ABSTRACT:
A method and apparatus for space dyeing a plurality of strands of yarns which are fed over a series of dye applicator rolls. Each roll is rotated in a partly submerged condition in a dye pan containing a different color. Above and offset relative to each dye applicator roll is a yarn pattern roll which carries a number of slats in a circumferential array extending beyond the periphery of the pattern rolls for contacting the yarn strands. The slats sequentially engage and deflect the yarn strands onto the surface of the respective dye applicator rolls. The slats may be positioned in selected slots in the pattern rolls to determine the pattern of color applied to the yarn. Variable speed drives rotate the dye applicator rolls and the pattern rolls independently of each other to effect the spacing of the colors and the amount of dye received by the yarn strands.
