A tufting machine which employs at least one row of tufting needles and a pin roll in the needle plate to control transverse movement of the backing material. The pin roll impales the incoming backing material to be tufted and is shifted laterally one-half gauge for each reciprocation of the needle bar to eliminate the roving effect of the tufted yarn in the tufted fabric being produced.
