Abstract
Apparatus for developing multi-colored complex patterns in textile carpets formed by a yarn tufting operation, employing a scanner to scan and record color data from replicas or artists' renditions of the patterns to be tufted, a programmable read only memory to store the color data descriptive of the scanned patterns after electronic digitizing of the data, and a microprocessor and logic circuits to select a desired pattern from the memory and provide the color data for the selected pattern to individual yarn control assemblies at spaced dyeing stations of different colors. Individual yarn ends passing through the spaced dye stations are selectively dyed along their length at predetermined positions according to the color data provided to the yarn control assemblies at the spaced dye stations, the yarn ends then being delivered to a tufting machine to produce the selected multi-colored complex pattern. Delivery of color data from memory is controlled by the displacement of the backing applied to the carpet, by means of clocks generated by the backing linear displacement. Delivery of color data to the yarn control assemblies at each dye station, for dyeing of each yarn end at prede…
