ABSTRACT:
Multiple strands of undyed yarn are fed continuously from supply spools or bobbins supported on a creel to a skein winding apparatus. The strands each pass along a substantially horizontal path through one or more spaced dyeing stations where they are engaged by an oscillating frame and caused to oscillate laterally back and forth from said paths while streams of dye individual to the yarns are continuously directed onto the yarns from a series of overhead tubes at the dyeing stations. The strands thus periodically interrupt the dye stream of the associated tubes and receive dye at a multiplicity of spaced portions along their lengths with intervening portions of the yarns remaining uncolored. The space dyeing can be varied by changing the speed of movement of the yarns, by varying the amplitude and speed of movement of yarn guide means which produces the lateral oscillation of the yarns and by selectively operating varying numbers of dye stream feeders at one or both dyeing stations. Upon completion of the space dyeing operation, the individual skeins of yarn can be batch dyed in an overcolor.
