ABSTRACT:
A tufting machine has a hook bar for mounting a plurality of hooks and is secured to a plurality of drive links driven by oscillating rocker arms from a rock shaft, and includes a plurality of resilient leaf springs secured at spaced apart locations to the hook bar and to a fixed member in the bed of the tufting machine. The leaf springs provide a low oscillating mass support for the hook bar in the plane of oscillation. Tension tie-rods extend laterally between adjacent drive links to counteract the lateral loads of the knives against the hooks.
