## Abstract

A one-piece metal cartridge loop has no welds and no overlapping parts. The cartridge loop includes a plurality of locking tabs for positioning a cartridge therein. One end of the cartridge loop includes a coupling interface and another end of the cartridge loop includes a coupling support. A method of making the non-welded cartridge loop is disclosed.

## Claims

### Claim 1

A method of making a one-piece cartridge loop having no welds and no overlapping parts, comprising:
providing generally tubular raw material;
forming an external profile of the loop from the tubular raw material; and
forming mechanical details of the loop.

### Claim 2 (depends on 1)

The method of claim 1 wherein the step of forming mechanical details includes notching.

### Claim 3 (depends on 1)

The method of claim 1 wherein the step of forming mechanical details includes machining.

### Claim 4 (depends on 1)

The method of claim 1 wherein the step of forming mechanical details includes forming a plurality of locking tabs.

### Claim 5 (depends on 4)

The method of claim 4 wherein the plurality of locking tabs are formed by kinking.

### Claim 6 (depends on 1)

The method of claim 1 wherein the step of forming mechanical details includes forming a coupling support on one end of the loop and a coupling interface on another end of the loop.

### Claim 7 (depends on 1)

The method of claim 1 further comprising forming the generally tubular raw material by extrusion.
