Abstract
A tufting machine and method of tufting on a backing fabric, where the machine for carrying out the method includes a needle push bar, loopers, a needle selector for selecting certain ones of the needles at every needle stroke cycle and for inserting the selected needles into the backing fabric, a feeder for intermittently and longitudinally feeding the backing fabric in a stop and feed manner, a shifter and a pattern controller. The backing fabric remains stationary in the longitudinal direction during a stopping period which is at least one needle stroke cycle in duration and may be fed during a succeeding feeding stroke period. The shifter aligns selected ones of the needles each with any one of an associated plurality of the loopers by effecting relative lateral shifting movement between the needle push bar and both the loopers and the backing fabric while the backing fabric remains stationary in the longitudinal direction during the stopping period. The pattern controller actuates the needle selector to select any one of the needles for insertion into the backing fabric and tufts with the pile yarn carried by the selected one of the needles by engagement with a corresponding o…
