ABSTRACT:
At least two differently colored yarns are delivered by feed rollers through yarn guides under control by a single or double lobe cam between the yarns to a needle bar which carries the two ends per needle and inserts same through a primary backing fabric which is caused to zigzag to create a varigated or tweed-looking tufted pattern. The feed rollers and cam are controlled by separate variable sheaves. The method is characterized by the separation of two differently colored yarns to one needle and the control of the two yarns by a cam and sheave drive while moving the backing material laterally or transversely beneath the needles.
