Abstract

An apparatus is provided which makes a border wire having a rectangular cross-section. The apparatus is adapted to receive a roll of wire having a circular cross-section, straighten the wire and change the cross-section of the wire to rectangular. The reconfigured wire is then accumulated, passed through another straightener, cut to size and then bent into a rectangular configuration. Opposed ends of the piece of wire having a rectangular cross-section are welded together to complete the border wire. The apparatus has an ejector which removes the completed border wire from the apparatus.

First claim

What is claimed is:

1. An apparatus for making a rectangular border wire having a generally rectangular cross-section, the apparatus comprising:
a wire holder adapted to hold a roll of wire having a circular cross-section;
a wire payoff;
a two-plane straightener downstream of the wire payoff;
a metal forming machine downstream of the two-plane straightener;
an accumulator downstream of the metal forming machine;
a three-axis straightener downstream of the accumulator;
a feed assembly downstream of the three-axis straightener;
a bender section including four bending assemblies downstream of the feed assembly, each of the bending assemblies being driven by a servo motor; and
a welder.

2. The apparatus of claim 1 , further comprising an ejector.

3. The apparatus of claim 1 , further comprising a puller or feed roller assembly driven by a servo motor downstream of the three-axis straightener.

4. The apparatus of claim 1 , wherein the bending assemblies are movable.

5. The apparatus of claim 1 , further comprising a controller.

6. The apparatus of claim 5 , wherein the controller has stored data for repeatable set-ups between wire gauges and heats.

7. The apparatus of claim 1 further comprising an electronic touch screen.

8. The apparatus of claim 1 , further comprising a means to automatically detect the position and orientation of the wire.

9. An apparatus for making a rectangular border wire having a generally rectangular cross-section, the apparatus comprising:
a wire holder adapted to hold a roll of wire having a circular cross-section;
a wire payoff;
a first straightener downstream of the wire payoff;
a metal forming machine downstream of the first straightener;
an accumulator downstream of the metal forming machine;
a second straightener downstream of the accumulator;
a feed assembly downstream of the second straightener;
four bending assemblies downstream of the feed assembly, each of the bending assemblies being driven by a servo motor; and
a welder.

10. The apparatus of claim 9 , further comprising an ejector.

11. The apparatus of claim 9 , further comprising a puller or feed roller assembly driven by a servo motor downstream of the second straightener.

12. The apparatus of claim 9 , wherein the first straightener is a two-axis straightener.

13. The apparatus of claim 9 , wherein the second straightener is a three-axis straightener.

14. The apparatus of claim 9 , further comprising a controller wherein the controller has stored data for repeatable set-ups between wire gauges and heats.

15. The apparatus of claim 9 further comprising an electronic touch screen.

16. The apparatus of claim 9 , further comprising a means to automatically detect the position and orientation of the wire.

17. An apparatus for making a rectangular border wire having a generally rectangular cross-section, the apparatus comprising:
a wire payoff for supplying wire having a circular cross-section;
a first straightener downstream of the wire payoff;
a metal forming machine downstream of the first straightener;
an accumulator downstream of the metal forming machine;
a second straightener downstream of the accumulator;
a feed assembly downstream of the second straightener;
a bender section including four bending assemblies downstream of the feed assembly, each of the bending assemblies being driven by a servo motor; and
a welder.

18. The apparatus of claim 17 , further comprising an ejector.

19. The apparatus of claim 17 , further comprising a puller or feed roller assembly driven by a servo motor downstream of the second straightener.

20. The apparatus of claim 17 , wherein the first straightener is a two-axis straightener.

21. The apparatus of claim 17 , wherein the second straightener is a three-axis straightener.

22. The apparatus of claim 17 , further comprising a controller wherein the controller has stored data for repeatable set-ups between wire gauges and heats.
