Claim 6:
7. A tufting machine for forming a series of tufts of yarns in a backing in accordance with a pattern, the tufting machine comprising:
a series of spaced needles mounted along one or more needle bars, the needles carrying the yarns into and out of the backing;
a series of gauge parts arranged below the backing and reciprocable toward the needles as the needles are reciprocated into the backing, the gauge parts configured to pick loops of yarns from at least some of the needles; and
a rack and pinion shift control assembly coupled to at least one needle bar of the one or more needle bars and comprising a rack, a pair of pinions each configured to engage the rack at multiple points of contact therealong, and at least one motor connected to at least one pinion of the pair of pinions for driving rotation of the at least one pinion;
wherein as the at least one pinion is rotated, the rack is driven linearly so as shift the needles transversely across the backing.
