ABSTRACT:
A multiple needle tufting machine incorporating a pair of front and rear needle bars each supporting corresponding front and rear needles in transverse rows for simultaneous penetration of a base fabric moving in a feeding direction through the machine. A looper apparatus is provided incorporating a front transverse cut pile hook bar supporting a plurality of cut pile hooks pointing in the direction opposite the feeding direction, and a loop pile hook bar spaced in front of the cut pile hook bar for supporting a plurality of loop pile hooks having bills projecting rearwardly in the feeding direction and opposite the direction of the bills of the cut pile hooks. The looper apparatus further includes a drive and linkage mechanism for simultaneously moving the cut pile hooks and loop pile hooks in opposite directions for cooperation with the corresponding front and rear needles, in order to form loop pile loops behind the cut pile tufts in the same base fabric.
