ABSTRACT:
A method and apparatus for applying a random, speckled pattern of dye to a moving web, such as carpeting. A series of closely spaced distributor units are mounted over the top surface of the web, and each carries a rotating disc, onto which dye material is flowed at a controlled rate. The rotating discs are formed with a highly irregular peripheral contour, such that a high degree of variability and randomness is imparted to the size and trajectory of the atomized dye particles. A significantly improved appearance of randomness in the speckled pattern is achieved.
