Abstract

A system for treating a surface and applying adhesive to an already treated portion of the surface concurrently is presented. The system comprises surface treatment equipment, adhesive application equipment, and a common feed system. The surface treatment equipment is configured to treat the surface of an elongated member. The adhesive application equipment is configured to apply adhesive to the already treated portion of the surface. The common feed system feeds the elongated member beneath the surface treatment equipment and the adhesive application equipment concurrently.

First claim

What is claimed is:

1. A system for treating a surface and applying adhesive to an already treated portion of the surface concurrently, the system comprising:
surface treatment equipment configured to treat the surface of an elongated member;
adhesive application equipment configured to apply adhesive to the already treated portion of the surface; and
a common feed system for feeding the elongated member beneath the surface treatment equipment and the adhesive application equipment concurrently, wherein the common feed system comprises:
drive equipment having a plurality of wheels configured to contact the elongated member; and
indexing equipment configured to center the elongated member beneath the surface treatment equipment and the adhesive application equipment, the indexing equipment comprising a retractable wheel assembly configured to move towards or away from a drive wheel of the drive equipment.

2. The system of claim 1 , wherein the drive equipment includes inlet drive equipment and outlet drive equipment.

3. The system of claim 2 , wherein the plurality of drive wheels includes a first drive wheel of the inlet drive equipment and a second drive wheel of the outlet drive equipment.

4. The system of claim 1 , wherein the common feed system further comprises:
a number of roller systems to support the elongated member.

5. The system of claim 4 , wherein the common feed system is connected to a base.

6. The system of claim 1 , wherein the common feed system feeds the elongated member beneath the surface treatment equipment and adhesive application equipment at a rate in a range of one inch per second to six inches per second.

7. The system of claim 1 , wherein the surface treatment equipment comprises atmospheric pressure plasma treatment equipment.

8. The system of claim 7 , wherein a distance between the atmospheric pressure plasma treatment equipment and the adhesive application equipment is sufficiently small such that heat generated on the surface by the atmospheric pressure plasma treatment equipment increases tack of the adhesive.

9. The system of claim 8 , wherein the atmospheric pressure plasma treatment equipment is configured such that the heat generated on the surface is between 105 degrees Fahrenheit and 140 degrees Fahrenheit.

10. A method comprising:
simultaneously treating a surface of an elongated member and applying adhesive to an already treated portion of the surface of the elongated member by a system comprising surface treatment equipment, adhesive application equipment, and a common feed system for feeding the elongated member beneath the surface treatment equipment and the adhesive application equipment concurrently, wherein the system applies a surface treatment to the surface in a continuous automated fashion and applies the adhesive to the already treated portion of the surface in a continuous automated fashion, wherein the common feed system includes a plurality of wheels configured to contact the elongated member and indexing equipment comprising a retractable wheel assembly configured to move towards or away from a drive wheel of the plurality of wheels.

11. The method of claim 10 further comprising:
moving the elongated member through the system at a constant rate.

12. The method of claim 11 , wherein the constant rate is in a range of one inch per second to six inches per second.

13. A method comprising:
feeding an elongated member through a system using a common feed system;
treating a surface of the elongated member using surface treatment equipment as the common feed system feeds the elongated member beneath the surface treatment equipment; and
applying an adhesive to the surface of the elongated member, wherein the adhesive is applied to a portion of the surface after treating the portion of the surface, wherein the adhesive is applied to the surface by adhesive application equipment as the common feed system feeds the elongated member beneath the adhesive application equipment, wherein the common feed system includes a plurality of wheels configured to contact the elongated member and indexing equipment comprising a retractable wheel assembly configured to move towards or away from a drive wheel of the plurality of wheels.

14. The method of claim 13 , wherein the elongated member is fed beneath the surface treatment equipment and the adhesive application equipment at a rate of between one inch per second and six inches per second.

15. The method of claim 13 , wherein the elongated member is fed continuously beneath the surface treatment equipment and the adhesive application equipment.

16. The method of claim 13 , wherein the adhesive is applied continuously onto the surface.

17. The method of claim 16 , wherein applying the adhesive comprises compacting the adhesive using between 35 pounds per square inch and 55 pounds per square inch of pressure.

18. The method of claim 13 , wherein treating the surface of the elongated member using the surface treatment equipment comprises treating the surface with atmospheric pressure plasma treatment equipment.

19. The method of claim 18 , wherein applying the adhesive to the portion of the surface of the elongated member occurs in immediate succession after treating the portion of the surface, and wherein additional heat is not provided to the portion of the surface between treating the portion of the surface and applying the adhesive.

20. A system for treating a surface and applying adhesive to an already treated portion of the surface concurrently, the system comprising:
surface treatment equipment configured to treat the surface of an elongated member;
adhesive application equipment configured to apply adhesive to the already treated portion of the surface; and
a common feed system for feeding the elongated member beneath the surface treatment equipment and the adhesive application equipment concurrently, wherein the common feed system feeds the elongated member beneath the surface treatment equipment and the adhesive application equipment at a rate in a range of one inch per second to ten inches per second, wherein the surface treatment equipment is configured such that heat generated on the surface of the elongated member is between 105 degrees Fahrenheit and 140 degrees Fahrenheit, wherein speed of nozzles of the surface treatment equipment in rpm is in a range of 2400 rpm to 3200 rpm, wherein an input pressure for the nozzles is in a range of about 50 psi to about 90 psi, wherein system clamp up of the elongated member is in a range of 65 psi to 95 psi, wherein distance of the nozzles from the surface is 0.50 inches ±0.10 inches, wherein overlap of the nozzles is set at 0.20 inches ±0.05 inches, wherein vacuum of 18 to 24 inches of Hg is provided for a feed and cut sequence of the adhesive application equipment, and wherein a compaction roller of the adhesive application equipment applies pressure in a range of 35 psi to 55 psi.

21. A system for treating a surface and applying adhesive to an already treated portion of the surface concurrently, the system comprising:
surface treatment equipment configured to treat the surface of an elongated member;
adhesive application equipment configured to apply adhesive to the already treated portion of the surface; and
a common feed system for feeding the elongated member beneath the surface treatment equipment and the adhesive application equipment concurrently, wherein the common feed system feeds the elongated member beneath the surface treatment equipment
