A machine dyeing reels of yarn and textile fibers wound on packages, including: a structure delimiting a chamber partially or fully filled with a dyeing fluid; a support immersed in the dyeing fluid; a plurality of reel-holder rods that communicate via the fluid with the support to allow the dyeing fluid to pass the support; first and second recirculation mechanisms associated with the structure, to initiate transit of the dyeing fluid in accordance with at least one set route. The first recirculation mechanism interposed between the chamber and the support induces the dyeing fluid to pass through the reel-holder rods and includes a pump and respective selection mechanisms to intermittently channel the dyeing fluid through the support, the reel-holder rods, and the respective reels. The second recirculation mechanism induces transit of the dyeing fluid within the chamber in accordance with at least one closed route.

MACHINE AND PROCEDURE FOR THE DYEING OF REELS OF YARN AND/OR TEXTILE FIBRES WOUND ON PACKAGES
This invention relates to a machine (1) for the dyeing of reels of yarn (8) and of textile fibres wound on packages. The machine (1) comprises: a structure (2) that delimits a chamber (3) at least partially or fully filled with at least a dyeing fluid (4); support means (6), in particular at least one support plate (6), immersed in the dyeing fluid (4); a plurality of reel- holder rods (7) that communicate via the fluid with the support means (6) to allow the dyeing fluid (4) to pass between the latter; recirculation means (9) for the dyeing fluid (4) associated with the structure (2) to initiate the transit of the dyeing fluid (4) in accordance with at least one set route. The recirculation means (9) comprise an initial recirculation mechanism (10) interposed between the chamber (3) and the support plate (6) to induce the dyeing fluid (4) to pass through the reel-holder rods (7). The first recirculation mechanism (10) comprises a pump (10a) and respective selection mechanisms (12) to channel the dyeing fluid through the support means (6), the reel-holder rods (7) and the respective reels (8), on an intermittent basis. The recirculation means (9) comprise a second recirculation mechanism (11), to induce the transit of the dyeing fluid (4) within the chamber (3) in accordance with at least one closed route.
