ABSTRACT:
The tufting machine has a pair of elongate needle bars with respective rows of tufting needles thereon extending transversely of the machine and normally forming a single row of aligned needles for serving as one needle bar during each turfting operation, with the needles in one row arranged in alternation with the needles in the other row. The needle bars and needles are so constructed and arranged that the needles in one row are shiftable laterally out of and laterally back into alignment with the needles in the other row. While the needles in one row are out of alignment with the needles in the other row, either or both rows of needles are shiftable longitudinally for changing the order of the needles when the needles are again shifted back into alignment with each other.
