METHOD OF FINISHING A BELT SEAM USING AN ABRASIVE FINISHING MACHINE, A METHOD OF FINISHING A BELT SEAM USING AN ABRASIVE FINISHING MACHINE HAVING A PLURALITY OF FINISHING HEADS, AND A METHOD OF FINISHING A BELT SEAM USING AN ABRASIVE FINISHING MACHINE HAVING FIRST, SECOND, THIRD AND FOURTH FINISHING HEADS

1. A method of finishing a seam of a belt, the belt comprising a belt outer surface and a belt inner surface, the seam comprising a seam outer surface of a seam width with adhesive disposed thereon, the method comprising providing an abrasive finishing machine including an abrasive finishing media with a finishing surface, the method further comprising providing a backer bar, the backer bar comprising a backer bar surface with a backer surface curvature based on a backer bar radius, the method comprising:

(a) positioning the backer bar surface against the belt inner surface so that the belt outer surface contacts the finishing surface to define a finishing contact arc with respect to the backer bar radius;

(b) applying a tension, a feed rate and a pressure to the finishing media; and

(c) using the finishing machine, finishing the seam to remove the adhesive material, including adjusting the backer bar radius so that the finishing contact arc covers the seam width.

2. The method of claim 1 , the backer bar radius being adjusted by grinding the backer bar.

3. The method of claim 1 , the finishing contact arc overlapping the seam width by no more than 10%.

4. The method of claim 1 , the belt comprising an intermediate transfer belt.

5. The method of claim 1 , the seam finishing resulting in a finished seam that is imageable.

6. The method of claim 1 , the backer bar being cylindrical-shaped.

7. The method of claim 6 , the backer bar having a backer bar radius of about 1 and ⅝ inches.

8. A method of finishing a seam of a belt, the belt comprising a belt outer surface and a belt inner surface, the seam comprising a seam width, the method comprising providing a finishing machine having a plurality of finishing heads, wherein a first finishing head of the plurality of finishing heads comprises a first finishing media and a second finishing head of the plurality of finishing heads comprises a second finishing media, the method further comprising providing a backer bar, the backer bar comprising a backer bar radius, the method further comprising, at the first finishing head:

(a) positioning the backer bar against the belt inner surface so that the belt outer surface contacts the first finishing media to define a finishing contact arc with respect to the backer bar radius;

(b) applying a tension, a feed rate and a pressure to the first finishing media; and

finishing the seam with the first finishing media, wherein the backer bar radius is adjusted so that the finishing contact arc covers the seam width.

9. The method of claim 8 , the backer bar radius being adjusted by grinding the backer bar.

10. The method of claim 8 , the finishing contact arc overlapping the seam width by no more than 10%.

11. The method of claim 8 further comprising, at the second finishing head, finishing the seam with the second finishing media.

12. The method of claim 8 , the belt comprising an imageable belt.

13. The method of claim 12 , the belt comprising an intermediate transfer belt.

14. The method of claim 8 , the backer bar being cylindrical-shaped.

15. The method of claim 14 , the backer bar having a backer bar radius of about 1 and ⅝ inches.

16. A method of finishing a seam of a belt, the belt comprising a belt outer surface and a belt inner surface, the seam comprising a seam width, the method comprising providing a finishing machine having a first finishing head comprising a first finishing media, a second finishing head comprising a second finishing media, a third finishing head comprising a third finishing media and a fourth finishing head comprising a fourth finishing media, the method further comprising providing a backer bar, the backer bar comprising a backer bar radius, the method further comprising, at the first finishing head;

(a) positioning the backer bar against the belt inner surface so that the belt outer surface contacts the first finishing media to define a finishing contact arc with respect to the backer bar radius;

(b) applying a tension, a feed rate and a pressure to the first finishing media; and

(c) finishing the seam with the first finishing media, wherein the backer bar radius is adjusted so that the finishing contact arc covers the seam width.

17. The method of claim 16 , the backer bar radius being adjusted by grinding the backer bar.

18. The method of claim 16 , the finishing contact arc overlapping the seam width by no more than 10%.

19. The method of claim 16 further comprising, at the second finishing head, finishing the seam with the second finishing media.

20. The method of claim 19 further comprising, at the third finishing head, finishing the seam with the third finishing media.

21. The method of claim 20 further comprising, at the fourth finishing head, finishing the seam with the fourth finishing media.

22. The method of claim 16 , the belt comprising an imageable belt.

23. The method of claim 22 , the belt comprising an intermediate transfer belt.

24. The method of claim 16 , the backer bar being cylindrical-shaped.

25. The method of claim 24 , the backer bar having a backer bar radius of about 1 and ⅝ inches.
