Abstract
A method and apparatus for forming high accent pile loops at spaced intervals in a tufted pile fabric. The apparatus for carrying out this method includes separate yarn feed rolls for being selectively driven at a high speed, a low speed, and a minimal speed, by a pattern control mechanism for selectively forming regular high pile loops and low pile loops and also for braking the loops in a single row in order to produce sequentially pile loops of minimal height followed immediately by accent pile loops of heights at least as great as the regular high pile loops, and then by additional minimal height pile loops.
