A conventional tufting machine is provided with front and rear juxtaposed, laterally shiftable, needle bars positioned on a common needle bar support. A first series of needles having a first take-off hand, in a first gauge, are embedded in a first needle gauge block mounted on the front needle bar. A second series of needles of an opposite take-off hand, in a second gauge, are embedded in a second needle gauge block fastened to the rear needle bar. The needles of the first and second series of needles, respectively, combine together to form a third series of needles of a desired gauge of the machine, the gauge of the machine being narrower than the gauge of either the first or second series of needles, respectively. A looper gauge block is positioned with respect to the needle gauge blocks, the looper gauge block having a first and a second series of spaced and parallel loopers embedded therein, each looper of the second series of loopers being paired with an adjacent one of the loopers of the first series of loopers to form spaced pairs of loopers extending along the length of the looper gauge block. The loopers within each pair of loopers have a take-off hand corresponding to that of the needle the looper will engage, and the take-off hands within each pair of loopers are opposed to one another. The loopers within each pair of loopers are spaced apart a first distance, and each of the pairs of loopers are spaced apart from one another a second distance greater than the first distance.
