## Abstract

A method of operating a progressive die wherein the progressive die acts on a work piece having an elongated body with a blank at one end. The work piece is supported by a bandolier which is also formed in the progressive die. The progressive die acts on each blank.

## Claims

### Claim 1

A method of making products utilizing a progressive die having a plurality of work stations disposed to one side of the path of a bandolier structured to carry a plurality of work pieces, said method comprising the steps of:
a) forming a bandolier from strip material, said bandolier having a plurality of retaining members;
b) inserting a work piece into each retaining member, said work piece having a body having a first end and a medial portion, said first end being a blank that is structured to be acted upon by said work stations, said medial portion being a stem that is structured to support said blank at a location offset and spaced from said bandolier work side and positioned adjacent said work stations;
c) forming said blanks into products; and
d) separating said products from said stem.

### Claim 2 (depends on 1)

The method of claim 1 wherein said step of inserting a work piece into each retaining member includes the steps of:
feeding a length of wire on to the bandolier; and
cutting the wire at an appropriate length.

### Claim 3 (depends on 1)

The method of claim 1 wherein said progressive die includes at least one coining station, and wherein said step of forming said blanks into products includes the step of:
coining the blank.

### Claim 4 (depends on 3)

The method of claim 3 wherein said progressive die includes at least one cutting station, and wherein said step of forming said blanks into products includes the step of:
removing material from the blank to create a finished product.

### Claim 5 (depends on 3)

The method of claim 3 wherein said bandolier is further fed into additional devices structured to perform other processes selected from the group comprising: cleaning, coating, and heat treating.
