Abstract
An improved tufting machine with a precision drive system for laterally shifting the reciprocating needle bars of the tufting machine across a tufting zone in which tufts of yarn are made in a backing material advanced through the machine beneath the needle bars is disclosed. The precision drive system includes the use of inverse roller screw actuators which may be adapted for driving the several moving components of the tufting machine, to include not only the shifting of the needle bars, but also can be used to reciprocate the needle bars toward and away from the tufting zone, rock the loopers and or knives of the machine, and to shift the backing material in which the tufts of yarn are made as it advances through the tufting machine.
