Abstract
An apparatus for producing randomly or space dyed skeins of yarn and which comprises an open vat adapted to be filled with a liquid dye bath, a rack for supporting a plurality of skeins, and means for selectively lifting the rack such that the rack and skeins may be translated between a fully lowered position in the dye bath and a plurality of raised positions.
Claims13
An apparatus for space dyeing a plurality of skeins of textile yarn for use in fabricating multi-colored tufted carpets and the like, and wherein the skeins have varying color patterns, said apparatus comprising
- an open vat adapted to be substantially filled with a liquid dye bath to define a predetermined liquid level therein,
- rack means for supporting a plurality of skeins of textile yarn in an adjacent, side by side, downwardly hanging arrangement, and
- means for supporting said rack means in a position generally above said vat, and including means for selectively vertically translating said rack means so that said rack means and supported skeins may be selectively translated between a fully lowered position wherein said rack means and supported skeins are completely immersed in the dye bath, and a plurality of raised positions wherein the supported skeins are only partially immersed in the dye bath, said supporting means further including means for selectively tilting said rack means in relation to said liquid level and for maintaining the same in the selected tilted position such that some of the skeins are adapted to be partially immersed in the dye bath further than others when said rack means is positioned at one of said raised positions.
An apparatus for randomly dyeing a plurality of skeins of textile yarn for use in fabricating multi-colored tufted carpets and the like, said apparatus comprising
- an open vat adapted to be substantially filled with a liquid dye bath to define a predetermined liquid level therein,
- a carriage mounted within said vat to define an operative position, said carriage including a plurality of spaced apart, parallel tubes extending in a generally horizontal direction and lying below said liquid level when said carriage is in said operative position,
- a rack comprising a plurality of spaced apart, parallel arms, said arms being arranged to conform to the arrangement of at least a plurality of said tubes on said carriage such that said rack may be positioned above said carriage with each arm immediately overlying one of said tubes and so that each arm and its associated tube is adapted to support a plurality of encircling skeins of textile yarn in an adjacent, side by side, downwardly hanging arrangement, and
- means for supporting said rack in a position generally above said vat, and including means for selectively vertically translating said rack so that said rack and supported skeins may be selectively translated between a fully lowered position wherein said rack is positioned immediately above said carriage and the supported skeins are completely immersed in the dye bath, and a plurality of raised positions wherein the supported skeins are only partially immersed in the dye bath,
- whereby the supported skeins may be dyed with a plurality of colors by repeatedly lifting the skeins an incremental distance out of the dye bath and then changing the color of the dye bath.

- an open vat adapted to be substantially filled with a liquid dye bath to define a predetermined liquid level therein,
- a carriage positioned within said vat, said carriage including a plurality of spaced apart, parallel, hollow tubes extending in a generally horizontal direction and lying below said liquid level, each of said tubes having opening means through the wall thereof,
- means for circulating the liquid dye bath through said vat and carriage, and such that the liquid dye bath flows into said hollow tubes and exits from said opening means therein,
- a rack comprising a plurality of spaced apart, parallel arms, said arms being arranged to conform to the arrangment of at leat a plurality of said tubes on said carriage such that said rack may be positioned above said carriage with each arm immediately overlying one of said tubes and so that each arm and its associated tube is adapted to support a plurality of encircling skeins of textile yarn in an adjacent, side by side, downwardly hanging arrangement, and
- means for supporting said rack in a position generally above said vat, and including means for selectively vertically translating said rack so that said rack and supported skeins may be selectively translated between a fully lowered position wherein said rack is positioned immediately above said carriage and the supported skeins are completely immersed in the dye bath, and a plurality of raised positions wherein said rack is spaced above said carriage and the supported skeins are only partially immersed in the dye bath,
- whereby the supported skeins may be dyed with a plurality of colors by repeatedly lifting the skeins an incremental distance out of the dye bath and then changing the color of the dye bath.
