A tufting needle assembly for use with a tufting machine is disclosed. The tufting needle assembly comprises a first gauge block or needle bar having a first series of tufting needles disposed thereon. The respective tufting needles are spaced from one another along a first longitudinal axis extending in the lengthwise direction of the gauge block. At least one tufting needle is offset with respect to the first longitudinal axis and the adjacent ones of the tufting needles in the series of tufting needles in the range of from 0.005 to 0.100 inches. A shank of the at least one tufting needle may be offset with respect to the first longitudinal axis and those of the adjacent tufting needles, or alternately the shank may be aligned with those of the adjacent tufting needles and a needle tip of the at least one tufting needle is offset with respect to the first longitudinal axis and the needle tips of the adjacent ones of the tufting needles in series. The tufting needle assembly further comprises a second series of spaced tufting needles disposed either on the first gauge block or a second gauge block, the tufting needles within the second series extending along a second longitudinal axis spaced parallel to the first longitudinal axis in the range of from 0.20 to 0.25 inches. The respective tufting needles within the second series may be aligned with respect to one another and extend linearly along the second longitudinal axis, or alternately at least one tufting needle of the second series may be offset with respect to the second longitudinal axis and the adjacent ones of the tufting needles within the second series.
A tufting needle assembly for use with a tufting machine, the tufting machine having a frame, at least one elongate and reciprocating needle bar supported on the frame and adapted for a lateral shifting motion with respect to the frame, and a series of loopers of a predetermined tufting machine gauge, one series of loopers for each needle bar, positioned with respect to the needle bar, said tufting needle assembly comprising:
