Abstract
A cut pile tufting machine having needle plate backing support fingers oscillated in timed relationship with the hooks and the needles 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 has the bill of the hooks reduced in thickness on a portion thereof. The bill has a lower or cutting edge and an upper edge, and the portion of reduced thickness is provided by narrowing the upper edge relative to the lower edge along that portion of the bill on which a loop seized by the hook is drawn against and cut.
