A needle bar assembly for a multiple needle tufting machine including an elongated continuous mounting bar connected to the push rod of the needle drive mechanism for reciprocal movement, and a plurality of elongated, but substantially shorter, needle bar segments having needle holes for receiving the needles and secured end-to-end along and to the mounting bar, whereby individual needle bar segments may be independently attached and detached to the mounting bar, and longitudinally adjusted if desired. The needle bar assembly also contemplates a pair of needle mounting bars slideably received in a needle bar holder connected to the needle drive mechanism and two sets of substantially shorter needle bar segments secured end-to-end along each of the corresponding needle mounting bars.
