Abstract

A method for manufacturing a deflection member is disclosed. The method may include the step of incorporating a monomer, a photoinitiator system, a photoinhibitor, and/or a reinforcing member. A further step includes blending the monomer, photoinitiator, and/or photoinhibitor to form a blended photopolymer resin. Further steps may be exposing the photopolymer resin to radiation form a first radiation source and/or a second radiation source.

First claim

What is claimed is:

1. A method for manufacturing a deflection member, the method comprising the steps of:
a. incorporating a monomer,
b. incorporating a photoinitiator system;
c. incorporating a photoinhibitor;
d. incorporating a reinforcing member having a first surface and a second surface opposite the first surface;
e. combining the monomer, photoinitiator system, and photoinhibitor to form a photopolymer resin;
f. exposing the photopolymer resin to radiation from a first radiation source towards the first surface of the reinforcing member;
g. exposing the photopolymer resin to radiation from a second radiation source towards the second surface of the reinforcing member; and
h. polymerizing the monomer to form a protuberance extending from the reinforcing member.

2. The method of claim 1 , wherein the protuberance is locked-on to the reinforcing member.

3. The method of claim 1 , wherein radiation from the first radiation source comprises a first wavelength.

4. The method of claim 3 , wherein radiation from the second radiation source comprises a second wavelength different from the first wavelength.

5. The method of claim 3 , wherein the first wavelength activates the photoinitiator system.

6. The method of claim 4 , wherein the second wavelength activates the photoinhibitor.

7. The method of claim 4 , wherein the second wavelength activates the photoinitiator system.

8. The method of claim 4 , wherein the first and second wavelengths activate the photoinitiator system.

9. The method of claim 1 , wherein radiation from the first radiation source activates the photoinitiator system and activates the photoinhibitor.

10. The method of claim 1 , wherein radiation from the second radiation source activates the photoinitiator system and activates the photoinhibitor.

11. The method of claim 1 , wherein radiation from the first and second radiation sources each activates the photoinitiator system and activates the photoinhibitor.

12. The method of claim 3 , further comprising the step of exposing the photopolymer resin to radiation from a third radiation source, distinct from the first radiation source, towards the first surface of the reinforcing member.

13. The method of claim 12 , wherein radiation from the third radiation source comprises is a third wavelength different from the first wavelength.

14. The method of claim 13 , wherein the third wavelength activates the photoinitiator system.

15. The method of claim 13 , wherein the third wavelength activates the photoinibitor.

16. The method of claim 4 , further comprising the step of exposing the photopolymer resin to radiation from a fourth radiation source, distinct from the second radiation source, towards the second surface of the reinforcing member.

17. The method of claim 16 , wherein radiation from the fourth radiation source comprises a fourth wavelength different from the second wavelength.

18. The method of claim 17 , wherein the fourth wavelength activates the photoinitiator system.

19. The method of claim 17 , wherein the fourth wavelength activates the photoinibitor.

20. The method of claim 4 , further comprising the steps of:
exposing the photopolymer resin to radiation from a third radiation source, distinct from the first radiation source, towards the first surface of the reinforcing member, and
exposing the photopolymer resin to radiation from a fourth radiation source, distinct from the second radiation source, towards the second surface of the reinforcing member,
wherein radiation from the third radiation source comprises a third wavelength different from the first and second wavelengths;
wherein radiation from the fourth radiation source comprises a fourth wavelength different from the first and second wavelengths;
wherein the first and second wavelengths activate the photoinitiator system;
wherein the third and fourth wavelengths activate the photoinhibitor.

21. The method of claim 1 , wherein the reinforcing member is submerged in the photopolymer resin.
