A tufting machine of the type having laterally shiftable front and back needle bars carrying transverse rows of needles disposed adjacent to a backing material for reciprocation by said needle bars toward and away from said backing material, for sewing successive transverse rows of loops of yarns in said backing materials, yarn feed controls for yarns of the needles of each of said needle bars for feeding successive prescribed lengths of yarns to certain of said needles to produce either high or low loops thereby forming tufts in said backing material, needle bar shift controls for shifting said needle bars, and a plurality of electrical feed control members in said yarn feed controls for respectively controlling the feeding of said yarns to said needles;

  • the improvement comprising;

    (a) computer means for providing signals for actuating said electrical feed control members;

    (b) means for synchronizing the operation of said shift controls with signals for actuating said electrical feed control members; and

    (c) said computer means supplying signals to said electrical feed controls and to said shift control members for producing diagonal rows of high and low tufts in said backing material using certain yarns and wherein the low tufts of said certain yarns are hidden from view by the high tufts of certain other yarns in said backing material.
