ABSTRACT:
A hook module for use in a tufting machine has a molded body member including a plurality of tufting machine hooks cast therein in side-by-side relationship. The hooks have a bill at one end, a blade extending from the bill to a shank and a mounting portion of the shank extending remote from the bill. The mounting portions of the shanks extend to the rear surface of the body member so as to prevent divergence of the bills after the body member has been cast about the mounting portions and adjacent portions of the shanks. The hooks are constructed from tungsten carbide which precludes their bending to provide the requisite parallelism of the bills as is possible with bendable hooks in prior art modules not requiring the mounting portions to extend to the rear surface.
