Fastener manufacturing apparatus and method

1. A method of continuously manufacturing pierce nuts having a predetermined width from a metal rod with a groove disposed therealong, comprising the steps of:

providing an articulating die having a piercing station for piercing an aperture through said rod and a cutting station for cutting individual pierce nuts from said rod;

advancing the rod through said articulating die and cutting a plurality of pierce nuts, each pierce nut having an aperture pierced therethrough;

said step of cutting individual pierce nuts from said rod being defined by spacing a reciprocable cutting member of said cutting station from a distal end of said rod, a distance equal to generally said predetermined width of said pierce nut;

driving said reciprocable cutting member against said rod, simultaneously cutting two pierce nuts from said rod, including a first pierce nut at said distal end of said rod and a second pierce nut beneath said reciprocable cutting member;

said cutting member driving said second pierce nut from a plane of said rod;

said cutting station resiliently supporting said second pierce nut beneath said reciprocable member, then returning said second pierce nut to said plane of said rod;

then transferring said first and second pierce nuts in sequence in a common plane to a further station; and

affixing a wire to said pierce nuts forming a continuous strip of fasteners while maintaining said fasteners in a continuous line.

2. The method as set forth in claim 1 , wherein said step of transferring said first and said second pierce nuts from said articulating die is further defined by ejecting said first and said second fastener in an abutting relationship thereby forming a single line of fasteners.

3. The method as set forth in claim 1 , wherein said step of transferring said first and said second pierce nuts from said articulating die is further defined by transferring said first and said second pierce nuts in parallel relationship, thereby forming parallel lines of pierce nuts, then performing a further method step on said pierce nuts in said parallel lines.

4. The method as set forth in claim 1 , providing a moveable stop spaced from said cutting station a distance equal to said width of said pierce nut.

5. The method set forth in claim 1 , wherein said step of maintaining said pierce nuts in a continuous line is further defined by providing a track for maintaining said pierce nuts in a continuous line, said track receiving said first and second pierce nuts from said reciprocable cutting member in a continuous line.

6. The method set forth in claim 1 , further including the step of advancing the first and second pierce nuts in a continuous line through said track.

7. The method set forth in claim 1 , wherein said step of affixing a wire to said pierce nuts is further defined by advancing the first and the second pierce nuts in a continuous line toward a wire inserter.

8. The method set forth in claim 1 , wherein said step of affixing a wire to said pierce nuts is further defined by knurling said wire to said pierce nuts while maintaining said pierce nuts in a common plane thereby forming a continuous strip of pierce nuts.

9. The method set forth in claim 1 , further including the step of spooling the continuous strip of pierce nuts.

10. The method set forth in claim 1 , further including the step of inspecting the first and the second pierce nuts before connecting the first and the second pierce nuts into a continuous strip of fasteners.

11. The method as set forth in claim 3 , wherein said further station is a tapper, wherein said method includes tapping an internal thread in said aperture.

12. A method of making a continuous strip of pierce nuts from a metal rod having a constant width and spaced parallel grooves, comprising the following steps:

providing an articulating die having a piercing station for piercing bores though said rod and a cutting station for cutting individual pierce nuts from said rod;

advancing the rod though said articulating die piercing a plurality of equally spaced bores though said rod;

further advancing said rod though said articulating die to said cutting station, said cutting station including a reciprocating cutting member;

spacing said rod form said reciprocating cutting member a distance equal to a width of said pierce nut between said bores;

driving said reciprocating cutting member against said rod, simultaneously cutting two pierce nuts from said rod, including a first pierce nut at said distal end of said rod and a second pierce nut beneath said reciprocating cutting member;

said reciprocating cutting member driving said second pierce nut from a plane of said rod;

said cutting station resiliently supporting said second pierce nut beneath said reciprocating cutting member, then returning said second pierce nut to said plane of said rod;

then transferring said first and second pierce nuts in a common plane in a track to a tapper;

simultaneously inserting tappers in said bores of said first and second pierce nuts forming an internal thread in said bores; and

disposing frangible wires in said parallel grooves and affixing said pierce nuts to said wires in a continuous line through said track.

13. The method set forth in 12 , wherein said method includes advancing said first and second pierce nuts upwardly in a track, thereby receiving said frangible wires in said parallel grooves and affixing said wire to said pierce nuts.

14. The method set forth in claim 12 , wherein said step of transferring said first and second pierce nuts from said articulating die is further defined by transferring said first and second pierce nuts in parallel relation, thereby forming parallel lines of pierce nuts, then transferring said parallel lines of pierce nuts to said tapper.
