  • Patent number: 5655574
    Abstract: Streakless appearing woven rugs incorporating large uninterrupted areas of a single color are formed by at least two ends of yarn of the same color alternating in the face of the rug along each of the longitudinal rows in the uninterrupted area. The two ends of yarn may alternate in an ordered or random pattern, and suitably may alternate at least every twelve inches.

  • Patent number: 5538047
    Abstract: A process by which rugs and other pile fabrics can be woven to incorporate large uninterupted areas of a single color without a streaking appearance. As a fabric is being woven and a yarn end is woven into the face of a fabric, before the distance of the yarn end on the face of the fabric reaches a significant length, the yarn end is pulled from the face of the rug to float on the back of the rug as the weaving process continues. Meanwhile another end of identical color takes the place of the floating yarn end, and is woven into the face of the rug along the same longitudinal row, also for no more than a significant length. By this technique an off-color yarn will not travel far enough in a continuous line to manifest itself to the human eye as a streak. By pulling the same color yarn from two creel positions in every longitudinal row of a single colored area, and alternating between the two positions in every longitudinal row streaks do no appear in any part of the rug.
