ABSTRACT:
A tufting machine having a pair of rows of spaced apart needles which are independently selectively reciprocated in a path toward and away from a base material fed in a direction longitudinally from one row to the other through the machine. The machine includes drive mechanism including push rods which reciprocate during each cycle. A yoke is secured to each push rod and has a pair of downwardly depending limbs spaced apart longitudinally and corresponding to a respective row. The limbs for each row carry an air cylinder latching bar including latches which are controlled in accordance with a pattern. The needles are each carried by a respective needle holder mounted between the limbs and each needle holder may be coupled to the latch bar corresponding to that row selectively. Each needle in one row may be paired with a corresponding needle in another row aligned laterally across the machine and both needles in a pair may cooperate with a single looper, or the needles in one row may be laterally offset from the needles in the other row and each needle cooperates with one looper.
