ABSTRACT:
A method and apparatus for supplying dyes to a dyeing apparatus, dyes being selected to yield one of a group of colors. A plurality of tanks of dye is provided, and a circuit leads from each tank to a selected one of a pair of valves that may either direct the dye to the dyeing apparatus or direct the dye to be recirculated. The flow through each valve is metered so a particular rate of flow can be established. One group of the valves provides dye to the dyeing apparatus while another group of the valves recirculates dye to establish another color ready to be provided to the dyeing apparatus. The colors are defined in terms of the tanks and rate of flow from the tanks, so a large group of colors can be defined and stored in a computer, and the computer can control valve position and pump speed to control the color produced by the dyeing apparatus.
