Abstract

A cut/loop tufting machine looper/clip assembly wherein a pair of body members respectively support a plurality of loopers or clips. The body members have complimentary reference surfaces for co-operative mating engagement of the members and for engagement of a flag on the clip resiliently with the nose of the looper as required for tufting cut pile and loop pile selectively. The body members are secured together to form a modular unit for installation in the tufting machine.

Claims

1. A modular assembly for supporting loopers and spring clips adapted for mounting in a tufting machine for producing cut and loop pile selectively, said assembly comprising, a plurality of loopers, each looper having a shank including a mounting portion at one end and a bill extending therefrom terminating in a nose, a first body member, said first body member having means for receiving and securing the mounting portion of said loopers in spaced side-by-side disposition, a plurality of spring clips, there being one clip for each looper, said clips having a shank including a mounting portion at one end and extending toward an offset flag, a second body member, said second body member having means for receiving and securing the mounting portions of said spring clips in spaced side-by-side disposition, the spacing between adjacent clips being substantially the same as the spacing between adjacent loopers, said first and second body members having means defining complementary reference surfaces disposed relative to the disposition of said loopers and said clips for co-operative engagement of said body members and for engagement of each flag resiliently with the nose of a respective looper, and means for securing said body members together as a unit in co-operative engagement.

2. A modular assembly as recited in claim 1 wherein said complementary reference surfaces each comprise a pair of planar surfaces joined at a step in the respective body member.

3. A modular assembly as recited in claim 1 wherein the reference surface of said first body member is disposed on the bottom thereof and said reference surface of said second body member is disposed on the top thereof, whereby said first body member is positioned on the second body member, said flag being disposed on said clip above the clip mounting portion.

4. A modular assembly as recited in claim 3 wherein said reference surfaces include a respective co-operative male and female formation.

5. A modular assembly as recited in claim 1 wherein said loopers and clips are molded into the respective body member.

6. A modular assembly as recited in claim 2 wherein the reference surface of said first body member is disposed at the bottom thereof, said step and one planar surface providing the underside of a platform, said loopers being positioned in said platform.

7. A modular assembly as recited in claim 1 wherein said mounting portions of said loopers and clips include means for locating said portions in the respective body member.

8. A modular assembly as recited in claim 1 wherein said second body member includes means adapted to secure the assembly as a unit in a tufting machine.
