Abstract

In accordance with an example embodiment, a continuous belt may include an outer surface having a first edge spaced apart from a second edge defining a belt width, and a first wear indication positioned on the outer surface near the first edge and having a first width, the first width is less than the belt width, and the first width represents the amount of allowable wear of the continuous belt.

First claim

What is claimed is:

1. A continuous belt supported by a pulley, the belt comprising:
an outer surface at an outer side of the continuous belt opposite the pulley having a first edge spaced apart from a second edge defining a belt width; and
a first wear indication positioned on the outer surface adjacent to the first edge and having a surface that is visually distinct from the outer surface visible from the outer side of the continuous belt, the first wear indication having a first width, the first width is less than the belt width, and the first width represents the amount of allowable wear of the first edge of the continuous belt.

2. The continuous belt of claim 1 , wherein the first width is 5%-15% of the belt width.

3. The continuous belt of claim 1 , wherein the continuous belt is worn and needs to be replaced when the belt width is reduced by the first width and the first wear indication is no longer visible.

4. The continuous belt of claim 1 , further comprising:
a second wear indication positioned on the outer surface adjacent the second edge and having a second width, the second width is less than the belt width, and the second width represents the amount of allowable wear of the second edge of the continuous belt.

5. The continuous belt of claim 4 , wherein the first and second widths are substantially equal.

6. The continuous belt of claim 4 , wherein the continuous belt is worn and needs to be replaced when the belt width is reduced by the first and second widths and the first and second wear indications are no longer visible.

7. The continuous belt of claim 4 , further comprising:
a third wear indication positioned on the outer surface adjacent the first wear indication, the third wear indication represents the continuous belt is worn and needs to be replaced when only the third indication is visible.

8. The continuous belt of claim 4 , further comprising:
a third wear indication positioned on the outer surface adjacent the first and second wear indications, the third wear indication represents the continuous belt is worn and needs to be replaced when only the third indication is visible.

9. The continuous belt of claim 4 , further comprising:
a third wear indication positioned on the outer surface adjacent to the first wear indication; and
a fourth wear indication positioned on the outer surface adjacent to the second wear indication, the third and fourth wear indications represent the continuous belt is worn and needs to be replaced when only the third and fourth indications are visible.

10. A continuous belt supported by a pulley, the belt comprising:
an outer surface at an outer side of the continuous belt opposite the pulley having a first edge spaced apart from a second edge defining a belt width; and
a first wear indication positioned on the outer surface and having a surface that is visually distinct from the outer surface visible from the outer side of the continuous belt, the first wear indication being at a first distance from the first edge, the first distance represents the amount of allowable wear of the continuous belt.

11. The continuous belt of claim 10 , wherein the first width is 5%-15% of the belt width.

12. The continuous belt of claim 10 , wherein the continuous belt is worn and needs to be replaced when the belt width is reduced by the first distance and the first edge contacts the first wear indication.

13. The continuous belt of claim 10 , wherein the first wear indicator is positioned a second distance from the second edge, the first and second distances being substantially equal.

14. The continuous belt of claim 13 , wherein the continuous belt is worn and needs to be replaced when the belt width is reduced by the first and second distances and the first and second edges contact the first wear indication.

15. The continuous belt of claim 10 , further comprising:
a second wear indication positioned on the outer surface a second distance from the second edge and spaced apart from the first wear indication, the second distance represents the amount of allowable wear of the continuous belt.

16. The continuous belt of claim 15 , wherein the first and second distances are substantially equal.

17. The continuous belt of claim 15 , wherein the continuous belt is worn and needs to be replaced when the belt width is reduced by the first and second distances, the first edge contacts the first wear indication, and the second edge contacts the second wear indication.

18. A method of placing a wear indication on a continuous belt supported by a pulley, the method comprising:
positioning a first wear indication on an outer surface of the continuous belt at an outer side of the continuous belt opposite the pulley, the continuous belt having a first edge spaced apart from a second edge, the first wear indication and having a surface that is visually distinct from the outer surface visible from the outer side of the continuous belt and positioned near the first edge, and the first wear indication representing the amount of allowable wear of the continuous belt.

19. The method of claim 18 , further comprising:
positioning a second wear indication on the outer surface of the continuous belt, the second wear indication positioned near the second edge, the first wear indication representing the amount of allowable wear of the first edge of the continuous belt, and the second wear indication representing the amount of allowable wear of the second edge of the continuous belt.

20. The method of claim 19 , further comprising:
positioning a third wear indication on the outer surface of the continuous belt, the third wear indication positioned near the first and second wear indications, the third wear indication representing a worn condition of the continuous belt when only the third indication is visible.
