ABSTRACT:
A looper apparatus for a multiple needle tufting machine including a looper support member having a transverse hook bar for supporting a plurality of looper hooks for a cooperation with the reciprocable needles in the tufting machine and an elongated guide member reciprocably supported in linear bearings to restrict the motion of the looper hooks in a straight linear direction substantially parallel to the feeding direction to the base fabric, and a drive mechanism pivotally connected to hook support member for reciprocably driving the support member in a linear path. A stub shaft with thrust bearing is mounted at one end of the tufting machine and connected by a curved rocker arm to an end of the hook bar to offset knife pressure placed against the hooks and communicated to the hook bar.
