  • Patent number: 4748706
    Abstract: A method and apparatus for sequentially performing dye strikes on a continuous dye range from a plurality of dye lots to reduce downtime of the range. The apparatus employs two dye pans that are horizontally and vertically movable relative to the dye pad on the range so that each can be sequentially moved into and out of a dyeing position while the machine is running and fabric continues to move therethrough. The textile material includes a leader section ahead of the fabric to be dyed in a desired strike order, such as, for example comprised of three leaders with first and second dye strike patches positioned therebetween in order to provide first and second strikes or runs on a continuous basis without stopping the dye range.
