the branch pipe 7 divided from the supply pipe 4 the dye liquid is sprayed through the spray orifices 5 in the spindles 6 connected with the distributing means 9 joined to the branch pipe 7 onto the yarn hanks 14 supported on the spindles in bath 1 39 and rotated thereby due to the rotation of the spindles by spraying the dye liquid through the spray orifices 5 the yarn hanks in the bath 1 39 are dyed in the above example the bath 1 is operated for dipping and the bath 1 39 is operated for spraying it will be understood that this may be reversed such that bath 1 39 is operated for dipping while bath 1 is operated for spraying by supplying dye liquid through pipe 4 39 rather than pipe 4 the temperature of the dye liquid supplied from the pump is not normally that desired to dye the yarn hanks in the baths however by increasing slowly the temperature of the dye liquid by the heaters 13 in the baths and by alternately circulating the supply of the heated dye liquid into the baths 1 and 1 39 repeatedly good dyeing quality can be accomplished after a certain period of time during a dyeing operation the supply of the dye liquid to the baths 1 and 1 39 is exchanged by changing the positions of the valves 8 and 8 39 this allows counter flow of the dye liquid through the pump 3 and the dyeing operations in each bath.
