Abstract

A system, method, and apparatus lubricating a wire or cable during manufacturing, wherein the wire is aligned with an entry to a spraying enclosure and passes through a first seal of the spraying enclosure. Lubricant is sprayed onto the wire inside of the spraying enclosure while the unapplied, but sprayed, lubricant is collected at the bottom of the spraying enclosure. The wire passes through a second seal of the spraying enclosure, is aligned, and exits from the spraying enclosure.

First claim

What is claimed is:

1. A process for the application of a lubricant to a wire during manufacturing, comprising:
passing the wire through an entry opening of a spraying enclosure, wherein the entry opening further comprises grommets and wherein the grommets form a seal around the wire as it is passed through the entry opening;
spraying the lubricant on the wire while in the spraying enclosure;
passing the wire through an exit opening of the spraying enclosure, wherein the exit opening further comprises grommets;
wherein the spraying enclosure comprises a bottom portion of the spraying enclosure and a top portion of the spraying enclosure and wherein a gasket separates the top and bottom portions of the spraying enclosure.

2. The process of claim 1 , wherein the step of spraying the lubricant includes spraying the lubricant on the wire through at least one adjustable spray nozzle contained within the spraying enclosure.

3. The process of claim 1 , wherein the step of spraying the lubricant includes spraying the lubricant on the wire through an air system and a lubricant pump system.

4. The process of claim 3 , wherein the air system includes aerosolizing the lubricant into a mist.

5. The process of claim 3 , wherein the lubricant pump system includes filters and pumps transferring the lubricant to at least one adjustable spray nozzle.

6. The process of claim 1 , wherein the grommets of the spraying enclosure impede the lubricant from escaping the spraying enclosure.

7. The process of claim 1 , wherein the grommets of the spraying enclosure impede outside contaminants from entering the spraying enclosure.

8. The process of claim 1 , wherein the gasket impedes the lubricant from escaping the spraying enclosure.

9. The process of claim 1 , wherein the gasket impedes outside contaminants from entering the spraying enclosure.

10. The process of claim 1 further comprising the step of drying the lubricated wire as the lubricated wire exits the spraying enclosure.

11. The process of claim 10 , wherein the lubricated wire is dried with a drying device.

12. The process of claim 11 , wherein the drying device comprises an air knife to disperse excess lubricant from the wire as the wire exits the spraying enclosure.

13. The process of claim 1 , wherein the grommets comprise slit grommets.

14. The process of claim 12 , wherein the slit grommets comprise rubber slit grommets.

15. The process of claim 1 further comprising the step of collecting the unused, but sprayed, lubricant in a bottom portion of the spraying enclosure.

16. The process of claim 15 , wherein the step of collecting the unused lubricant further comprises collecting the unused, but sprayed, lubricant for reuse.

17. The process of claim 1 further comprising the step of aligning the wire with the entry opening of the spraying enclosure.

18. The process of claim 17 , wherein the step of aligning the wire with the entry opening comprises aligning the wire with an alignment assembly.
