Abstract
Abstract A pattern is applied to a travelling web, such as a rug, by delivering a carrier liquid with individually spaced apart quantities of a pattern liquid therein to the surface of the rug. The pattern liquid is delivered into or onto the carrier liquid via various types of applicator means and the individual quantities of pattern liquid are maintained in spaced apart relation at least until being deposited onto the nap of the rug.
