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.

Claims

1. A hook module for use in a tufting machine comprising, a cast metal body member, a plurality of tufting machine hooks, each hook having a shank including a mounting portion at one end, a blade extending from the shank to define a throat therebetween and terminating at a bill remote from said mounting portion, the mounting portions of said shanks being molded into said body member in spaced side-by-side disposition and extending through said body member with the ends of the mounting portions being visible at a surface of the body member remote from the bills, and retaining means formed on the mounting portions for securely retaining said hooks in the body member.

2. A hook module as recited in claim 1, wherein said hooks comprise tungsten carbide.

3. A hook module as recited in claim 1, wherein said retaining means comprises a detent in an edge of said mounting portion.

4. A hook module as recited in claim 3, wherein said hooks comprise tungsten carbide.

5. A hook module as recited in claim 1, wherein a portion of said shank in addition to said mounting portion is molded into said body member.

6. A hook module as recited in claim 5, wherein said hooks comprise tungsten carbide.

7. A hook module as recited in claim 6, wherein said retaining means comprises a detent in an edge of said mounting portion.

8. A hook module as recited in claim 1, wherein said body member has a datum surface remote from said bills, said datum surface having a lip extending therefrom and terminating in a rear surface beyond said datum surface removed from said bills, the ends of said mounting portions extending to said rear surface.

9. A hook module as recited in claim 8, wherein said hooks comprise tungsten carbide.

10. A hook module as recited in claim 9, wherein said retaining means comprises a detent in an edge of said mounting portion.

11. A hook module as recited in claim 10, wherein a portion of said shank in addition to said mounting portion is molded into said body member.
