oxidation intensifier units being spaced substantially equidistantly from said warp threads on opposite sides of said traveling path of said warp threads, so that operation of said at least one fan means of each intensifier unit draws air through said fan input side and expels air through said output side and through said diffuser inlet into and through said diffuser for uniform distribution of said air onto opposite of sides of warp threads moving in said traveling path.
