This disclosure relates to a method and apparatus for forming patterned cut pile tufted fabrics and, in particular, colored patterned tufted pile fabrics. The patterns are essentially produced by selectively backrobbing one leg of a cut loop thereby producing a cut loop having one relatively long leg and one relatively short leg. By selectively backrobbing one leg of a cut loop of one color yarn and by refraining from backrobbing a leg of a cut loop of at least a second color, the second color will become predominant in the pattern by virtue of having twice as many long legs of that color making up the surface of the cut pile tufted fabric. The disclosure also encompasses a method and apparatus for producing relatively long nap cut pile tufted fabrics having controlled J-cut loops.
