Abstract
A knife mounting block for a tufting machine is formed with a pair of reference surfaces one of which forms the angle of inclination and the other forms the angle of canter that the knives make with the tufting machine hooks, the reference surfaces cooperating with corresponding surfaces of the tufting machine knife bar. One of the reference surfaces includes a slot which receives a pin extending from the knife bar so as to determine the gauge between respective knife blocks. Positioning of the knife blocks on the bar will engage the pin within the slots and accurately gauge the blocks and thus the knives at the proper gauge. The knife bar may include a slidable member from which the gauging pins extend so that the pins can be adjusted to match the gauge of the hooks and compensate for accumulative gauging tolerances of the needle bar of the tufting machine. The knife blocks can thus be removed from the tufting machine and returned to the exact position when required.
