Abstract

The present invention discloses an endless belt which is comprised of (1) a first reinforcement layer, wherein the first reinforcement layer is formed of a first fabric strip which is spirally wound forming a helix, and (2) a second reinforcement layer, wherein the second reinforcement layer is formed of a second fabric strip which is spirally wound forming a helix, wherein the second fabric strip is of essentially the same width as the first fabric strip, wherein the second fabric strip is parallel to the first fabric strip, and wherein the second fabric strip is offset from the first fabric strip.

Claims

1. An endless belt which is comprised of (1) a first reinforcement layer, wherein the first reinforcement layer is formed of a first fabric strip which is spirally wound forming a helix, and (2) a second reinforcement layer, wherein the second reinforcement layer is formed of a second fabric strip which is spirally wound forming a helix, wherein the second fabric strip is of essentially the same width as the first fabric strip, wherein the second fabric strip is parallel to the first fabric strip, and wherein the second fabric strip is offset from the first fabric strip.

2. The endless belt as specified in claim 1 wherein the second fabric strip is offset from the first fabric strip by at least 2 percent the width of the first fabric strip.

3. The endless belt as specified in claim 1 wherein the second fabric strip is offset from the first fabric strip by at least 20 percent to about 80 percent of the width of the first fabric strip.

4. The endless belt as specified in claim 1 wherein the second fabric strip is offset from the first fabric strip by at least 30 percent to about 70 percent of the width of the first fabric strip.

5. The endless belt as specified in claim 1 wherein the second fabric strip is offset from the first fabric strip by at least 40 percent to about 60 percent of the width of the first fabric strip.

6. The endless belt as specified in claim 1 wherein the belt includes a third reinforcement layer having fabric strips which are wound at an angle opposite the angle of the first and second fabric strips.

7. The endless belt as specified in claim 1 wherein the first fabric strip of the first reinforcement layer has a helix angle of no more than about 15°

.

8. The endless belt as specified in claim 1 wherein the first fabric strip of the first reinforcement layer has a helix angle of no more than about 10°

.

9. The endless belt as specified in claim 1 wherein the first fabric strip has a width which is within the range of about 0.25 inch to about 12 inches.

10. The endless belt as specified in claim 1 wherein the first fabric strip has a width which is within the range of about 0.5 inch to about 4 inches.

11. The endless belt as specified in claim 1 wherein the first fabric strip has a width which is within the range of about 1 inch to about 3 inches.

12. The endless belt as specified in claim 1 wherein the first fabric strip of the first reinforcement layer has a helix angle which is within the range of about 0.05°

about 8°

.

13. The endless belt as specified in claim 1 wherein the first fabric strip of the first reinforcement layer has a helix angle which is within the range of about 0.1°

about 6°

.

14. An endless elastomeric belt which is comprised of (1) an elastomeric layer, (2) a first reinforcement layer, wherein the first reinforcement layer is formed of a first fabric strip which is spirally wound forming a helix, and (3) a second reinforcement layer, wherein the second reinforcement layer is formed of a second fabric strip which is spirally wound forming a helix, wherein the second fabric strip is of essentially the same width as the first fabric strip, wherein the second fabric strip is parallel to the first fabric strip, and wherein the second fabric strip is offset from the first fabric strip by at least 2 percent the width of the first fabric strip.

15. The endless elastomeric belt as specified in claim 14 wherein the second fabric strip is offset from the first fabric strip by at least 20 percent to about 80 percent of the width of the first fabric strip.

16. The endless elastomeric belt as specified in claim 15 wherein the belt includes a third reinforcement layer having fabric strips which are wound at an angle opposite the angle of the first and second fabric strips.

17. The endless elastomeric belt as specified in claim 16 wherein the first fabric strip of the first reinforcement layer has a helix angle of no more than about 10°

.

18. The endless elastomeric belt as specified in claim 16 wherein the first fabric strip has a width which is within the range of about 0.5 inch to about 4 inches.

19. The endless elastomeric belt as specified in claim 16 wherein the first fabric strip of the first reinforcement layer has a helix angle which is within the range of about 0.1°

about 6°

.

20. An endless elastomeric belt which is comprised of (1) a first elastomeric layer which forms the bottom surface of the belt, (2) a second elastomeric layer which forms the top surface of the belt, (3) a first reinforcement layer which is situated between the first elastomeric layer and the second elastomeric layer, wherein the first reinforcement layer is formed of a first fabric strip which is spirally wound forming a helix, and (4) a second reinforcement layer which is situated between the first elastomeric layer and the second elastomeric layer, wherein the second reinforcement layer is formed of a second fabric strip which is spirally wound forming a helix, wherein the second fabric strip is of essentially the same width as the first fabric strip, wherein the second fabric strip is parallel to the first fabric strip, and wherein the second fabric strip is offset from the first fabric strip by at least 2 percent the width of the first fabric strip.
