ABSTRACT:
A yarn feed mechanism for a tufting machine includes yarn feed rolls disposed along parallel axes transversely adjacent to the parallel paths of travel of yarns from yarn sources to the needles. A yarn control assembly surrounds each roll, each yarn control assembly having a pair of opposed, concentrically mounted, indexing plates at opposite ends of each roll. Each pair of indexing plates carries a plurality of individually removable cimcumferentially spaced, yarn control rods, the plates being manually rotatable about the axis of the roll, independently of the rotation of the roll. By collecting intermediate increments of selected yarns on one of the rods, then rotating the indexing plates, with the rod installed to selected positions, the rod is moved in an orbital path for applying the yarn increments to portions of the periphery of the roll, such that the roll feeds controlled successive amounts of applied yarns toward the needles.
