Abstract

A cut pile tufting machine having needle plate backing support fingers oscillated in timed relationship with the hooks and the needles of the machine to support the backing material during needle penetration and to withdraw from the needle path as the hooks move across the needle path to seize loops. The needle plate is mounted on a rocker arm carried by a common rock shaft with the rocker arm on which the hooks are mounted so that the needle plate together with the fingers oscillate in opposition to the oscillation of the hooks. As the hooks move toward the needle center line the fingers move away and as the hooks move away from the needle center the fingers move toward the needle center line.
