  • at least one reciprocating needle bar carrying a series of spaced needles;

    backing feed rolls for feeding a backing material through the tufting machine;

    a series of servo-motor driven yarn feed devices, each including a servo-motor and a feed roll driven thereby,wherein a majority of the yarn feed devices receive at least two yarns per feed roll and feed each of the yarns to selected ones of the needles so as to form at least two pattern repeats across the backing material, andwherein there are approximately one-half the number of yarn feed devices as there are needles of the tufting machine; and
